This week we are pleased to present a guest post by Carin Clevidence, who is the author of the novel, The House on Salt Hay Road. She lives in Northampton, MA, with her two children and travels with them whenever she can.
The first time I went to Antarctica I completely overpacked. I pictured myself shivering in a frigid wasteland. So, I added layer, after layer, of polar fleece to my overburdened suitcase. It nearly burst, stuffed with fleece and polypropylene, ski masks, neck gaiters, and a fleece-lined deerstalker hat.

Most of it waited out the trip in my cabin closet.

Yes, it's important to be prepared in the coldest and most remote landscape in the world. But unless you're a research scientist, you're going to Antarctica during the austral summer, December through early March (which is, of course, winter in the northern hemisphere). On the Antarctic Peninsula, the temperature averages in the thirties (Fahrenheit). Chances are you'll be glad you brought your sunscreen.
So, what should you really pack when you're headed to Antarctica? Here's the complete list:
Essential Antarctica Packing List

Parka

You'll need one, but don't bother to bring your own. Again, unless you're a researcher, you're going on a cruise ship. You'll be given a parka in a bright color - usually red - because they want you to show up against the ice.

Knee High Waterproof Boots

These should be good ones, preferably insulated. You'll use them to get from the cruise ship to the uninhabited shores, riding in an inflatable landing boat.

Called by their brand name, Zodiac, these run-abouts are made of heavy duty, rubber-like material. They carry about 12 people at a time, and are nearly indestructible. There aren't docks or jetties in the Antarctic. You disembark from the Zodiac directly onto the beach, often stepping into the water. Your boots should come up at least to mid-calf. Ankle high boots will not cut it. Trust me, you do not want wet feet!

If you choose to bring your own, don't worry if they aren't insulated. I wore a pair of LL Bean Wellies with two pairs of warm socks, and that worked fine. The pros prefer Bogs or Muck Boots.

A note on tread: Avoid rubber boots with a deep tread. Penguin guano can be hard to wash out of those little nooks and crannies.

Waterproof Pants

Zodiacs are open boats. You'll be exposed to spray and the occasional wave. Lightweight waterproof pants in a pull on style are best. You can wear them over a warm insulating layer. Make sure to get good quality ones that won't tear. Once on shore, you may want to sit on the ice while taking photographs. In some places, like Paradise Bay, you may be able to slide down a snowy hillside.

In general, you want clothes you can layer. Pull on waterproof pants are a better choice than snow pants, because you can easily take them off if they're not needed. Also, they're easy to clean. Depending on the weather and the time of year, penguin rookeries can be very messy. Waterproof pants are essential.

Base Layers

Pack a couple of pairs of thin, warm base layers that don't itch. Silk, polypropylene, Smartwool, whatever you prefer, or have on hand.

If you're not sure how to pack for a cold weather trip, you'll want to think layers, and good quality fabrics that will wick sweat and keep you warm.

Warm Socks

Pack plenty. They can get wet. Cold, wet feet are not only uncomfortable, they can be dangerous. Buy quality if you can. The Tortuga team members are big fans of Smartwool for durability, warmth and long term value.

A note about laundry: Some ships give you the option of a public laundry room. Others offer a laundry bag that you leave for the cabin steward. The latter is convenient, but expensive. Adjust your sock and underwear allotment accordingly. Hand washing socks and underwear during your shower is another option to stretch your wardrobe and minimize what you pack.

Hat, Gloves & Scarf

Pack:

Two pairs of waterproof gloves or mittens, and glove liners if you like

A scarf, or neck gaiter

A hat, warm & windproof

Your hat does not need to be a fleece-lined deerstalker. But it should cover your ears. There will be cold wind on the boat and the ice. Be prepared to stay warm.

Sunscreen

I'm serious. Pack high SPF sunscreen and make sure to wear it. The ozone layer is at its thinnest above Antarctica, and there is significant glare from the white snow and ice.

Everyday Clothes to Wear Onboard

Onboard you'll want to dress in comfortable clothing. Bring footwear you can slip into quickly. There are great views of wildlife and scenery from out on deck. You don't want to risk missing a pod of orcas because you had to lace your shoes.

A note on footwear: Unless you plan to dress up, you can get away with only two pairs: waterproof boots, and something comfortable to wear onboard, both inside and on deck. If there's an exercise room available and you plan to use it, bring sneakers. Otherwise, I'd avoid anything with laces.

Tidy Wear

Some ships are more formal than others. In general though, passengers on expedition cruises tend to leave the sequined ball gowns at home. Do pack something nice to wear for the Captain's Welcome Dinner. In my family, this is known as "tidy wear."

The last time I went, I brought a pair of lightweight flats in addition to my wellies and my onboard pull-on boots. If, like my mother, you believe that packing light trumps fashion, don't worry. The Captain isn't going to take offense if you show up in a nice sweater and a pair of slacks. But change out of those rubber boots, and brush your hair.

Other Gear

Camera

You are going to one of the most dramatic landscapes on earth. And it's inhabited by penguins! Pack the best camera you can afford.

Binoculars

These are particularly useful for spotting whales and sea birds from the ship. A small, packable pair is best. If you don't have a pair and are unsure about what to buy, check out this binoculars buyer's guide, which compares the options by size, field of view, weight, rating, and cost.

Backpack

For the Zodiac ride to shore, you need a lightweight daypack to store camera gear, binoculars, hats, and gloves. The last company I traveled with, A&K, gave these out with our parkas. Waterproof is best, because Zodiacs can get wet.

Waterproof Camera Bag

This is good insurance in the event of a wet Zodiac ride. A heavy ziploc bag works fine. Traditional expedition grade, roll top dry bags are another option if you don't want to invest in an expensive waterproof camera bag.

Sunglasses

Again, it's summer down there. The sun can be very bright, blazing on all that ice and snow. You don't want headaches from constantly squinting, nor do you want to miss something spectacular. Polarized lenses are a great idea.

Seasickness Medication

If you are prone to seasickness, bring whatever works. Some people swear by acupressure bands, others prefer scopalomine patches, Dramamine, or ginger. Bonine is a brand name, once per day, anti-nausea med that will not put you do sleep the way Dramamine has a tendency to do.

The Drake Passage between the tip of South America and the continent of Antarctica is the roughest stretch of ocean in the world. I've been incapacitated on crossings of the Drake, and other times felt fine. Some of it depends on weather conditions and some on the ship's stabilizers. You may get lucky, and experience the Drake Lake. But come prepared for stormy seas.

Something to Read

You'll have some days at sea. Assume that you won't be seasick, and pack a couple of good books. Some of the best adventure stories ever written take place in Antarctica. Endurance: Shackleton's Incredible Voyage, by Alfred Lansing, is a classic.

I particularly recommend The Worst Journey in the World by Apsley Cherry-Garrard for his descriptions of a sledge journey during the Antarctic winter. Put it on your Kindle, though - the book's the size of Moby Dick.

Consider Renting

Some Antarctic travel companies now offer the option of renting gear. You fill out an online form and your selections are waiting for you onboard. It's not cheap, but it keeps you from having to haul bulky rubber boots halfway around the world. It's less expensive than purchasing a whole range of new gear that you may never use again if you live in a warmer climate.

Renting gear is one strategy for managing to pack light, and keep it to a carry on, even when you take gear heavy, expedition grade trips. If your Antarctic explorations are just part of a larger journey, then renting might make a lot of sense for you. It's worth checking out.

TL;DR

Unless you're a research scientist, you'll be traveling to Antarctica during the austral summer. Temperatures on the peninsula are in the 30-40F range. Don't forget:

A parka will be provided onboard your ship.

Insulated waterproof boots that reach at least mid-calf

Waterproof pants are essential

Warm socks: several pair

Wool is best for warm base layers

Hat, scarf & gloves

Seasickness medication

Consider renting the gear you need

And don't forget sunscreen and sunglasses! The glare on the ice is intense.

The xwartic  is not just a backpack. it is the future of cold weather. Your gear will be covered in a unimpenitrable covering of kelvar. your water will freeze  but there is no need to fret. the backpack can unthaw it! the back pack has a crank that will heat up your water until it is not ice, it will be water. the crank will be easy to use and very light.  even better if you find a
glacier you can chip off some of it, put it in you pack, and turn the crank. the ice will turn to glacier water. so in the artic you need not worry about water.
if you ever need to get geared up for a arctic adventure just get the xwartic for all of your essential needs.

We went down several design avenues when selecting the right pack for an expedition like this.

It all came down to what sort of pack would be most appropriate for a route and environment like this. So, let's start with key features of the route, and location/season, that might affect pack selection:

1. It's going to get wet. A pack that absorbed as little water as possible, and was as effective as possible, at keeping water out of the packbag, are desirable features. This is a wet environment. It rains a lot, we're camping on wet ground, and we have dozens of rivers to cross - some that require swimming. The pack needs to keep the contents dry.

2. It needs to carry weight. We're humping 50+ pounds of food, and a little bit of gear, at the beginning. The pack also needs to be "soft" enough so as not to inhibit mobility while moving fast with very light loads towards the end, for our highest mileage days.

3. It needs to adapt to variable load volumes. This criterion alone elimintaes most of the packs on the market, which are poorly compressible in large volumes and don't generally carry gear on the outside well in larger volumes. All the gear needs to fit inside the packbag (for river crossings), yet the packbag must be adaptable to a rapidly shrinking load volume as the trip progresses. In other words, a small load must also result in a small pack (in contrast to a small load carried poorly in a big pack) in order to maximize our efficiency and comfort for high mileage days and rapid pace towards the end.

4. It must provide immediate access to all essential gear used throughout the day without having to access the packbag. That means we need to be able to reach two liters of water and 2000 calories of food without taking off the pack, and being able to grab wind and rain gear without opening the packbag. The goal here is twofold: we don't want to waste time dealing with gear, and we don't want to expose gear inside the packbag to the elements unnecessarily.

This criteria led the development of custom "dry bag harness" packs by ULA Equipment, affectionately and informally denoted as the "ULA Arctic Dry Pack". The packs are based on a design by Roman Dial for Alaska trekking and packrafting, and implemented in various forms in the past by Dana Design and Cascade Designs, and since then, pretty much "upgraded" to a state of dysfunctionality in some form or another by these and other manufacturers (or in the case of Cascade Designs, discontinued altogether).

The ULA Arctic Dry Pack integrates two key components: a dry bag and a harness.

About the Dry Bag. We have selected the Pacific Outdoor Equipment 65L Pneumo Dry Bag (12 oz / 340 g) for our packbag. We tested so-called ultralight dry bags from other manufacturers, including Outdoor Research (seal not waterproof under immersion, outer fabric absorbed significant quantities of water) and Sea to Summit (neither seals nor seams waterproof under immersion, poorly durable fabric*). The POE Pneumo proved to be completely waterproof at its closure, seams, and fabric, even under significant immersion pressure. It also offered slots at the bottom of the bag through which compression straps could be threaded to cinch a heavy load into the lumbar region of the pack harness. Finally, it comes with an air exchange valve, which is a very nice feature for (1) compressing the packbag as much as possible while hiking for best load stability, and (2) inflating the packbag for river crossings to improve flotation and minimize the net pressure of water against the packbag fabric during immersion.

* The Sea-to-Summit Ultra-Sil Dry Sacks deserve a fair assessment here. First, they are not designed or intended to withstand the water pressures of immersion. They are intended to provide rain protection to gear while packed inside a backpack. Ryan will be using Ultra-Sil Dry Sacks inside his main POE pack dry bag for his sleeping bag, insulating clothing, and satellite phone electronics.

The image to the right shows the packbag in "inflated" mode when in the harness.

About the Pack Harness. The ULA Arctic Dry Pack offers the following features, and weighs 24-30 oz (depending on size and other options):

Dry Bag Compression System. One outer harness, one top cinch strap, and three sets of side cinch straps for securing the dry bag to the pack harness (see image to right).

Replaceable / Customizable Back Pad. Can be adjusted to accomodate variable types of padding and frame stay configurations. For example, Ryan's backpad is constructed of a dual density foam and twin frame stay sleeves for load transfer.

Wide, but Thinly Padded Hip Belt & Shoulder Straps. To maximize surface area for load transfer without inhibiting movement or binding under heavy weight (see image below).

Large Hip Belt Pockets. Each pocket can hold 1,000 or more calories of food (see image below).

Rear Mesh Pocket. Rear mesh pocket has three openings (center and two sides). Side openings have elastic drawcord closures and are accessible while wearing the pack. Perfect for water bottles. The center opening can be used to stash clothing, more food, or trekking poles. (See image to right).

Bear Spray Holster. Shoulder strap offers a bungee system for securing a can of bear spray.
