So what to wear while in Antarctica???
Like every expedition I've participated in (all of which were trekking/ mountain hiking) , the company would provide you with something called a "Gear list". And again, weather and/or terrain dependent, the list changes with any expedition. In Antarctica however, terrain is only an issue during zodiac landings meaning, your feet get some break from wearing those boots that you can't wait to take off. Antarctica XXI provided us with a gear list as well. But my gear list is based on my personal needs as follows:
HEAD
1. HAT : a beanie hat, those kinds that cover your ears would be a bonus. Sun hat can also be helpful as the sun can be very harsh even though it's a cold environment. I did experience some sun burn on my face even with sunscreen. Sun reflected off the snow can do some damage.
2. EYEGLASSES: ski goggles are not needed but can be used if preferred. I used Suncloud polarized glasses. A Julbo glacier glasses would also be a good choice.
3. BALAKLAVA/ EAR MUFFS: I never had to use one because we were lucky to have 32F weather but with windchill factor, this can be helpful. I packed one just in case.
BODY
1. BASELAYER: I've used Patagonia's capilene baselayers in the past which has great moisture wicking properties but have recently favored the merino wool type fabric. Merino wool's awesome properties include moisture wicking, temperature regulation (cools you off when it's hot, warms you up when it's cold) & antimicrobial properties so you can wear it for more than one day and not have to worry much about odor. There are several brands who make these, Ibex, Smartwool, Stoic, Icebreaker. I've used all except Ibex.
2. INSULATOR: either a soft shell, fleece, down jacket or fleece and down together or fleece and soft
shell together or soft shell and down together. Basically, whatever makes you comfortable. In my case, I was wearing Mammut's 750 fill down jacket on top of my baselayer and had a fleece jacket in my pack just in case.
3. OUTERSHELL/LAYER: this has to be windproof and waterproof. Some wore their ski jackets but I prefer the light packable ones made by Arcteryx. I have the Alpha SL Arcteryx which is highly packable and lightweight at 7 ounces. It's made of Goretex and is "guaranteed waterproof/windproof". I'm making a special mention about it's waterproofing and wind proofing properties because waterproofing has different categories. Some would say 20,000mm waterproof
rating or DWR which means Durable Water Repellent. Basically, if not sure which to choose, anything that says 3D Goretex is one of the best choices. Make sure it's also breathable i.e. "pit zips".
Lots of brands make these kinds of jackets. Arcteryx is on the more expensive side but my jacket has withstood expeditions like Everest Basecamp and Patagonia and numerous mountain hikes in Southern California such as 6 peaks and Mt. Whitney. And it pays for itself with lifetime warranty.
LOWER BODY
1. BASELAYER: same is true with lower body. A capilene or merino wool baselayer is recommended. I used Stoic merino wool baselayer.
2.INSULATOR: this is a personal preference. Some wore baselayer and ski pants which have built in insulation. I carried fleece pants just in case.
3. OUTERSHELL: some used ski pants. I used REI's Mirula mountaineering pants. Highly packable and lightweight. I have used the same pants during a mountaineering school and summit at Mt. Washington in New Hampshire as well as Patagonia.
FEET
1. BOOTS: Antarctica XXI provided us with Bogs waterproof boots which we returned later. Prior to expedition Antarctica XXI asked for my boot size.
2. SOCKS: most of my hiking socks are merino wool for the reasons I mentioned above but ski socks are good choices for this trip. But in my case, I used REI's mountaineering socks for more warmth and cushion.
ACCESSORIES
1. GLOVES : fleece gloves are appropriate. In my case, I used microfiber inner gloves that came with my Burton ski gloves. Ski gloves or in my case, Burton gloves are good to carry just in case the windchill factor drops . These outergloves have to be waterproof and windproof. The Burton gloves I used have pockets on the outside for hand warmers if needed.
If you noticed, I've mentioned merino wool, moisture wicking , packable, lightweight, waterproof, windproof and breathable more than once. These are my preferred gear list in every expedition I have participated in and it also works for Antarctica.
Note: We were required to wear a lifejacket that appears like a tubular vest that inflates automatically when you hit the water. Required especially when riding the Zodiac.
