I'm looking for thoughts on what kind of pants are needed for Antarctica, when we are off the ship on the zodiac, kayaking and exploring? I've read different things and am looking for more feedback. I know to start with a base layer and then a mid-layer for warmth. But of the outer layer, should it be rain pants (no warmth) or snow pants (with warmth)? Any insight on what to wear, especially for the pants, is appreciated. Thank you!
