Some people completely overlook underwear as the foundation of layering. Big mistake. If you haven't already tried our best selling Altitude Full Briefs and Zodiac Crop, you're well and truly missing out. Rest assured, they're every bit as soft, lightweight, warm and comfortable as the rest of our high performance thermal layers - and if you buy them as a bundle, you’ll get a great deal too.

Both crop and briefs are made with 170gsm lightweight 96% superfine Australian Merino and 4% Elastane MicroMerino - for an easy four-way stretch and freedom of movement.
