Icebreaker's Oasis Crew is an ideal long sleeve baselayer that fits well under any shell or mid layer. With close athletic fit, this is an ideal top that breathes extraordinarily well and wicks moisture, too. Whether it's a warm, dry climate or cold and clammy you can expect only the best performance from the Oasis Crew.

A fundamental - to be worn for weeks on alpine routes, washed in glacial streams and dried in the slipstream of a bus window. Patagonia's new Capilene® 3 Midweight provides excellent insulation and ultimate comfort next to the skin.

The sweaty work of breaking trail on a powder day sets you up for a big chill once you stop. Capilene® 2 Lightweight, Patagonia's fastest-drying performance baselayer, keeps you dry during endurance activities and insulates when skies turn dark. Redesigned for 2010!
