What Our Gearhead(R) Experts Are Saying:"I wore this under my hiking pants on a chilly early season trip and never felt a seam the entire day, the flat construction really does disappear against the skin. It kept me warm on the climb and never felt clammy once I started sweating."The 200 Oasis Legless Legging from Icebreaker earns its spot as a base layer for long days that start cold and warm up fast. We reach for it under hiking pants or a cycling kit when the morning air still has a bite to it, and the merino wool regulates temperature as the effort builds through the day. The slim fit holds close to the body for consistent coverage, while flat seam construction lies smooth against the skin, cutting down on friction across hours on the move.
