Icebreaker Mens 200 Oasis Base Layer Top

The Icebreaker Men’s 200 Oasis Long Sleeve Crewe Top is crafted to be your essential base layer, designed to keep you comfortable across all outdoor adventures. Made from 100% merino wool, this lightweight top offers natural temperature regulation, keeping you warm when it’s cool and breathable as you start to heat up. Whether you’re trekking through a forest or setting up camp on a chilly morning, the Oasis Crewe layers effortlessly under jackets or fleeces, giving you versatility for all-weather wear.

One of the standout features of the 200 Oasis is its thoughtful design for comfort in motion. With offset shoulder seams, it prevents chafing, even with a fully loaded backpack, while the underarm gussets offer increased breathability right where you need it most. Plus, flatlock seams eliminate any irritation, ensuring a smooth, second-skin feel on extended adventures. Odour resistance is a natural benefit of merino wool, making this top ideal for multi-day wear without worrying about freshness. This is the top you’ll reach for, season after season, to keep up with your every move. Ready to make it your next go-to layer?
