Icebreaker MER 200 OASIS+ LS CREWE

The Icebreaker MER 200 OASIS+ LS CREWE is a warm long-sleeve merino baselayer designed for dependable comfort in cold-weather adventures. Its 100% merino wool construction offers natural warmth and breathability, while the substantial 200 g fabric works smoothly beneath midlayers or outerwear.

Offset shoulder seams help reduce irritation under heavy backpacks, and flat, low-profile seams minimize chafing during movement. Underarm gussets support mobility and ventilation, while thumb loops help keep the sleeves securely in place—making it a strong choice for skiers, ski tourers and cross-country athletes who value comfortable performance close to the skin.
