The Women's Oasis Long Sleeve Crewe is an iconic baselayer for good reason. Made from our super-soft, breathable 200gm merino jersey fabric, the Oasis Long Sleeve Crewe keeps you warm in cool weather, breathes well in warm conditions, and only becomes softer with age. And the details of this shirt make it incredibly comfortable when you move, so it is an ideal baselayer under a top or shell, and great for wearing alone on a cool morning run or a hike in the mountains. Flatlock seams won't chaffe, a drop hem for more coverage, and set in sleeves keep it comfortable under a pack. And because it is merino, you can wear it several times between washings, odor free.  Weight:   200 Lightweight  Fabric:   100% Merino wool Fit:   Slim  Layer:  Base Layers Best for:   Outdoor & Hiking,  Snow Sports,  Travel & Lifestyle Benefits:   Soft, warm, breathable Features:   Offset shoulder prevents pack rub, flatlock seams prevent chafing, drop tail hem for added coverage, Icebreaker Merino heat transfer logo
