The Womens Oasis Long Sleeve Crewe has developed into an iconic base layer for good reason. Velvety soft, breathable 200gsm merino jersey warms in cold weather, is highly breathable in warm weather and gets even softer over time. The details of the Oasis Long Sleeve Crewe make it particularly easy to move - ideal as part of a layering system under a mid-layer or jacket, but also solo for running or hiking in cooler conditions. Flat seams prevent chafing, while an extended back panel and set-in sleeves ensure comfort under a backpack. And because merino is odour-resistant, you can wear it several times before it needs to be washed.
