If comfort is a priority, don't look any further. The set-in sleeves, offset shoulder seams and flat-lock stitching all contribute to this base-layer's level of comfort and mobility - no matter what you are doing. The 200gm Jersey Merino fabric is so soft, so breathable and so great at regulating your body temperature - so that you will feel great in any weather. In addition, the merino wool naturally resists odour, so you can wear your Oasis base-layer for days on end - and it will still feel great.
