Marmot’s much-loved DriClime Vest is versatile, very lightweight and tough. A wind resistant, water repellent outer shell teams with a microfleece lining, with a gap between them to trap air and enhance breathability (if they were bonded together, the breathability would be dramatically reduced). Despite the vest being flyweight, this air gap gives more insulation than you expect. It dries extremely quickly, making it a useful backpacking layer. A shirt hem (no drawcord, and cut with a small fl are and shallow side slits) provides a versatile hip fit and for tucking under a rucksack hipbelt. Zipped side pockets are roomy and an inside chest pocket is useful. The cut is designed to fi t over a base layer and, at most, a single-skin windproof shell or microweight mid-layer. The clue is in the collar and armholes which are static and relatively narrow. This is an excellent garment for fastmoving sports (mountain running, ski touring, mountain biking; I’ve also used it sea kayaking) or for easy layering when weight is of the essence. The men’s version has an elastane-bound hem and armholes.
