Plus, it’s very light and soft and gives you freedom of movement without bulk. For anything from trail hikes to training runs, you’ll find all-day comfort in this teeOur VerdictSoft, breathable and fast drying, this is one of the easiest tees to wear for warm-weather movement.The Smartwool Active Ultralite Short Sleeve Tee weighs 102g (UK 12) and uses a Merino-TENCEL blend that feels natural but dries faster than standard Merino. I really value that mixit balances next-to-skin comfort with better moisture handling, especially during higher-output efforts. Its also odour-resistant, which makes it ideal for multi-day use.The fit is relaxed rather than close, so if you prefer a more performance-oriented cut, consider going down a size. The stitching is clean and sits flat, and the island doesn’t irritate under a pack. The fabric isn’t the toughest Ive used, but for a base layer thats this breathable and comfortable, thats a trade-off Im happy with.This is my go-to baselayer, especially for multiday hiking.
