Technical fabrics have taken over athletic apparel for a good reason. You want the sweat to wick-away from your body during a workout, not stick to your shirt and get heavy like a traditional cotton T-shirt. This is true whether you’re in the gym or outside running, hiking, or biking — which is why when it comes to shirts designed for these activities, non-cotton fabrics are basically all you’ll find. There is, however, one drawback with many technical fabrics: They stink. Or to put it more diplomatically, they hold on to odors, both while on your body and sometimes even after a trip through the wash.

The LaSportiva Kuma 2.0 T-shirt fixes this problem by using treatment called Polygiene, an environmentally safe process developed by a Scandinavian company that uses silver chloride, a naturally occurring salt that it gets from recycled electronic equipment. The treatment basically stops odor causing bacteria from developing on your sweaty shirt. After a workout, you can simply air-dry your shirt and you’ll be impressed that the shirt doesn’t have that after-workout stink. It’s a great option for backpacking, traveling, and other activities that require you to use a shirt multiple times before washing. For runners and cyclists, it’s great to enjoy that post-activity meal or drink without stinking up the joint.
