Silky-soft Capilene 1 is the lightest of all our technical baselayers. A master at managing moisture to keep you cool during active use in warm to sweltering conditions, it also helps protect from the sun and acts as an excellent quick-wicking baselayer beneath heftier Capilene or wool insulation when the mercury plummets. Made from 100% post-consumer recycled (and 100% recyclable) Capilene 1 polyester, with Gladiodor natural odor control. Made in USA. Common Threads Recycling ProgramResearch shows that the environmental impact of recycling worn-out Capilene base layers into new polyester fiber is significantly lower than making that same fiber from virgin materials. Taking into account that worn-out garments are diverted from trash incinerators, making new polyester fiber from recycled garments results in an energy savings of 76% and a CO2 emissions [greenhouse gasses] reduction of 71%, versus creating that fiber from new raw material.

best base layer out there
I love these shirts. perfect first layer for what I use them for - saltwater flyfishing. Light, silky, and very comfy. Dries quickly and, unlike other shirts of this type, doesn't have a weird odor after use. I've completely made the transition to synthetics while out on the water in my kayak, and Patagonia does synthetics best. The Capilene 1 is the best!
