Gear Review: Arc'teryx Delta LT Zip

A super-versatile, fleecy layering piece

Is it a high-loft baselayer or an ultrathin midlayer? Both, actually. After using Arc’teryx’s Delta LT Zip through four seasons of weather, our tester says, “Fleece has made it back into my multiday layering system, thanks to the versatility and low bulk of the Delta. It’s thin and soft enough to wear next-to-skin in winter, and warm enough for a midlayer in mild weather. $99; 10 oz.; arcteryx.com
