The Strata Merino Zip-off Thermal Bottom is the long john you never knew you needed. It brings a new era of innovation to your ADV layering kit. Full-length separating side zips allow you to easily de-layer without removing your boots or pants. No more sacrificing comfort for convenience. No more dancing out of your pants when things heat up. Just drop your trousers and unzip the base layer to remove them trailside. So quick and easy, you might even be able to get them off (or on) before your buddies catch up.
