Our super lightweight Helvellyn DRY Gaiter uses ripstop polyester reinforcement lower panels and DRY waterproof and breathable technology on the upper panels. An elasticated ankle and rear hem keep the gaiter secure around the boot, while the zip and hook and loop storm flap prevent any mud or debris sneaking in. The snug trekking fit and and snag-free split drawcords make these an ideal choice for wear during tough adventures in the outdoors.
