Sea to Summit Alpine Event Gaiter. A really nicely made & high performance trekking & mountaineering gaiter. The uppers are made from lightweight Event fabric which is waterproof & highly breathable, whilst the lower section is 500D Cordura for ultra tough abrasion resistance. Hypalon instep patches add even more protection & the removable under boot strap is also Hypalon for long life. A 38mm velcro closure makes getting these gaiters on & off quick & easy & a robust double riveted lace hook holds them securely in place. Just a really nicely thought out & well made gaiter with a good height to suit longer legs or provide more protection.
