The mountain Equipment Alpine Pro Shell Gaiter is close a fitting classic mountain gaiter with a full Gore-Tex Pro Shell upper to maximise breathability. The front opening zipper & Velcro strap make for easing donning & the close fitting ankle & lace hook provide a secure lower seal while the calf draw cord stops the gaiter from slipping down. The lower third of the gaiter is made from a durable 500 Denier Nylon fabric to resist vigorous abrasion from things such as alpine boots, skis & crampons & the underfoot strap is fully replaceable if you do manage to wear through it. Great for all round use in the mountains or just general walking in wet or snowy conditions. Remember! In the wet the gaiter goes under your trouser leg to stop water running down the trouser & in to your boot, & in the snow its goes over to stop snow going up under your trouser leg. 3-layer GORE-TEX 40D upper 500D nylon reinforced lower leg Close fit around ankle Front opening zipper with Velcro flap Rear drawcord adjustment Replaceable underfoot strap
