has anyone got one? (small bag.. size of a bum bad, wih adjustable strap that tou clip through your belay loop)
made by/distributed by a spanish company called columnverte i think, we tried one in feb in spain.. really simple idea... we improvised by using a rolled up towel with some slings and clove hitch to adjust... cheaper than belaying glasses too.. saved neck ache.. not sure if it would work long term though
