The Simms Gore-Tex Repair kit is an absolute must have for those with Gore-Tex rainsuits. Even the highest quality Gore-Tex rainsuits or bibs are subject to rips and tears; especially when there's hooks involved. This is one of those items you always wish you had once its too late. Even a small tear in the outer-shell of the Gore-Tex can lead to deterioration of the garment if water finds its way inside. The packet includes a 2"x4" rectangular patch, a 1/4oz tube of Aquaseal and easy to follow instructions. Better to be safe than sorry!
