When heading out on a ski vacation it's best to have a good bag to carry all your skiing accessories. For these occasions there is the Transpack XT1. Made with a tough water resistant polyester, this boot bag was designed with two side pockets specifically for your boots and a large water resistant central compartment that will hold a helmet, gear, even an extra pair of boots if there are two of you. This Isosceles Storage System creates a natural, comfortable weight diversion so that you're not carrying all the weight on your back. The boot pockets are outfitted with drainage grommets which allows for the evaporation of water and moisture and there are two additional zipper mesh pockets on the exterior for more storage space. Inside the bag there's a zippered padded pocket to hold your personal items. The shoulder straps are neoprene padded and the back is padded with a closed cell foam for a comfortable fit when you carry the bag through the airport or from your car to the mountain. Well-constructed and easy to clean, the Transpack XT1 is an excellent choice for the winter season. Isosceles Storage System. Water resistant coated 600 denier polyester.
