The Transpack XT1 Boot Bag is the competitor's choice because this lightweight and rugged bag will get your boots and gear to the mountain through all types of weather conditions. Using the Isosceles Storage System the XT1 has two side pockets with air/water drainage grommets that hold boots that surround a large central water resistant compartment that accommodates a helmet and gear. This system diverts the weight and bulk from the boots and diverts them to the sides away and away from your back creating a natural suspension that is ergonomic and comfortable. And for carrying this XT1 is also equipped with closed cell foam padded back and adjustable neoprene padded shoulder straps for added comfort while carrying. Constructed with a super tough water resistant 600 denier coated polyester and industrial strength material and double locking self repairing nylon coil zippers with mesh side pockets and top lid pockets and components the XT1 will withstand the weather and your travel needs for years to come.
