A supplemental pack for increasing storage on longer trips or where space within the frame is at a premium. The Backcountry Rear Top Tube Pack is a convenient space to store frequently used items and add additional storage to mountain bikes with limited space for packs. The rear top tube bag is designed for modern mountain bike geometries and fits the rear of the top tube better than simply reversing a Backcountry Top Tube Pack. It is ideal for stashing snacks, tools and anything that you want close to hand and attached securely to the top tube and seat post with Hypalon-reinforced velcro straps that minimise abrasion A one-finger zipper puller allows easy access to the mountain bike rear top tube bag on the move, while the full-length fully waterproof zipper safeguards contents against water and dirt when closed. The bag is also padded with closed cell foam to safeguard items against impact and has an internal anti-rattle mesh pocket for small items. Materials The Backcountry Rear Top Tube Pack is made from our proprietary 420D nylon; a rugged fabric made to our own exacting specifications for durability and waterproofing. Designed to fit the demands of off-road riding, this material offers full waterproofing, minimal weight, low stretch, and high abrasion and tear resistance. Notably, it’s welded together at the seams, creating a watertight seal that ensures the saddle bag remains completely waterproof. Care Hand wash, using a mild diluted soap if necessary. Afterwards, let it air dry. Do not machine wash, machine dry, or iron.
