An extended secure space for storing frequently-used items, whatever the terrain. The Backcountry Long Top Tube Pack is a convenient space to store frequently used items, particularly on mountain bikes with sloping top tubes or limited space inside the main frame triangle. The long top tube bag for mountain bikes is ideal for stashing snacks, light valuables and electronic devices. It features an internal divider and mesh pocket and securely attaches to the top tube with Hypalon-reinforced velcro straps to minimise abrasion. A one-finger two-way waterproof zipper puller allows easy access on the move and safeguards contents against water and dirt when closed. The long top tube bag also features a padded foam base to protect contents and a battery lead port for charging electronic devices on the go. Fully waterproof two-way zipper Protected cable port Slim-line design to avoid knee rub Internal pocket for organisation Reflective graphics for enhanced visibility Ultra-durable, lightweight body fabric SPECIFICATIONS Materials The Backcountry Top Tube Pack is made from Dimension-Polyant VX21, a four-layer laminated fabric originally developed for the maritime industry and 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, these materials offer full waterproofing, light weight, low stretch, and high abrasion and tear resistance. Notably, it’s welded together at the seams, creating a watertight seal that ensures the top tube pack remains completely waterproof. Care Instructions Wash the top tube bag by hand, using a mild diluted soap if necessary. Afterwards, let it air dry. Do not machine wash, machine dry, or iron. APIDURA We’re an independent, family-run business of cyclists, makers and problem solvers, brought together by a shared mission to find better ways to explore the world by bike. Apidura was born from necessity; pioneering ultralight, rackless packing systems to help us take our love of cycling further and allow riders to unlock their instinct for adventure. As devoted adventure cyclists, we design with our fellow riders in mind, creating products that address genuine needs and bring new value to the bikepacking scene. We create the best packs we can, using technical materials and precision crafting techniques – and when we find a way to improve them we do so straight away and without fanfare. We don’t do ‘seasons’, limited editions or discount our gear – we simply create the best possible technical bikepacking gear that’s built to last.
