Apidura Frame Pack Hydration Bladder - 1.5 L
The Apidura Frame Pack Hydration Bladder is the first hydration bladder designed specifically for bikepacking frame bags – a convenient way to drink hands-free. Available in 1.5 L (120 g) and 3 L (150 g), it sits in the base of a full frame pack and comes with a detachable 1.2 m hose and bite valve that route to your handlebars.
Why a frame pack bladder – and why this one
A full frame bag often leaves no room for bottle cages, and stopping to dig out a bottle breaks your rhythm. The Frame Pack Hydration Bladder turns the frame triangle into your water tank:
- Water without bottle cages. It is shaped to fit inside full frame bags, so you can carry water even when there is no space for cages – and the weight sits low in the frame.
- Drink without stopping. The detachable hose is long enough to reach the handlebars, and the included clip fixes it to the cockpit or frame with Velcro.
- Refill without unpacking. The wide roll-top opening makes refilling easy while the bladder stays in the pack, from any water source.
- It stays put. A stability strap clips into the accessory clips of the Backcountry Full Frame Pack for additional stability.
- Clean, safe water. The 100% TPU bladder is PVC- and BPA-free, odour-resistant and certified food-safe to EU and FDA standards.
Who is it for?
- Bikepackers using a full frame bag who have no space left for bottle cages.
- Ultra-distance and gravel riders who want to drink on the move and carry extra water between refill points.
- Riders on remote routes who need more water capacity without adding bags.
