The Zipper Tangent bikepacking bag is the answer for riders looking to max out the cargo potential of their frame’s main triangle, down to the very last square inch.
The Zipper Tangent is built from Cordura TPU—a material that is seriously abrasion-resistant. A thick internal TPU coating ensures the fabric itself remains fully and permanently waterproof.
Organization: The bag features two stash pockets for your small essentials:
✅ External Mesh: Located on the flip side—perfect for grabbing a quick snack on the fly.
✅ Internal: Tucked just below the main zipper.
Mounting system
We’ve equipped the entire contact edge with a daisy-chain loop system, letting you dial in the Velcro strap placement exactly where it suits your setup best.
The kit includes eight mounting straps lined with non-slip grip to keep the bag rock-steady and protect your frame.
Three of these are extra-long to handle the down tube (which is usually a bit beefier). If they’re too long for your rig, just trim the excess non-velcro end with scissors.
Water Resistance
The bag is sealed with a splash-proof zipper (with placement that you choose). Reflective logos on both sides keep you visible and safe when the sun goes down.
A Note on Water Resistance: Because this bag is constructed using a sewing process, the needle holes at the seams are not 100% sealed. This means the Zipper Tangent handles moisture and moderate rainfall like a champ, but it is not designed for full submersion or prolonged torrential downpours. We recommend tossing moisture-sensitive electronics in an extra dry sack just in case
⚠️ Frame Care Pro-Tip: Even though we use soft, non-slip materials, any bag strapped directly to a bike frame can eventually scuff the clear coat due to vibration and road grit (this applies to all brands, not just ours!). To keep your paint job looking fresh, we highly recommend applying some protective “helicopter tape” or frame protection film to your frame before mounting. This case is not just for our product but all frame pack you find in the market.
