Triangle Frame Bag in PU and EVA
A moulded triangle bag with a side pocket on a one-way waterproof zip
What It Is and Who It Is For
A frame triangle bag made from PU and EVA with a 210D nylon inner liner, sewn construction, hook-and-loop frame straps and a side storage pocket closed by a one-way waterproof zip. It measures 25 by 22 by 6 cm and weighs 180 grams.

Why Buyers Choose This Part
Moulded PU and EVA shell
Holds its triangle shape whether it is full or nearly empty, which soft-sided bags do not.
Separate side pocket
A second compartment on its own one-way waterproof zip, for the things you reach for without stopping.
25 by 22 cm at 180 grams
Mid-size: more capacity than a top tube bag and easier to fit than a full frame bag.
Problems It Solves
- Soft frame bags collapse and everything ends up at the bottom
- One large compartment means digging for keys at a junction
- Fabric bags soak through at the point where they touch the frame
Who It Is For
- Commuters who want a structured bag that holds its shape
- Riders who want separated storage rather than one big pocket
- Brands offering a mid-size frame bag
Application Scenarios
- Daily commuting
- Day rides carrying tools, a layer and food
- City bikes where the bag stays on permanently

Compared With the Alternatives
Against the Waterproof Triangle Bag this is sewn rather than welded, so it is weather resistant rather than sealed, and it holds less. What it gives you is a rigid moulded shell and a separate side pocket.
Customisation and Manufacturing
Sewn luggage is the most flexible part of the catalogue to customise, because the pattern, the shell face, the lining and the hardware are all separable decisions. Woven labels and printed panels both work here.
- Woven label, printed panel or embossed shell face
- Shell colour and texture changed at material stage
- Zip, buckle and strap hardware specified separately
- Retail packing with your own barcodes
Fitting and Living With It
Step 1
Strap to the top tube and down tube, pulling the straps tight so the bag does not rock out of the triangle.
Step 2
Use the side pocket for keys and a phone so you are not opening the main compartment at traffic lights.
Step 3
Check knee clearance on a small frame before committing to it.
Step 4
Wipe the shell clean. The PU face does not need proofing.
