We use highly waterproof Hypalon and Ripstop Nylon materials and employ a welded construction technique to ensure zero water ingress. Custom water-resistant zips with protective zip garages prevent almost all water from getting in when the zip is fully closed, and the puller is in the garage; however, in the heaviest downpour, we cannot guarantee they won’t let water in. We recommend keeping your electronics in ziplock bags.

Yes, we supply 2 x 18.5cm Cargo straps and 1 x 14.5cm Cargo strap.

However, if you are unsure, we recommend using the Long Top Tube bag on its own.

Not the 3l and 2.2l, but they will fit with the 1.6l Long Top Tube Bag if you have more than 575mm of space on your Top Tube. Alternatively, they will work well with one of our short or standard-length Top Tube Bags.

As we offer a wide range of Frame Bag sizes, it is challenging to provide a definitive yes or no answer. You can use our printable templates here and compare them against your frame to see if the mounts will align.
