It is waterproof and very good for using on my bike in wet weather as it dry quickly and keeps all the things inside the Pannier bag dry, It comes with a strong handle with is very useful, and has to top strap to clip the Pannier down at the top and also 2 side straps for added security on this Pannier.

However theyve banged against my breaks alot causing a repair to be needed, a way around this problemnis ive bough for £6 some adhesive stoppers that are ment to be for the back of a headboard on a bed (stop headboard banging the wall) whilst its made them a little more awkward to put on the bike its kept them away from my breaks. If they designed them with zip away straps to anable you to put them on your bike whilst out, if they need removing from your bike would be an amaizing addition because they are awkward to carry. All in all though they are easy to use, great quality, decent size and waterproof well worth paying the extra for. ## Frequently Bought Together - ROCKBROS Bike Pannier Bag 25L-32L 100% Waterproof Rear Rack Bicycle Bag for Rear Carrier Bike Handbag for Cycling Touring Travelling - ROCKBROS Bicycle Pannier Rack Mountain Bike Pannier Rack Quick Release with Reflector 24-29 Inch With/without Mudguard Aluminium Alloy --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/499323897-bike-rear-rack-bag](https://www.desertcart.co.uk/products/499323897-bike-rear-rack-bag) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-23*
