Hydration Bags

Hydration bags carry more water than any bottle setup can — which matters on long mountain bike rides, extended gravel efforts, and any route where refill stops are few and far between. The Hydration Bags collection at RA Cycles covers seven packs from Salomon, Thule, and CamelBak, ranging from the slim 4L Thule Uptake for shorter efforts to the 12L version for full-day rides where you're also carrying tools, food, and extra layers. The Salomon ADV Skin 5 is a trail running vest that crosses over naturally to gravel and XC riding — lightweight, close-fitting, and built for moving fast. CamelBak's Octane LR is a dedicated running-style hydration pack with a 70oz. bladder. All are designed to stay stable while you're moving hard, so you can focus on the ride rather than managing your gear.

About Hydration Bags

Hydration bags solve the volume problem that bottles can't: on rides longer than two hours in the heat, or on routes without reliable water sources, a bladder pack is the difference between managing hydration and running short. They're especially useful for mountain biking and gravel riding, where you're often carrying tools and layers alongside water. The best ones fit close to the body to minimize movement, have easy bladder access for refills, and include enough organization to carry a pump, spare tube, snacks, and a phone without bulk that throws off your balance on technical terrain.

The seven packs in this collection come from Salomon, Thule, and CamelBak. The Thule Uptake series offers a clean, versatile range in 4L, 8L, and 12L capacities — sized for everything from quick trail rides to full-day adventures where you need meaningful storage alongside your water. The Salomon ADV Skin 5 is a trail running vest with a tight, bounce-free fit and soft flask pockets up front that translate well to fast XC and gravel riding. CamelBak's Octane LR is a running-focused pack with a 70oz. reservoir for riders who want maximum water capacity at minimal pack weight.

For on-bike hydration alternatives, explore water bottles and cages at RA Cycles, or browse saddle bags and top tube bags for carrying tools and essentials on longer rides.
