Why We Like The Down Shift 5L Hydration Hip Pack

Because our biggest Hydro Flask doesn't fit in our bike's bottle cage, we opt for the Down Shift 5L Hydration Hip Pack. Unsurprisingly, Hydro Flask incorporated their keep-it-cold tech into this pack and the included reservoir to keep our water insulated and ice-cold for up to three hours on the trail. On longer rides where the 50-ounce bladder isn't enough, the pack's two side pockets stash our smaller insulated bottles.


  • Trail-ready MTB hip pack for hydration in the saddle
  • Five-liter capacity with loads of space for tools, snacks, and more
  • Insulated hydration sleeve and reservoir keep water cold for hours

Great pack

I really like this pack. Holds just enough water for a 2-3 hr ride. 5-6 just walking/hiking. Has enough pockets to hold some tools, car keys, cell phone.

The best!!!!

I love my Hydroflask hip hydration pack. I've wrestled with my last camelback leaking. The slide closure is so easy and absolutely no leaking plus it's insulated to keep my water cold. It's easy to fill and the pack has places to hold extra water bottles and your phone and snacks I couldn't be happier.
