When riding I almost always carry a Deuter Race Air Lite hydration pack (photo) containing stuff I may need during the ride. I’ve had the bag for less than a year and recently a leak developed at the bottom of the bladder, right at the base of the outlet’s weld. Deuter bags carry a lifetime warranty, so I submitted a warranty request.
A few days later I had a new bladder in my possession, and instead of sending the old one back Deuter just asked for a photo of the bladder and where it’s leaking. That’s what can be seen above. This leak wasn’t huge, but it was enough that with each ride the bottom of my bag would be wet, occasionally dripping on me. I was more concerned that it would grow, resulting in an unexpected failure leaving me stuck without water.
I’ve been really happy with the Deuter pack thus far, and good warranty support when it failed was a nice bonus.
