Poor quality and service


I had great hopes for this product as it has some cool features like the magnetic hose tube, and a nice mesh front pocked. However, I would never buy another Thule bag again, within 2 rides the first mouth piece was broke and had to be replaced. Recently I went to pick up the bag after a break and it snagged a branch and ripped a hole in the front mesh pocket, Thule could do nothing to help. If this were a commuting bag or day pack I could accept this, but they promote it as a biking bag so it should be able to take a little bit of expected exposure to elements. I know for a fact that Osprey packs have been replaced for much less than this, and that is what I will buy again next time. Thule has some fluffy features but the build quality is not there.




Much improved over my camelbak


Love how it feels & it's easy to adjust straps. Holds a lot of water and the hose design is great. Highly recommend.

Best hydration pack I've ever had


This is hands down the best hydration pack I've used. I've been using this pack for 2 years and it remains my go-to pack while others collect dust. It's thoughtfully designed for the needs of mountain biking - The pack sits lower to distribute the load over the hips (vs. up high on the shoulders) which reduces fatigue on long rides. The expandable cargo capacity combined with the 2.5L reservoir makes this pack extremely versatile for shorter rides to full-day efforts. The ReTract hose system works flawlessly for staying hydrated while keeping the hose secure and out of the way. Easy access side pockets makes reaching for food or gear a breeze while riding. Various internal pockets for organizing and securing gear. The materials are durable and allow for good ventilation. This pack is holding up well and I'm looking forward many more miles. Highly recommended!
