UPDATE: I completed my gravel race carrying two bottles and the USWE Outlander hydration pack!
- I didn't notice the additional weight, just over 1L of water with carb mix
- The pack sat high and tight, hardly moving even over some super rough gravel (I saw many ejected bottles)
- I did have to stop at the final feed station, as I needed one additional bottle of water
- I also stashed by phone in the pack to free up an additional jersey pocket
- On the last steep climb of the day I released the clasp to unzip my jersey when I got a little hot
- Really rate this pack thanks, a great recommendation!
