Customer Reviews

Comments: Found the product to be perfect for runs under 15 miles. Hold enough, with out carrying to much. The cap is a bit difficult to get on, to avoid minor leaking as many sports bottles are. When used with UltrAspire vest no need to take bottle out to drink. Works very well in the regards. Sloshing sounds can be annoying, as to the straw hitting against your body as you run, but a good compromise for how the system works over all. Great for 10-15 mile runs when larger water supple is not needed.
