Excellent product. Used in London to Brighton bike ride and was excellent to keep fluid up and pack essentials in bag keeping it lightweight and compact. Highly recommend.
Good for storage but bad for drinking
Used for 1 week or less
Brought this today as I have just started riding the trails and it's seems easier than reaching for a bottle. Tested at home before I took it out, no problems, great storage for my spare tube, multi tool, pump, phone and keys. Felt comfortable and secure so 3 hours after purchase off I went but ten minutes into my ride I went for a drink and the blue part had disappeared on the trail. Could still use if I continually opened and closed the value but made it awkward to drink on the go which defeats the purpose so now I need to go and purchase a new bite valve.
Response of the brand
Sorry to read that the valve came off mid ride. You local store will help you with a replacement. If the valve was defective, they will issue you with a new one.

Good quality ruck sack and bladed pack
Finally a hydratation pack that I love.
Used for 1 week or less
I'm not normally one to reviews things without someone asking me to.. But I bought this today for running. I use a bigger pack when I ride and had a previous running pack that I never got on with from one of the leading brands in the field. They always slip about to much... Finally this one is what I've been looking for. I love the way it fastens. Its a much better fit for bigger breasted woman as it fastens snugly in the centre, over the top of your chest. Its is (almost) perfect and I can't wait to head back out again tomorrow to use it. Which is good because it was motivation to get me running again!! You really should put some of these in the running isle.
