Awesome short distance pack
I really like the pack and have used it for several races of 10 miles or less. It doesn't move too much, is comfortable and I like not having to use a handheld. The shoulder pocket is nice for having some pre or post race fuel handy. The flask is easy to access and refill at an aid station. My only issue is with the bite valve not staying under the cover like it is advertised to do. The straw is too short for this to work properly and it only gets worse as the flask becomes empty and sinks into the pocket. It's not an issue for me when I'm racing road or trail but I was hoping to use this pack for OCR as advertised but don't see that happening since the bite valve won't stay under the cover. Overall, it's an awesome pack that I have used many times and will continue to use for short, hot runs. I would give it 5 stars if it worked as advertised.
