Outdoor Products Cyclone Hydration Pack

Good design. Leaky valve.Disappointing

Easy to refill with wide opening. Can be used alone on attached to an internal or external frame pack.

Excellent product. I had to learn to be carful to get the lid sealled correctly but it has worked great. The evening the pack arrived I cleaned the bladder according to the instructions. The next day I wore it on an extended wilderness search and rescue operation. WIth long rough hikes. Worked great. We found the lost man, too. I have also worn it for 4 days of urban bike patrols. Enough insulation to keep the water cool in 90 + degree days. And I've only had the pack 10 days.

I bought two of these for me and my girlfriend; we used the bladder separately and BOTH bladders leaked. I am returning them immediately.

I did not buy this product from Sierra Trading Post. However, it was exactly what I was looking for in a hydration pack. No bells or whistles. Problem is, the valve leaks, the strap has torn, and anything that goes into the bag with the bladder gets soaked. As an asthmatic, I need to carry my inhaler, and it's always a good idea to have ID on hand, and keys. I can't find a replacement valve anywhere! The bag is quite comfortable for me, though, and I have worn it hiking and biking. I'm sure that my toddler chewing on the valve didn't help, but it IS a BITE valve. I've not ever had this problem with Platypus bladders (and their valves are easily replaceable). Alas, though the bag fits well, its job is to hold water and a few necessities, and it drips all over the place and can't hold anything but the bladder.
