Submitted by James a Cross Country Rider from College Station, TX
Date Reviewed: March 22, 2007
Favorite Trail:Bar H in St. Jo, TX. Although I'm a Lake Bryan local.
Duration Product Used:Less than 1 month
Price Paid: $60.00
Purchased At:BCS Bicycles
Strengths:Lots of storage space with a hook & pocket for keys/phone.
Easy to fill/clean bladder.
Air channel really makes a difference.
Easy to use locking mechanism on bite valve.
Weaknesses:The elastic on the pocket doesn't make it too secure.
Bite valve seemed to leak a bit.
With full bladder, the storage space suffers.
Similar Products Used:Camelbaks and also a Trek hydration pack (demo from a Trek shop I worked at)
Bike Setup:Trek 7000 - very little of it is still stock. Truvativ Stylo 3.3 GXP cranks, Mavic EX721 wheels (I know they're FR-oriented, but I got a great deal and I needed a new set), LX shifters, XT mechs
Bottom Line:I wanted to try Hydrapak so I gambled on the AS Trail. I am very glad that I did. The bladder doesn't have a screw-on lid like most other systems but rather a roll-top with velcro. I know that sounds bad and I was skeptical, but it really does hold water well. I filled it up and squeezed and couldn't get it to leak. Additionally, the bladder is easily pulled inside-out so that makes drying and cleaning a breeze. Oh yeah, the hose disconnects from the bladder so you can take the bladder out without snaking the hose through the system - the connection is also excellent, no leaks.

The construction of the pack is perfect. Nothing is coming apart, no loose threads. The straps stay tight. I did find that the chest strap (I didn't even try to use to waist strap) kept pulling my jersey up exposing my lower back to mud - a problem made worse, I suspect, by the air channel pads. But when I disconnected that strap everything was fine. The pack has a curved rigid side that works in tandem with four pads to keep contact at a minimum and keep air flowing over your back. This worked great - even in high Central Texas humidity after a period of heavy rain.

The pack has lots of storage space - nearly as much storage space as water space. I would like to see some sort of expandable system for the gear compartment. If you fill the bladder up, things get pretty cramped. The gear compartment has a pocket to keep some things available/safe and has a little clip so they stay put. The elastic on this pocket could stand to be a little tighter so it holds the pocket closed. Not a big deal and it hsan't been an issue for me. This is also a cord-port so you can run headphones or headlamp cables from the pack. Good feature although I don't really take advantage of it.

The bite valve may be the only real problem the system has. It's a very simple system and gives water readily. Once I got used to how the valve acted, it wasn't too bad. Part of my problem may have been that I'm used to a straight valve and this one was a L-bend. Probably not going to be an issue for others. The valve's tendency to premature hydration is the only thing holding this pack from 5 chillis overall.

Plenty of room for rides of a few hours. Elastic cords to hold jackets and such. Great deal for any sort of rider.
