When you're on a trail run with a minimal amount of gear, the awardwinning North Face Thresher Hydration Backpack keeps things lowprofile. The X-bungee system is perfect to stash a windbreaker, while a removable, adjustable waist belt gives you options for lighter loads. The 70oz Nalgene antimicrobial reservoir prevents mysterious organisms from camping out in the bladder, as the magnetic bite valve stays close for at ready liquid relief. A secondary compartment allows for lightweight necessities, while a reflective light loop and reflective hits keep you in view at dark.
Small Backpack
The backpack is very small. Great for short hikes or bike rides.
Don't buy it - wish I had a review when I did
Leaks like nobody's business - all down your back. The connection between the hose and bladder is very poor. Also, the mouthpiece leaks all over your shirt/pants while riding, even if it is closed. Not to mention there is a hole in the bladder hose now from normal use. It'll work fine - just never take the hose off of the bladder or use the mouthpiece.
