I've used the pack on a few hikes, with 2L water bladder, and it works great! I also use it as a bike commuting pack daily and the helmet clip is wonderful. Lightweight, back breaths nicely (but I'm also not a very sweaty guy), but after a hilly Seattle bike commute, my back is wet as expected though. Chest pocket is useless for a phone, but does just barely fit my sunglasses in it.
Pros: -Detachable rain cover (also it's neon yellow/green which is nice for visibility purposes)
- Helmet clip
- Protected sunglass/phone pocket
- Main compartment fits everything I need ( 32oz water bottle, which also fits in the side mesh pockets, bike pump, extra layers, lunch for work)
- Secondary pocket is nice for smaller things, organizer for keys/wallet/hex wrench and more.
Cons: - Would have liked the back support to be a little more sturdy (I was torn between buying this pack and the comparable sized Manta AG, but got this pack for half of the price and it is definitely worth getting a little hotter for half the price)
- Chest pocket functionality is minimal
