Very pleased with this pack!!
I was hesitant and initially wanted to buy a similarly sized Osprey Raptor, but I'm glad I picked up this one instead!!
I use it for dayhikes and long road bike rides. What I love about this pack is that it's constructed in a manner that makes the storage space VERY versatile. It has three storage pockets + a bladder pocket + external pouch. The closed storage pockets include one large, one medium, and one small velour lined pocket. Inside the large pocket there is a small velour lined pocket and a skinny long pocket (fits my Topeak Road Morph G pump perfectly). The medium pocket has a separate webbed zip compartment inside of it.
Lots and lots of storage options to give you lots of flexibility.
Perfect for me. Versatile and just enough storage space while being very compact.
On road bikes, while down in aero position, the whistle on the chest strap can catch air and make a whistling noise... easily solved by a piece of tape.
The waist straps can be removed if you would like. For this size backpack, I prefer the thing waist strap OR nothing... one of the reasons I'm glad I took this over the Opsrey Raptor series and it's large padded (backpacking style) waist strap sides.
Love it, love it, love it!! The guys I ride with are jealous, and one of them ordered one to replace his CamelBak!!
