Just wow!!!

Phenomenal bag. My first ever Osprey bag and it comes with a 2.5L hydration pack. It's lightweight, holds far much more than what you actually think you need and has pockets for loads of tools just like your mini tyre pump.

Osprey never disappoint

My third osprey bag, this is packed with really well though out features. The bladder is well integrated into the pack without being difficult to refill, and the pockets are just the right size for a days riding. Looking forward to using it on the trails and as a day pack when hiking. Plus go outdoors beat the price it was offered at on all the other online retailers!

Just right for the job

This is a great little pack and well worth the money.
The build quality is excellent and so is the attention to detail, it has two little mesh pockets inside the front pocket, perfect for storing my allen, and torx wrenches, along with a little plastic carabiner for your car keys - which I love because I was always paranoid about losing my car keys when I'm out mountain biking.
The built in hydration pack is great for mountain biking, and the magnetic clip is strong and very convenient.
It's so light and small you forget you have it on, it's the perfect size for carrying a few tools, a spare inner tube, a flapjack, etc.
I would definitely recommend this as a hiking day pack or trail riding pack.
