Really good, I really like all the Compressport bags. Stay well in place when running nothing bouncing around In the pockets.

On paper it's a great product: super light, adapts to body and really clean design, but in use there were clear issues: (1) lightweight material just doesn't last; only bought mine a year ago and already there is a massive tear in main compartment - accept that it could be my fault because I did stuff the pack very full, but certainly don't expect a durable pack if looking at this pack. (2) Bouncing was very noticeable, especially when you have filled water bottles - and they're not easy to get back in once you take them out. (3) In terms of pricing, it's definitely up there for something that won't last very long should you be someone who uses your vest frequently. I liked the number of pockets that are within reach on the go, the cinching options and the zip is surprisingly stable, but I'll be looking at other options for my next pack

Great running vest for taking all you need. I did have reservations, but having done some thorough research into all types of vests, and not to mention Sebastien was / is my idol growing up as a trail runner, I decided to go for this vest. The zip was my first reservation, but so far it's held up really well and believe it does a better job in making the vest pack really stable and secure (didn't notice any bouncing). The second reservation was about the material and whether it would bounce around too much when loaded, but such has been the quality of materials and design, I've hardly noticed any issues with this. I love that it's so light, forms to your body and has enough capacity to take everything you "need" on a run. It's obviously designed to take the essentials, and for me that's perfect - try to avoid taking non-essentials / luxury items. It's a bit early to give a comprehensive review given I've only used it a few times (mostly loaded with one soft flask, energy bars and couple bits of clothing), but so far so good.
