This was not the pack that I originally set out to buy, or the amount I was looking to spend, but after trying various packs from different brands, this one stood out by some way. It was a good fit off the shelf and easily adjustable.
With a wide range of features on a pack like this, there will always be some that you find useful and some deemed no more than a bit of a "gimmick, and will divide opinion. However, personally, I found that top pocket swallows a load of gear, and on a longer backpacking trip, the fact that it floats is a bonus when packing extra gear. The two small pockets on the hip belt come in handy for holding trail snacks and a small camera. Most packs these days are hydration compatible, and the external compartment swallowed my Camelbak with ease.
After a week in the Lake District carrying a full load, this proved to be an extremely comfortable bag. The hip belt adjusts easily and after a while molds itself to your back, giving you the perfect fit. This can be done in store but after a few hours of use, it sorts itself out. Fine adjustments to the shoulder straps enable you to pull the load in tight, or loosen it off, dependent on the terrain and the side compression straps keep everything tight. The back-mesh system won't keep your back completely dry, as you'll always perspire when carrying a load, but it is comfortable and better than other bags I've used.
There was a minor problem with the stitching which pulled away slightly, but cannot fault the Customer Service from the excellent staff at the Watford branch, who exchanged the bag without any fuss.
All in all this is a very comfortable pack to carry and despite the minor issue with the stitching mentioned above, I am very happy with the purchase.
