This is a great Backpack. It arrived swiftly first of all and was all packaged very nicely. When you open the packaging the first thing you will notice is that this has a lot of straps, this is good because nearly everything on this bag is adjustable for that perfect fit but the straps might be slightly annoying because there are a lot. The 2 side pouches are held on with very strong velcro and won't fall off, they are also attached with a strap behind the pouch just to make sure. The inside of the bag is lined with waterproof material and it can be fastened at the top, this added with the rain cover makes it very waterproof. There are plenty of pockets and loops for extra little things you need to carry. The one little niggle I have is that there are no instructions so figuring out some of the adjustments, especially the one for the side supports are quite tricky to figure out, but once thats done its pretty easy. Overall this is a great bit of kit; comfy, decent size, good adjustment and waterproof.
