Can't put to much rating into how good the bag is. I brought it from the shop and found a cheaper KINGS bag that was the same size but waterproof. So i returned this bag.

Good sized bag (Bigger than I thought when ordering) - functional strap system and good zipper with velcro overlay to prevent water ingress.

Great size; easy to attach. Small tear after first trip. Some moisture issue inside the bag, despite minimal rain.
