I think the pack is tremendous!

“It’s the first pack I’ve had that really does what it is supposed to. I had back surgery six years ago. Part of a disc in my back was removed. I don’t have any back pain with my pack as I always had with other packs. Backpacking is the love of my life. I have had one of the best known, highly rated and most expensive internal frame packs on the market. This one surpasses that in terms of comfort. There was no discomfort in either the shoulders or the hips.”
