Nice, quality backpack. We love the portion control food pack.  However, bought for my husband,  who is 6 foot, 245 and it looks ridiculous on him.....it is small.....like undersized backpack.  For $129 we expected a bigger backpack.  I suppose our fault for not reading specs closer. We saw details of enclosed food storage etc and figures proportioned would work. We were wrong.  Hubs have to our fitness oriented teenage daughter.  It is her size. She loves it.  We will get next size up bag for him.
