This bag has the best support of any small day bag I’ve worn. The straps are done a little differently and each one pulls exactly where it’s needed. This is the bag for carrying a bunch of bulky gear that would normally poke me in the back. Stuff like my camera, binoculars, lights, this bag carries whatever without me noticing any weird lumpiness. It can be tightened so the contents aren’t shaken over a bumpy road. Every feature is designed with intention and works as intended. The back pad is stiff no matter what, so this bag feels consistent regardless how it’s packed. My one complaint would be the depth, it doesn’t expand a whole lot, even fully loose. The elastic on the front is the perfect size for a 40oz Hydroflask and the flaps keep it from falling loose. I think this must be the most effective bungee on a bag front I’ve used to handle a full bottle like that.All the materials and components are nice. Nothing is skimped for a lesser version. The zippers pull smoothly. Extra durable. Light for how sturdy and supportive it is. Keeps my gear dry thru the rain.
