The side pocket swallows my 32oz canteen without bulging, and that extra strap is perfect for rolling up my yoga mat on the way to class. Everything stays cold for hours, even on a hot afternoon.

I've been carrying it to the farmer's market every Saturday, and the insulated interior actually keeps my groceries cool for hours. The exterior straps are genius too—my yoga mat fits perfectly without flopping around, and that 32oz canteen pocket is a lifesaver.

I was skeptical the 32oz canteen would actually fit in that side pocket, but it slides in perfectly and leaves room for my keys and phone. The insulated interior kept my lunch cold for a solid six hours on a hot day, and the yoga mat straps really do hold steady without slipping.
