I have been using this chair for the last four years while riding the bus. Got it because there is not always a dry place to sit at bus stops. I couple this chair with a large umbrella and I am good to go. Won't fit in a standard size back pack, but after a few adjustments to the strap go it to work.
The northwest territory quad stool has good build. It's easy and relatively light to carry around. I do wish it was even lightly and the legs were slightly shorter so I could fit this into a standard backpack.
Got this for a camping trip. Wanted to have something to sit down on that was smaller and lighter than a portable chair. Weighs less than three pounds so easy to carry around in my backpack while hiking.
