Great product.
The perfect size, seems strong and extremely light - as designed - and even looks very batman. Put together well and already using is for all kinds of tasks; climbing, Ikea trips, moving, laundry. Truly a bag of extreme utility, in sport and daily life, most people should have a big bag for their stuff, and this is the best I've found on the market. When folding it up, you can use the handle to wrap around and hold it together, this could be integrated into the design or the marketing and if you included a colour matching carabiner, this would hold the strap in place and be used to hang then bag above the ground in messy situations.
Great thing, and I think it should be marketed to the general public as an EDC utility object.
