This Yoga mat renders the popular catchphrase “they see me rollin” obsolete. Designed with technology borrowed and refined from a child’s slap-on wrist band, the stay flat when you need them to, and automatically (automagically) roll up neatly when you’re done! It isn’t as simple as it looks however, say founders Aaron and Yu. They spent several months refining the process till they got it to work like a charm. The result? Bloody impressive! The mat stays absolutely flat when you need it, never dog-earing or folding over and being an annoyance while you’re meditating, exercising, or dancing. Do what you gotta do, and then just flip the mat over and it autonomously rolls up (akin to a yo-yo, hence the name) into a neat little roll that’ll never roll crooked, thanks to its dual rolling band arrangement… which you can then pick up and carry home or dump in the boot of your car! Now if only they made some self-tucking bedsheets… Designers: Aaron Thornton & Yu Tsai.
