Say goodbye to old-school casts for broken bones. Exos Medical's braces, splints and casts are adjustable, breathable, lightweight, clean and waterproof. The only drawback is that you can't have girls sign them.

These things use a lattice of thin steel laces that can be tightened with one hand and loosened using a clicky dial knob. You can set it once and leave it be, or you can continually adjust it for the best fit. The best part? You don't need a damned saw to get the thing off. [Exos Medical via Fast Company]
