Lightest

The Speed wins big points for its lightweight construction and comfortable fit. With a simple buckle and single dial in back, the helmet is easy to adjust, even with big mitts on, although testers did find its boxier cut better suited for bigger heads. (Regardless, hoods slid over this helmet just fine.) Best to try this one on before purchasing it—one tester climbing in Montana’s Hyalite Canyon found that the adjustment design created pressure on his forehead. Testers were torn on the bright green and gray design. Some thought it was cool, while one tester said the helmet looked like it had been slashed by a grizzly bear.
Instead of being fully covered in the standard light, plastic shell, the Speed’s outer surface is a combination of thin, bright-green plastic and dark gray foam. This definitely saves weight (the helmet is just 7.4 ounces), but it also means the helmet is more vulnerable to wear and tear. Even after just a few days of testing, this helmet was already showing some dings, and it isn’t recommended for those that severely abuse their gear.
