Great protection AND comfort
I've tried different types of wrist guards before, all of which were advertised as 'under the glove' versions, and none were as comfortable as Impact. I wouldn't even use other brands, because of the discomfort and limited range of movement. Impacts are by far the most comfortable. I even forget I'm wearing them. They also provide great protection. I've taken some hard spills with no harm to my wrists.
Broken wrists are the most common snowboarding injury. Do yourself a favor and get a pair of Impact wrist guards.
