The Atlas Original neck brace is put on and removed by sliding it over your head. If you have a crash and it needs to come off without going over your head, a split-pin pulls out and a simple threaded nut is undone to release the brace.
Once the brace is on (which can be a squeeze for riders with larger heads) it’s surprisingly comfortable. It stayed in place well when we were riding, thanks to the super sticky, rubbery padding.
The all-round flexibility of the brace is noticeable too, with evident expansion when we were breathing deeply, and no upwards or downwards movement, although one tester felt a bit of discomfort with pressure on the inside of the collarbone. There’s no noticeable restriction when wearing a helmet – even bigger motocross-style lids.
The fact that the brace is available in three adjustable sizes is impressive too.
