Kask is better known for making track helmets, but it has just released a new trail helmet called the Rex.

It sports a more rounded profile than most — a bit like an Urge helmet — but the rear does extend right down to provide maximum protection.

The Octo Fit retention device has a massive range of height adjustment, so really cradles the back of the head. This works so well that the helmet hardly moves, even without the chinstrap buckled up.

Also, on the back of the helmet is a clip for a goggle strap, and like most modern trail helmets, you can park goggles beneath the peak. Unfortunately, the peak is the worst thing about the helmet. It’s adjustable, but only in two positions — the first is too low and the second is too high.

Webbing straps fit snugly round the ear, and the Eco chinstrap is made from soft leather. Plush, Coolmax internal padding and gel pads reduce hot spots, while still absorbing sweat. I’d only describe the venting as average, but at 325g the Rex is a competitive weight.

In terms of fit and comfort, the Rex is up there with some of the best helmets. Unfortunately, the limited visor adjustment and meaty price tag counts against it.
