Why We Like The Rex Helmet

Like a T-Rex crashing its way through the forest after an elusive snack of prey, bomber enduro runs often mean tarrying on the ragged edge and within millimeters of any number of obstacles that may or may not yield when you hit them. The new Kask Rex Helmet is there to help protect your dome through it all so you come out of it with a clear mind, a bit of adrenaline, and a few scratches for future battle scar comparisons — dinosaur bites notwithstanding.

The Rex features Kask's MIT technology, which is found in all its helmet offerings and includes a polycarbonate layer covering the shell at the top of the helmet, along the base ring, and across the back for claims of improved safety and protection compared to helmets without this layer. Kask uses an in-mold process to fuse the inner, extruded polystyrene layer to the polycarbonate shell for excellent structural integrity and shock absorption. Inside the helmet, the plush Coolmax padding sitting comfortably against your noggin is removable and washable for long-term, stink-free use.

Borrowing from Kask's road line of helmets, the Rex's chinstrap is fashioned from easy to clean eco-leather for a unique pop of functional style. An adjustable visor protects your forehead from branches and debris, and doubles as a convenient shelf for goggles during shady stretches and long climbs. The Rex features a strap retainer on the back of the helmet for additional goggle security, and an integrated action camera mount makes documenting the adventure a breeze.

Superior helmet with the top of line protection. The retention system will fit almost every head shape and is definitely secure. The helmet is now ranked number 1 in safety.

Nice helmet but not great w/ sunglasses

I returned this product before using it
Size Bought:

This helmet fits really well, similar fit to the POC Tectal & Kortal, but a bit smaller on the head. It looks good (though I prefer the POC look still), and the GoPro mount doesn't look too bad. The reason I counted this one out is because of the back of the helmet retention system interferes with Oakley sunglasses. Also, I thought the retention could potentially be uncomfortable on rides. Due to sunglasses issues, it was an automatic no in my book. If you're wearing goggles, this system shouldn't be an issue. On the plus side, the retention system glues it to your head and will make it not move.
