- Micro-dial can self-loosen
The Kask Rex’s pads are thick and made of Coolmax which do a better-than-average job of soaking up sweat to mitigate it running down the cyclist’s face or into their eyes. In addition to Coolmax, the pads are also antibacterial and antimicrobial. They are removable and washable and dry faster. One tester said after wearing the Kask Rex on a 23-mile ride in humid weather, he was a Coolmax padding convert. Another tester declared that the padding was the most comfortable that he has experienced and even after several long rides in excess of 15 miles, he did not experience any pressure points or discomfort. However, the leather chin strap took some getting used to.
The Kask Rex’s 20 large air vents and internal channeling do an excellent job of promoting air flow. One tester who tested multiple medium-sized helmets in the test felt that the Rex had the highest degree of ventilation. Its enhanced ventilation is augmented with beefy antibacterial, antimicrobial sanitized Coolmax padding that maximizes sweat evaporation and dry-time. Of all the size medium helmets, all testers agreed that they never experienced sweat dripping into eyes or onto faces while riding.
The Kask Rex size medium measures fifteen inches from ear to ear and seventeen inches from front to back for outstanding head coverage.
A fully-adjustable ratcheting visor is removable, making it ideal for wearing goggles. When set at the highest positions, goggles can be perched off the face on the front rim of the helmet. The Rex’s goggle-friendliness is topped off with an integrated and removable goggle retention clip in back. At 3.25 inches in length, the visor offers the most sun-shielding of all the helmets in the test. However testers agreed that when all the way down, it can interfere with visibility on ascents or in an aggressive riding position. They mitigated this by simply raising the visor slightly.
On top of the helmet is an integrated mount for an action camera or lights.
One of the most unique features of the Kask Rex is its chinstrap. Instead of the normal webbing, the Rex offers an eco-leather chinstrap. While it is washable, one tester said that it felt weird and took some getting used to.
The Kask Rex’s Octo Fit system allows an impressive degree of adjustability. A glove-friendly rubberized micro-dial adjusts both the height and the width up to 180 degrees via an internal ratcheting strap. This allows it to accommodate a wide range of skull shapes and vary the helmet’s pitch on the head. One tester mentioned that the micro-dial tended to loosen on its own. Still, it was easily re-tightened on the fly.
However, the side straps are not easy to adjust. One tester compared it to a competitor’s Tri-Fix web splitter, which sits below the ear lobes and spreads the two upper lengths of webbing into a wide U-shape around the ears (instead of a standard V-shape). One tester found that he didn’t like the slack that could never be tightened. Another tester said it didn’t bother him.
Despite its generous head coverage, sturdy straps and a leather chin strap, the Kask Rex on the lighter side of the size medium helmets weighing in at 12 ounces (341g).Continue Reading
