LIV Rail Helmet Review
With a wider fit range for a more secure fit, designed with long-hair in mind, and with increased protection through MIPS technology, the Rail is Liv’s most high-performing off-road helmet yet.
Out of the box, I just loved how the Liv Rail Helmet looked. The sleek aesthetic with the matte+gloss finish caught my eye immediately. When I threw it on my head to check the fit, I noticed its lightweight design. The MIPS Air Node liner technology keeps my hair from getting wrapped around the nodes and velcro (most of the time) but throughout the test rides, my hair got caught significantly less than all other helmets I’ve worn.
MIPS Helmet

Liv Cycling is known for their commitment to quality. With the Liv Rail MIPS helmet, they’ve raised the bar even higher. Safety takes the center stage with the incorporation of MIPS technology, minimizing rotational impact. The in-molded upper, sub, and lower PC shells create a 3-layer system crucial for mountain and off-road biking.
Independent helmet safety testers gave the helmet a 5-star rating from Virginia Tech and ranked it #44 out of 206 helmets. The MIPS liner also contributes to the helmet’s impressively lightweight design without compromising protection. You can read more about the MIPS Air Node Technology here.
Ventilation

Ventilation is paramount in any mountain bike helmet, and the Liv Rail MIPS doesn’t disappoint. With 20 generously sized vents, this helmet ensures you stay cool and comfortable, even during the most intense rides. Plus, the adjustable visor is a thoughtful addition, allowing you to tailor your level of sun and dirt protection on the fly. The visor is also ‘moto-style’ and flexible, adjusting to three positions allowing for stowing goggles or using the broad top surface for a camera or light attachments.
Sizes

● S (51-55cm)
● M (55-59cm)
The Live Rail MIPS has two sizes: Small (51-55cm) and Medium (55-59cm). The helmet boasts a 4-position vertical fit system and snap-in rear height adjustment fit system, ensuring a snug and secure fit for riders of all head shapes. Like most helmets, the retention system can be tightened using a dial on the back of the helmet.
Pony Tail Friendly Design

And for those with longer hair, the Liv Rail MIPS has got you covered with its ponytail-friendly design. I am one such rider, and although I appreciate the design effort, I typically find it difficult to position my ponytail in just the right position to fit through the slot without affecting the angle of the helmet – but hey, that’s my problem, not yours. I love these magnetic Fidlock ® Buckle Systems for easy on and off even with gloves on. Once fitted, the chin strap is fairly long but the excess slips into a small rubber tab and stays in place.
