#1 — Fox Racing Proframe RS MIPS Helmet | GearScore: 90.50/100 🏆 Platinum

The Fox Racing Proframe RS MIPS has earned its place as the most recommended full-face enduro helmet on r/MTB in 2025, and it's easy to see why. The combination of a MIPS liner system and Koroyd impact material delivers a genuinely confidence-inspiring level of protection without the claustrophobic weight penalty of traditional full-face helmets. The removable chin bar is the headline feature here — pedal climbs and mellow flow trails no longer require swapping helmets, making this a true one-helmet quiver for enduro athletes. Ventilation is exceptional for a full-face design, keeping heat buildup in check even on long, punchy climbs.

Range to Reef Take: If you ride enduro, shuttle laps, or any terrain where a chin bar could save your teeth, the Proframe RS MIPS is the smartest single investment you can make in your riding kit. The modular design alone justifies the price of entry.

#2 — Smith Network MIPS Bike Helmet | GearScore: 90.00/100 Platinum

Smith's Network MIPS lands at the top of the open-face category with a Platinum GearScore that reflects both its protective credentials and its refined fit system. Built around Smith's Koroyd construction and paired with MIPS rotational protection, it addresses both linear and angled impact forces — the kind of hits you actually take on the trail. The dial-adjust retention system keeps the helmet locked in position whether you're sprinting a fireroad or wrestling through rock gardens. For all-mountain riders who don't need a chin bar but refuse to compromise on protection, the Network MIPS sets the benchmark.

Range to Reef Take: The Smith Network MIPS is the open-face helmet we'd reach for on any ride that doesn't demand full-face coverage. It earns its Platinum rating honestly and sits comfortably at the top of its segment.

#3 — Smith Engage MIPS Bike Helmet | GearScore: 88.00/100 Gold

The Smith Engage MIPS brings serious protection into a package that appeals to riders who want a trail-ready helmet without crossing into the premium price tier. MIPS integration is standard, and Smith's fit architecture keeps the helmet stable across a range of head shapes without excessive pressure points. It's a versatile performer that handles everything from cross-country laps to more aggressive trail riding with equal composure. Riders stepping up from entry-level lids will notice the difference in both fit quality and impact confidence immediately.

Range to Reef Take: The Engage MIPS is a Gold-tier performer that punches above its price point. A smart pick for riders who want Smith's protection pedigree without paying for features they won't use.

Giro Manifest Spherical | GearScore: 88.00/100 Gold The Giro Manifest Spherical uses Giro's Spherical Technology — a ball-and-socket MIPS integration — to deliver smooth rotational protection in a well-ventilated, trail-ready package. It's a strong alternative at the Gold tier for riders who prefer Giro's fit system over Smith's.

Smith Mainline MIPS Bike Helmet | GearScore: 88.00/100 Gold The Mainline MIPS is Smith's dedicated downhill and bike park helmet, offering full-face coverage with the brand's trusted Koroyd-and-MIPS protection stack. If you're spending more time at the lift than on the pedals, this is the Gold-tier choice to consider.

Smith Persist MIPS Bike Helmet | GearScore: 87.00/100 Gold The Persist MIPS delivers core MIPS protection and solid build quality at the most accessible price point in this lineup. It's the right call for newer trail riders or those seeking a reliable backup helmet without stretching the budget.

Quick Buying Guide

1. Protection System

Look for MIPS or equivalent rotational impact technology as a baseline requirement — linear foam alone is no longer sufficient for the impact angles mountain biking produces. Koroyd, WaveCel, and Spherical Technology are all legitimate upgrades worth paying for.

2. Full-Face vs. Open-Face vs. Convertible

Match the helmet to your terrain. Downhill and enduro riders should seriously evaluate full-face or convertible designs like the Proframe RS. XC and trail riders can typically run open-face without compromising safety on their normal terrain.

3. Fit and Retention System

A helmet that moves on impact is a helmet that's failing its job. Prioritize models with tool-free dial retention systems and multiple size options. If possible, try before you buy — head shape variation is significant and no fit system compensates for the wrong size shell.

Final Verdict

The Fox Racing Proframe RS MIPS is the clear top pick of 2026 with a GearScore of 90.50 and a design that genuinely solves the full-face-vs-open-face dilemma that enduro riders have wrestled with for years. For open-face riders, the Smith Network MIPS at 90.00 is the Platinum-tier choice that earns every point of its rating. Whatever your discipline, this list covers every type of mountain biker — the only wrong move is riding without a quality lid.
