Best Full-Face MTB Helmets 2026 for Adults & Youth: Fox Proframe vs Leatt Gravity vs Fox Rampage

The best full-face MTB helmet depends on where you ride. For enduro and long days with climbing, the Fox Proframe RS is the pick: it's light, it vents well, and it adds a BOA fit dial. For bike park laps with a classic downhill feel, the Fox Rampage Comp Infinite is the value pick. For the lowest price into a downhill-certified helmet, the Leatt Gravity 2.0 is hard to beat. All three list ASTM F1952 downhill certification on their Perf-Moto product pages.

Perf-Moto's current sale pricing is the other story. At the time of writing, the Proframe RS FA22 is listed around $119 (list $359.95), the Rampage Comp Infinite around $126 (list $284.95), and the Leatt Gravity 2.0 from about $81 (list $169.99 to $179.00). That puts a premium enduro helmet in the same price range as the budget options.

This guide compares the three on the things that actually separate full-face helmets: certifications, rotational protection, ventilation, visor and goggle fit, fit systems, and weight. It also covers youth sizing, because a kid's helmet needs the same certification in a smaller shell.

Which Full-Face MTB Helmet Should You Buy?

• Long days with climbs and descents: Fox Proframe RS
• Mostly lift or shuttle laps, with a bold look: Fox Rampage Comp Infinite
• Lowest cost for a DH-certified helmet: Leatt Gravity 2.0
• Neck brace rider: Leatt Gravity 2.0, which lists neck brace compatibility
• Hot, dusty trails: Proframe RS for airflow
• Kids and teens: a youth full-face with ASTM F1952 certification, sized by head measurement (see the youth section)

What "DH Certified" Means: ASTM F1952 and Other Standards

Not every full-face helmet is tested the same way. ASTM F1952 is the downhill mountain bike standard, and it's the one to look for on a full-face MTB helmet. It's tested at higher impact levels than a standard bike helmet and includes a chin bar test, which is the part of a full-face that a normal bike helmet doesn't have. The other standards on these listings are baseline requirements for bicycle helmets in different regions.

Standard	What it is
ASTM F1952	Downhill mountain bike helmets
ASTM F2032	BMX bicycle helmets
CPSC 1203	US standard for bicycle helmets
EN 1078	European standard for bicycle helmets
AS/NZS 2063	Australia and New Zealand standard for bicycle helmets

Here's what each Perf-Moto listing says:

Helmet	Standards listed
Fox Proframe RS FA22	ASTM F1952 (DH), ASTM F2032, EN 1078:2012 + A1:2012, AS/NZ 2063-2020, CPSC 1203
Fox Rampage Comp Infinite	ASTM 1952-15, EN 1078, AS/NZS 2063, CPSC
Leatt 2.0 V24 Gravity	ASTM F1952-10, EN1078, AS/NZS 2063:2008, CPSC1203

Notice the different ASTM F1952 dates (-10 and -15). Both are listed as DH certified, but check the exact standard on the helmet you buy, especially for bike park rules.

MIPS vs Leatt 360 Turbine: Rotational Protection Explained

Most crashes involve a twisting force on the head, not just a straight hit. Both brands add a layer to help manage it:

• Mips Integra Split (Proframe RS): Perf-Moto's listing describes dual-density foam, one for high-speed and one for low-speed impacts, with a low-friction layer between them. The layer is designed to reduce rotational forces in a crash.
• MIPS (Rampage Comp Infinite): a low-friction system that helps reduce rotational forces transmitted to the brain.
• 360 Turbine Technology (Leatt 2.0): moving discs lined inside the helmet, built from an energy-absorbing material. Leatt claims reductions of up to 30% in peak brain acceleration and up to 40% in rotational acceleration.

These are manufacturer claims, and no helmet can prevent a concussion. Pick the system by fit and comfort first, because a helmet that doesn't fit well can't protect well.

Fox Proframe RS: Best Lightweight Full-Face for Enduro

The Fox Proframe RS FA22 is the helmet to look at if you pedal as much as you descend. Fox built it to keep the Proframe's light, open feel and add better rotational protection, a micro-adjustable fit, and more.

From Perf-Moto's listing:

• MIPS Integra Split with dual-density foam
• BOA fit dial with 52 micro-adjustments, plus a four-point back cradle
• Fidlock magnetic closure that works with gloves on
• 3-position adjustable visor with a lock-down screw, compatible with goggles
• Removable under-visor GoPro mount included
• Ionic+ anti-microbial liner and two cheek pad sets (thin installed, thick included)
• DH certified, ASTM F1952

OutdoorGearLab's review weighed the Proframe RS at 31.6 ounces, found it comfortable on chattery descents, and praised the airflow. It gives up a little weight to some enduro-focused rivals, but its ventilation is a standout.

It's $118.80 to $118.89 on sale (list $359.95) in Black, sizes S, M, and L.

Choose it if: you ride trails, enduro, and bike park days in one helmet, and you want a dialed fit.

Fox Rampage Comp Infinite: Best for Bike Park and Downhill

The Fox Rampage Comp Infinite is the more traditional downhill helmet in this group. Fox designed it to echo its race-winning RPC helmet, and the aggressive shape shows it.

From Perf-Moto's listing:

• Lightweight fiberglass shell
• MIPS impact protection
• Goggle-compatible adjustable visor
• Removable, washable, moisture-wicking liner
• Double D-ring closure
• ASTM 1952-15, EN 1078, AS/NZS 2063, and CPSC listed

The Rampage Comp Infinite is $125.82 on sale (list $284.95) in Bright Red and Navy Blue, with sizes listed from S to XXL. That size range is a plus for riders who don't fit smaller shells. Check which sizes are in stock before you plan around it.

Choose it if: you spend most of your time on lifts and shuttles and want a classic downhill helmet with a goggle-friendly visor.

Leatt Gravity 2.0: Best Budget DH-Certified Full-Face

The Leatt 2.0 V24 Gravity keeps the focus on protection and value. It has a downhill-certified polymer shell and Leatt's 360 Turbine Technology.

From Perf-Moto's listing:

• Stainless steel mesh vents that help block stones, dirt, and weather
• Breakaway visor, designed for additional rotational impact force reduction
• Premium washable liner for hot and cool conditions
• Double D-ring chin strap
• Optimal neck brace compatibility
• ASTM F1952-10, EN1078, AS/NZS 2063:2008, CPSC1203

Leatt lists the weight at about 960 g (plus or minus 50). OutdoorGearLab's review found the helmet plush and protective for the price, and noticed less ventilation on the trail, so it fits shuttle and bike park riding better than long pedaling days.

It's $80.99 to $118.99 on sale (list $169.99 to $179.00) in Fuel, White/Black, White/Red, and Timber, sizes XS to XXL.

Choose it if: you want a downhill-certified helmet at the lowest price, or you wear a neck brace.

Stepping Up to Carbon

If you want carbon, Leatt's Gravity 6.0 Carbon is the one to look at. Perf-Moto's listing for it recently became unavailable, so contact Perf-Moto to ask about restocks.

Fox Proframe vs Leatt Gravity: Which Is Better?

They're built for different jobs, so the better one is the one that matches your riding.

	Fox Proframe RS	Leatt Gravity 2.0
Best for	Enduro, trail, bike park	Bike park, shuttle, budget DH
Fit	BOA dial, extra cheek pads	Standard sizing, XS to XXL
Airflow	Standout	Mesh-covered vents, less airflow
Visor	3-position, goggle compatible	Breakaway
Closure	Fidlock magnetic	Double D-ring
Neck brace	Not listed	Listed
Perf-Moto sale price	$118.80 to $118.89	$80.99 to $118.99

Right now they overlap on price, which makes the Proframe RS the better value if you'll climb. Choose the Leatt if a neck brace or sizing range matters more.

Best Youth Full-Face MTB Helmets: What to Look For

A youth full-face helmet should have the same ASTM F1952 certification as an adult one, in a shell sized for a smaller head. Look for:

1. ASTM F1952 on the label or product page. If it isn't listed, it isn't a DH-rated helmet.
2. Rotational protection. MIPS or a comparable system.
3. A goggle-compatible visor that adjusts, so it works in dust.
4. A closure a kid can work. Double D-rings are simple and secure. Magnetic buckles are easy with gloves.
5. The right size, not room to grow. A helmet that's too big won't protect well.

Youth Helmet Sizing

Measure around the head, one finger-width above the eyebrows and over the widest part of the back. Then compare to the size chart on the product page, because ranges vary by model. As a guide, Fox's youth full-face sizes run from about 47 to 52 cm, and Leatt's junior sizes cover 51 to 54 cm (XXS at 51 to 52 cm and XS at 53 to 54 cm).

Brand	Typical youth range
Fox youth full-face	About 47 to 52 cm
Leatt Gravity 1.0 Junior	51 to 54 cm

Perf-Moto has carried youth full-face helmets from both brands, including Leatt Gravity 1.0 Junior and Fox Proframe youth models. Stock changes quickly, so contact Perf-Moto for current sizes before you order.

Parent Fit Check

• The helmet should sit snug with cheek pads touching the face and shouldn't roll forward or back.
• Have them shake and nod. The helmet should move with the head.
• Test it with their goggles on.
• Replace a helmet after any hard impact, and never use a secondhand helmet with an unknown crash history.

Goggles, Visors, and Ventilation

Full-face helmets block airflow, so ventilation and goggle fit matter more than they do on a half-shell.

• Proframe RS: the 3-position visor with a lock-down screw is built for goggles, and ventilation is its strong point.
• Rampage Comp Infinite: the adjustable visor is listed as goggle-compatible.
• Leatt 2.0: stainless steel mesh vents protect from debris, and the breakaway visor is designed to reduce rotational force in a crash.

Bring your goggles or glasses to a fit test if you can, because the gap between the visor and the helmet changes by model. Shop Perf-Moto's eyewear for goggles.

How to Size a Full-Face MTB Helmet

1. Measure your head with a soft tape, one finger-width above the eyebrows.
2. Match the size chart on the product page. Leatt's published sizes run in 2 cm steps (for example, S at 55 to 56 cm, M at 57 to 58 cm, L at 59 to 60 cm, and XL at 61 to 62 cm).
3. Check cheek contact. The cheek pads should touch your cheeks. Pads that float mean the helmet is too big.
4. Use the fit tools. The Proframe RS has a BOA dial and two cheek pad sets, so try both pad sets.
5. Check the strap. The closure should sit flat under the chin.

Complete Your Kit

A helmet is one layer. Round it out with neck braces, knee protectors, elbow and shoulder guards, back protectors, armored shirts, and gloves.

Helmet Care and Replacement

• Replace after a crash. Foam compresses on impact, and damage isn't always visible.
• Skip aerosol sprays. Perf-Moto's Proframe RS listing warns that bug repellent and sunscreen sprays can cause the helmet's finish to peel.
• Wash the liner. Removable liners can be washed. Let them air dry.
• Store it cool. Keep it out of hot cars and direct sun.

Frequently Asked Questions

What is the best full-face mountain bike helmet for 2026?

The Fox Proframe RS is the best for riders who climb and descend, thanks to its airflow, BOA fit dial, and DH certification. The Fox Rampage Comp Infinite is the best for lift-served riding, and the Leatt Gravity 2.0 is the best budget DH-certified option.

Fox Proframe vs Leatt: Which should I buy?

Choose the Proframe RS if you pedal a lot and want airflow and a dialed fit. Choose the Leatt Gravity 2.0 if you want the lowest price, a neck brace-compatible helmet, or a wider size range.

What is the best youth full-face MTB helmet?

The best one is ASTM F1952 certified, has rotational protection, and fits snugly by head measurement. Check the size chart for your child's head circumference, and contact Perf-Moto for current youth stock.

Do I need an ASTM F1952 helmet?

If you ride lifts, bike parks, or downhill, yes. It's the downhill standard, and many bike parks and enduro races require a full-face helmet. A standard bike helmet won't carry it, and convertible helmets vary, so check the label.

Can I wear goggles with a full-face MTB helmet?

Yes. The Proframe RS and Rampage Comp Infinite list goggle-compatible visors. Test your goggles with the helmet before you buy.

How long does a full-face helmet last?

Replace it after any hard impact. Beyond that, replace it when the foam, strap, or liner shows wear, or when the manufacturer recommends.

Is a MIPS helmet worth it?

MIPS adds a layer designed to reduce rotational forces in a crash. It's a useful feature, but the best helmet is one that fits well and carries the right certification.
