Description

A visor helmet solves a problem most skiers have quietly accepted: goggles that fog, pinch, and leave a cold gap across your forehead. The Driver Prime carries a SIGMA lens on a magnetic mount instead, so it lifts out of the way on the lift and drops back down in one motion, and it is designed to be worn over prescription glasses rather than fought with.

Underneath it is the most protective helmet Salomon build. MIPS handles the twisting forces of an angled crash, EPS4D absorbs the straight-on ones, and Smart Safety 360 wraps EPP around the rest of your head rather than just the top. A BOA dial and a Fidlock magnetic buckle mean you can put it on and take it off with gloves, and the liner is 100% merino wool, which comes out and washes.

Features
  • Magnetic SIGMA visor. A wide, low-distortion lens on a magnetic mount. Strong enough to stay put, easy enough to swap with gloves on, and built to sit over glasses.
  • MIPS with EPS4D. MIPS reduces the twisting force of an angled impact; EPS4D is Salomon's own foam for straight-on absorption. Used together rather than as alternatives.
  • Smart Safety 360. EPS4D on top with EPP wrapped all the way round, so the sides and back of your head get real protection rather than a thin shell.
  • BOA® Fit System and Fidlock. A low-profile BOA dial micro-adjusts the fit, and the Fidlock buckle closes magnetically with one hand — both work in gloves.
  • Merino wool liner. 100% merino, which breathes and resists odor far better than synthetic padding. It lifts out and washes.
Size & Fit
  • Salomon build this helmet on an oval fit, which suits a head longer front to back than it is wide
  • It should sit level, about two fingers above your eyebrows, snug with no pressure points
  • With the strap undone it should move with your head rather than sliding on it
  • Use the BOA dial for the last of the adjustment, not to rescue a size that is too big
  • Do not wear a beanie underneath — the merino liner is there to do that job
  • We stock Medium and Large, in White and Black

Materials
  • Upper shell: injected ABS.
  • Lower shell: in-mold polycarbonate.
  • Impact liner: EPS4D expanded polystyrene with all-round EPP.
  • Comfort liner: 100% merino wool, removable and washable.
  • Ear pads: 3D construction on a MaxFit V-shaped frame.
  • Care: wipe the shell with a damp cloth and mild soap only, and clean the lens with the supplied bag rather than anything abrasive.

Performance

How it ranks across conditions.

Calibrated against comparable products we stock, so you can compare like for like.

Warmth

Vented
Balanced
Warm

Salomon rate the ventilation level medium and line it with merino wool. With the vents closed it is a warm helmet; open, it breathes.

Ventilation

Fixed
Adjustable

Active ventilation — you can open and close the vents to change the airflow, which the cheaper Pioneer 3 Access cannot.

Impact system

EPS
MIPS or equivalent
Advanced rotational

This is MIPS, which is the rotational layer. Salomon stack EPS4D and Smart Safety 360 around it, so the whole package protects more than MIPS alone — but the rotational element itself is standard MIPS.

Weight

Light
Moderate
Sturdy

Salomon publish 1 lb 11 oz, about 765 g. That is heavy for a ski helmet, but this is a visor helmet with a lens attached, so it is not a like-for-like comparison with a bare shell.

Best for

Is this right for you?

Skiing in glasses

Salomon list this helmet as prescription-glasses compatible, and a visor sits far enough off your face to make that workable in a way most goggles do not.

Not for: A visor is more exposed than a goggle in a crash or a tree branch, and a scratched lens is a replacement rather than a cheap fix. Prefer goggles? Browse ours

Changing light

Two lenses in the box: a Category 3 for sun and a Category 2 for cloud. The magnetic mount means swapping them takes seconds at the top of a lift.

Not for: Neither lens is a low-light or night category, so a genuinely dark storm day will still be dim. Browse all ski helmets

Maximum protection

MIPS, EPS4D and Smart Safety 360 together. If protection is the reason you are buying, this is Salomon's most complete answer.

Not for: It is heavier and costlier than a simple in-mold helmet, and it is certified to the European ski standard only. Everything else for the hill

Questions, answered

Before you buy.

Pulled from chats, emails and store visits. The things people actually ask us before they buy. Don't see yours?

Ask a question
Do I need MIPS?

MIPS is a low-friction layer that lets the shell rotate a few millimeters against your head, reducing the twisting forces in an angled crash. Most ski falls are angled rather than straight down, so it is a real benefit rather than marketing. This helmet has it, paired with Salomon's EPS4D foam and all-round EPP.

How should a ski helmet fit?

Snug all the way round with no pressure points, sitting level so the rim is about two fingers above your eyebrows. Shake your head with the strap undone: the helmet should move with you, not slide. Then tighten the BOA dial to take up the last of the slack. If it rocks forward and back, it is too big.

Do I still need goggles with it?

No — the visor replaces them. A SIGMA lens comes fitted and a second lens in a different category is in the box, both on a magnetic mount. If you would rather use your own goggles some days you can lift the visor out of the way, but the helmet is designed around the visor.

When do I have to replace it?

After any real impact, even if it looks perfect — the foam crushes to absorb the hit and does not spring back. Beyond that, manufacturers advise replacement every three to five years regardless of use, because the foam and the shell degrade with time, sun and heat. The lens can be replaced on its own.

Can I wear a beanie under it?

No. A hat lifts the helmet off your head and defeats the fit system, so it can move or come off in a crash. The merino liner is there to do the warmth job instead. If you are still cold, use a thin balaclava designed for the purpose and size the helmet with it on.
