1 / 4Smith Accel MIPS Helmet
Pre-order · Ships September 2026
Description
The Smith Accel Mips is Smith’s do-it-all resort helmet, the model where the brand’s Koroyd-and-Mips protection meets the fit and vent hardware that cheaper lids leave off. It is built for skiers who spend the day lapping groomers, trees, and the odd storm cycle and want one helmet that covers all of it.
Protection comes from a pairing of systems. Zonal Koroyd places energy-absorbing tubes in the key impact zones, and the Mips layer addresses the twisting forces of an angled fall. Both sit inside a one-piece in-mold shell that keeps size M at 450g, and the whole thing is certified to ASTM F2040 and CE EN 1077:2007 Class B.
Comfort is where the Accel earns its keep. Turn the rear dial and the fit tightens 360 degrees around your head; slide the Regulator and airflow opens or closes as the weather changes. The liner treats odor and bacteria over long weekends, the shell pairs with Smith goggles, and it plays with Aleck audio for skiers who like music on the lift.
A helmet only does its job when it fits right. Stop by the shop and we will measure you, dial the fit snug and level, and check it against your goggle. Ordering online? Send us a tape-measure reading just above your ears and we will confirm your size first.

Smith Accel Mips Ski Helmet
Accel family · 26/27
Technology
In-Mold Construction
The outer shell is fused to the EPS foam liner in one lightweight piece, which keeps the Accel at 450g while staying durable for a full season of resort days.
Koroyd (Zonal)
Welded co-polymer tubes that crumple on impact to absorb energy while staying open for airflow, placed in the Accel’s key impact zones rather than across the full shell.
Mips
A low-friction layer inside the helmet that lets it move a few millimeters on an angled impact, designed to reduce the rotational forces caused by angled impacts to the head.
Regulator Climate Control
Single-slider Regulator venting you move with one hand to open or close airflow through the day, so you can dump heat on warm groomers and shut it down on cold chairlift rides.
Features
- ·Light 450g in-mold shell for all-day comfort
- ·Zonal Koroyd plus Mips for impact and rotational management
- ·360° micro-adjustable dial to fine-tune the fit on the go
- ·Regulator climate control opens and closes airflow one-handed
- ·Ionic+ lining with anti-odor and antimicrobial treatment
- ·Designed to integrate with Smith goggles for comfort and venting
- ·Aleck audio compatible
- ·Select colorways available without Mips at a lower price
- ·Includes a Smith helmet bag
The Smith Accel Mips is the entry lid in Smith’s tough, lightweight Koroyd line, and it puts real adjustability at a working price. An in-mold shell fuses the outer shell to the EPS liner in one piece and comes in at 450g in size M, while zonal Koroyd sits in the key impact zones to absorb energy and keep airflow moving. Mips manages the rotational forces of an angled impact, and certification is ASTM F2040 plus CE EN 1077:2007 Class B.
The Accel is where Smith adds the hardware the cheapest lids skip. A 360° micro-adjustable dial lets you fine-tune the fit with one hand, and a single Regulator vent slides open and closed so you can move air on a warm groomer and shut it down on a cold chair. The Ionic+ lining carries an anti-odor and antimicrobial treatment for long days, the shell is built to integrate with Smith goggles, and it takes an Aleck audio system if you ride with sound.
The Accel suits a skier who wants a dial fit and adjustable venting without paying for Smith’s top-tier shells. It runs single-slider Regulator venting, so if you want more adjustable airflow you would step up in Smith’s Koroyd line, such as the Level with its added vents. Zonal Koroyd covers the key zones rather than the full shell, and select colorways ship without Mips at a lower price if you want that version.
Safety — read this
No helmet prevents all injury. The Accel meets ASTM F2040 and EN 1077:2007 Class B; Koroyd and Mips are impact-management systems, not guarantees, and Mips is a rotational-impact feature rather than a certification. Replace any helmet after a significant impact even if it looks undamaged, and check that the dial fit sits snug and level before you ride.
Strengths
- +Light 450g in-mold shell, easy to wear all day
- +Zonal Koroyd and Mips manage impact and rotation
- +360° dial fine-tunes the fit one-handed
- +Regulator vent opens and closes airflow one-handed
- +Ionic+ lining resists odor over long days
Best For
All-mountain and resort skiers who want a dial fit and adjustable Koroyd-and-Mips venting at an entry price.
Limitations
- −Single-slider Regulator venting — less airflow control than pricier lids
- −Zonal Koroyd covers key zones, not the full shell
- −450g is midweight, not an ultralight lid
Not For
Skiers who want more adjustable venting than one slider should step up in Smith’s Koroyd line, such as the Level with its added vents; anyone who wants to ride without Mips has to choose one of the select non-Mips colorways.

Common Questions
- How much does the Smith Accel weigh?
- About 450g in size M. Its in-mold construction fuses the shell to the EPS liner in one piece, which keeps it light for a lid with a dial and adjustable venting.
- Does the Smith Accel have a dial fit?
- Yes. The Accel uses a 360° micro-adjustable dial, so you can fine-tune the fit with one hand while you wear it.
- Does the Accel have Koroyd and Mips?
- Yes — zonal Koroyd in the key impact zones plus Mips, which reduces rotational forces caused by angled impacts. Select colorways come without Mips at a lower price.
- Can I adjust the vents on the Accel?
- Yes. The Accel uses Regulator climate control, single-slider venting you move with one hand to open airflow on warm runs and shut it down when it is cold.
- Is the Accel certified?
- It meets ASTM F2040 and CE EN 1077:2007 Class B. Those are the safety certifications; Koroyd and Mips are add-on impact-management systems, not certifications themselves.
