The quick verdict: The visor-brim original, now with MIPS and a fit dial, and it converts to a bike helmet when the snow melts. ~$170-180 list, typically ~$85-120 on sale
Overview
Before style-first snow helmets were a category, there was the Bern Watts. The 2.0 keeps the molded visor brim that made the silhouette famous and brings the internals up to date: a MIPS rotational liner, Bern’s Compass fit dial, and a hybrid DSI shell Bern says is about 20 percent lighter than the original.
Its defining feature is the dual life. Pop out the insulated winter liner and the Watts 2.0 is certified and comfortable for bike and skate duty, which makes the roughly $170 to 180 list price (often $85 to 120 on sale) look different when it replaces two helmets. The tradeoff is thermal: the design runs warm, great in January, less great during slushy April laps.
Where It Shines
- One helmet covers snowboarding, biking, and skating
- MIPS plus a proper fit dial in a style-first shape
- Visor brim cuts glare without goggle interference
- Durable shell built for daily-driver abuse
Tradeoffs to Know
- Runs warm; spring riders will want more venting
- Heavier than snow-only designs of similar coverage
- Visor look is polarizing on-hill
Who It’s For
Riders who bike or skate in the off-season and want one lid for everything, plus anyone who has always wanted the classic Watts look with modern protection. Dedicated snow-only riders may prefer the Anon Windham WaveCel’s snow-first design.
Key Specs by Size
Figures are approximate and drawn from Bern’s published specs and sizing (via bernhelmets.com) plus evo and REI listings. Bern makes the Watts 2.0 MIPS in three adult sizes, and the same shell sizing applies to the bike and snow versions.
| Size | Head circumference | Published weight |
|---|---|---|
| S | 52-55.5cm (20.5-21.9in) | ~350g bike setup; ~500g with winter liner |
| M | 55.5-59cm (21.9-23.2in) | ~350g bike setup; ~500g with winter liner |
| L | 59-62cm (23.2-24.4in) | ~350g bike setup; ~500g with winter liner |
Across all sizes: Bern’s DSI (Dual Shell Integration) construction pairs a Zipmold+ lower shell with an ABS top shell, which Bern says comes in about 20 percent lighter than the original Watts. Inside sits a MIPS rotational layer over a ribbed RibTech EPS liner, with the Compass Fit dial at the back and 11 fixed vents. The snow version ships with a removable winter knit liner whose ear cups have an openable pocket for drop-in Bluetooth speakers, plus a second set of warm-weather padding for bike season. Certifications: CPSC for bicycles (ages 5 and up), EN 1078 for bike and EN 1077 Class B for snow. Retailers list a one-year warranty. List price is about $170 to 180; with the current colorway cycling through outlets, sale pricing in autumn 2026 runs roughly $85 to 120 depending on size and color.
Sizing and Fit
Measure around the widest point of your head, about a finger’s width above the eyebrows, and match it to the chart above. If you land on a boundary (55.5cm or 59cm), take the smaller size: the Compass dial opens the fit a long way, but it can’t shrink a shell that is already loose, and a Watts that rocks on your head defeats the point of MIPS. Bern’s adult shells tend to run round rather than oval, so riders with a long, narrow head sometimes find pressure at the temples and front; if that describes you, try one on before committing.
The winter liner adds real bulk, which is why Bern’s own weight figure is closer to 500g while bike listings quote around 350g. That extra material is warm, and it also means the helmet fits noticeably tighter in snow mode than it will in July with the thin pads swapped in. Expect it to break in a little over the first few days as the knit compresses. For goggles, Bern designs the Watts around its own B-1 frames, but the hard brim leaves room for most medium-frame goggles worn under it; oversized cylindrical frames can bump the brim edge, and over-the-helmet strap wearers should check that the dial housing doesn’t push the strap up.
Who Should Skip It
Skip the Watts 2.0 if you ride mostly in spring or in a warm, wet coastal climate: 11 small fixed vents and a snug knit liner trap heat, and the Smith Scout MIPS gives you adjustable venting for less money. Skip it if you want the lightest snow-only lid you can get with a rotational liner, because the Anon Windham WaveCel is built for snow first and feels it. And skip it if the brim and skate silhouette aren’t your style; the Giro Ledge MIPS delivers the same MIPS protection in a plainer shape at a lower price.
Watts 2.0 MIPS vs. Giro Ledge MIPS vs. Sandbox Classic 2.0 Snow
All three are style-first, low-profile lids, but they solve different problems. The Giro Ledge MIPS is the value play at about $100: MIPS, a simple fit, no brim, and nothing you don’t need. The Sandbox Classic 2.0 Snow is the pure skate look at about $120, with a brim like the Watts but no MIPS and a stiffer, more minimal feel. The Watts 2.0 MIPS costs the most at list, roughly $170 to 180, and justifies it with the dual certification and swappable padding that let it serve as your bike helmet too; on sale it often lands near the other two. Pick the Ledge if you want MIPS for the least money and don’t care about a brim. Pick the Sandbox if the look is the point and you ride park more than you ride fast. Pick the Watts if you’ll actually wear one helmet for snow, bike and skate, or if you want the brim and MIPS in the same shell.
Frequently Asked Questions
Is the Bern Watts 2.0 MIPS good for beginners?
Yes. It carries full snow certification, MIPS, and a dial fit that is easy to get right, and the brim helps new riders who haven’t sorted out their goggle setup yet. The only beginner caveat is warmth on mild days.
What size Bern Watts 2.0 should I get?
Measure your head: S fits 52-55.5cm, M fits 55.5-59cm and L fits 59-62cm. On a boundary measurement, go smaller and let the Compass dial do the rest.
Can I use the Bern Watts 2.0 MIPS snow helmet for biking?
Yes. It is certified to CPSC and EN 1078 for bike as well as EN 1077 for snow, and the winter liner swaps out for the included warm-weather padding. Bern calls this its All Season setup.
Is the Bern Watts 2.0 MIPS discontinued?
Not as a model; Bern still lists it in six colors. Individual colorways turn over each season, which is why REI and evo show some versions as closeout or sold out at deep discounts.
