Bern fans rejoice.

It was a long time coming, but last year Bern finally released their first cycling-specific helmet: the Allston. The designers worked with the world's best cyclo-cross racers and bicycle messengers to create a helmet that performs as well as it looks, from rugged cross courses to urban environments, and haven't seen the need to mess with what works.

Sixteen strategically-placed vents result in fifty percent more airflow than in other Bern models, making it ideal for hot days and long rides. Zipmold technology uses a liquid injection method that fuses lightweight high-impact foam and a tough PVC shell to protect your noggin without weighing you down, and Sink Fit features a low-profile configuration so the helmet fits around your head, not on top. An integrated visor can be worn flipped up to suit your style or down to shade your eyes.

Snug fit

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: L/XL

A bit snug at first (my hat size is 7 3/8), but the fit got better with time. (My previous helmet was 5 years old & sat higher & sloppier on my head.) Love the look, rounded design, & the added back of the head protection. Visor is a bit low, but that's inherent in the design. If the visor is a deal-breaker, the Bern Morrison has a more MTB visor & look.

Love the fit... but, meh on the visor.

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size
  • Size Bought: S/M

I bought both the S/M and L/XL to compare fit size. I've worn Giro Atmos helmets for the last 4-5 years and wear a true medium in them so I was borderline on the Bern.

Turns out the S/M fit was perfection with almost no adjustment out of the box.

This helmet was purchased for use mountain biking and bikepacking but I could totally see its value for any active sport where wider rear-impact protection would be needed. I'd rock this helmet for skating, snowboarding, horseback, et al. It's not intrusive and cool enough, even when moving slower.

My only redesign would be to narrow the visor just a bit. Having the flip option is sweet but when it's down, you cannot see anything far ahead without serious craning of the neck or sitting straight up and bending your neck up to see under. It is WIDE... which is great for sun protection but not so much for field of view. You can only see what's approaching directly in front of the tire with little time to react.

for SKIING also!!!

  • Familiarity: I've put it through the wringer

Bought this thing as a ski helmet - and it rocks. Super light weight for ski touring - you wont even notice its there until it keeps your brains in your skull.

What I did to mod this thing for skiing was to rip out all of the inside linings and cut the inside fitting for the visor so that i could keep it on the helmet but have room for a BEANIE (see Doyonator beanie from Discrete) -

It fits super well this way and looks GREAT WITH GOGGLES!

Now i have zero excuse to ski without a helmet!


I'd like to exchange it to Black color S/M size.

so do I need to send it as the way return ?

Hey Inwoo K,

Allston for one and one for Allston.

  • Familiarity: I've used it several times

This helmet is one of the best helmets I have ever owned! Since the day I pulled it out of the box I have loved everything about it and I get excited to ride my bike just so I can wear it!

Bern really nailed it with this helmet. Seriously. Some people say that the downside to Bern helmets is that they are not very adjustable, which is true, the adjuster on the back of the helmet does not have a wide range, but that is actually something that I really like about this helmet. I did have to measure my head before for fear of getting the wrong size, but I got the right size and it sure is comfortable! With the low amount of adjustment, the helmet actually feels like it is made for my head and isn't crazy big or have a lot of room to move around. The straps lie flat against your head which is something I really like, but be warned! The straps around your ears are not adjustable! Mine fits me great, so no issues for me, but if it doesn't fit you well, that could be a problem.

Build Quality
The Allston helmet has a great build quality and everything seems tight and how it should be. The straps are solid, the seams are great, and the visor stays in place even if you have it up or down. Even with all this great build quality, Bern still made it possible to easily remove the liner with the attached visor, and you can even remove the straps if you want to wash them separately. Not something really necessary, but it is nice to know that I have the option.

Flip Visor
I wasn't sure if I would like the look of the flip visor when I first ordered it, but I have used it so much! When the sun is in your face, you just flip down the visor and bam! You can see! It comes down lower than a standard helmet visor and has the same feel as a cycling cap, so Bern really figured it out on this helmet.

I recently wore this helmet for an 80 mile trip on a mix of road and mountain trails and it does great at everything. At the end of the day it was great to be able to take out the liner to let it dry a little quicker and even after a long day of riding, my head didn't hurt at all and I didn't even notice I had the helmet on while I was still setting up my tent.

Great helmet that has a great look! The Bern Allston is on point!


  • Familiarity: I've used it several times

This helmet is a handy multipurpose lid I keep in our car, ready for MTB or trips to the skate park.

My son uses it on his urban bike, mountain bike and to skate in.

Very well ventilated, the rim is removable and washable.

The only issue I found was the sizing ran large and is hard to dial in. Other than that the Allston is a great brain bucket.


Is the liner totally removable for summer riding?

Hey Barrett,

Yes it is. It snaps in - you can actually get a winter liner and wear this all year long. The summer liner is just a thin meshy material - the main feature is the brim, but that pulls out with the rest of the liner.

Ski mountaineers rejoice

  • Familiarity: I've put it through the wringer

Bern's premise really strikes a cord with me--when you do lots of things that require helmets of a similar style and strength need, what's the point of owning more of them? Though the Allston is billed as the first "bike focused" helmet from Bern, the inner caution notes that it is "intended for use in biking, skating, and other non-motorized recreational snow sports (such as skiing, snowboarding, and other alpine sports)".

This crossover is especially helpful in solving the problem of the ski mountaineering helmet. It has to be light and breathable, but also able to deal with the lateral impacts that can result from a ski crash. This counts a lot of the climbing focused helmets out, as they're designed towards vertical rock fall, not lateral head impact. So in the Allston, I've found a great option that works great while running bike errands around town or while doing committed ski mountaineering.

I find the locked down ear straps to be really nice, as you don't have to hassle with them. The boa style back cinch allows for a beanie or helmet liner underneath, or just going bare head. I'd recommend some kind of liner or hood for cold use, as it certainly vents well enough to be cold with nothing else there.

Perhaps not as light as some of the mountaineering helmets out there, but I like the peace of mind in knowing that it's got better chops for a ski wreck.

Breathable Bern!

I recently received this updated version of the Allston, and am an even bigger fan than I was of the first edition Allston.

The two main updates over the previous version are; revised rear retention system and a fixed position under the ear chin strap.

The previous double Velcro retention system, that I do not feel helped securely snug the rear of the helmet to your head is now a 'BOA' style dial that is fixed to the inner liner and helps snug in the rear of the helmet quite nicely.

The previously adjustable straps under the ear, that I feel are a constant battle to find the right position as well as lay flat on the face; have been replaced with a non adjustable, sewn strap that is very comfortable next to skin and is a vast important in my eyes.

The stand out feature of this helmet above all other previous Bern models would certainly be it's ventilation; with 16 large vents, I have no issues wearing this with or without a cycling cap on warmer days. This is my go-to helmet for commuting around town, running to the store/bar, and any other cycling adventure where I would prefer a more durable helmet over a super lightweight one.
