j.a3006219wrote a review of Bern Allston Helmet with Flip Visor on January 21, 2016
Familiarity: I've used it once or twice and have initial impressions
Fit: True to size
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.
