Zerna™ Beanie is rated 4.3 out of 5 by 8.
Rated 1 out of 5 by from I wanted to like it ! I bought this hat mainly to match my shark/state orange Phantom jacket. I got a "regular" to begin with , as I'm just an average size guy (6' 200lbs.) It wouldn't even fit on my head! I returned it and bought a large. The FIRST TIME I put it on, the orange band split in the back. The second problem I had was all I could hear was wind through the vent holes over the ears on the side. It was really annoying. The third problem was it wasn't very warm (IMO) I returned it to the store today and got the Perignon lite and I love it. I definitely do not recommend this hat.

Rated 5 out of 5 by from Awesome hat! This hat is great! I had it on under my helmet all day ice climbing and I didn't even know I had it on. The fit is true and perfect, and the thin profile fits great under a helmet. I actually had this hat on and the hood of a mid layer under my helmet and it was very comfortable. The temps were in the single digits to low teens all day and I was very warm.

Rated 5 out of 5 by from Great hat. Windproof and thin enough to fit under my climbing helmet with full ear coverage.

Rated 5 out of 5 by from Good for aerobic activity This beanie cap is lightweight but suprisingly warm. I use this cap primarily for running and other active outdoor activities. I wear a 7.25 (57.7cm) fitted baseball cap, and this beanie fits just right. It completely covers my ears and extends below my brow. This beanie is very stretchy and is fairly warm for a non-insulating style cap.

Rated 4 out of 5 by from Cycling beanie Being, genetically speaking, one of those unfortunate individuals blessed with a large cranium it is hard for me to find hats and helmets that fit. It is even harder to find one that fits and doesn't make my head look like a lollypop. I finally found a helmet that I wasn't embarassed to wear and then it got cold. Short story long, I bought the Zerna and am very happy with it. The volume I feel is a little big but even without adjusting it I can fit it under my helmet and it keeps my monstrous ears completely covered and warm whilst still being very minimalistic. Must have for anyone wearing helmets in the cold.

Rated 5 out of 5 by from Warm This hat is surprisingly warm for how thin it is. It fits great under my climbing helmet.

Rated 4 out of 5 by from Great Helmet beannie So I really like this beanie! I wasn't sure it was going to work out because it is so thin but I have found this quality to be why I like it so much. I have snowshoed, rafted, ran in the rain, and casual town wearing in this hat. Works great with a helmet!! Blocks the wind amazingly for being so thin and breathable. My only complaint is the fit. Does not fit my head shape well at all. I have a lot of extra material I push to the back of my neck. This would be a deal breaker in most cases but this piece functions under helmets and in wind so well I would have to recommend this and if you have a perfect shaped head for the hat...that would be awesome.

Rated 5 out of 5 by from Best I have found As a shaved-head or skin-tight hair guy, I am qualified on hats. This thing is great under a helmet or alone in windy conditions. The best feature is the band around the ears that provides tension. Fit is snug and it covers the head well. My hat size is 7&3/8 and the regular is great.
