Chicks dig teeth. Wear a helmet.

The POC Cortex Flow helmet is a bit different than its Cortex DH big brother. First of all, it's a single-shell helmet. The exterior is made of fiberglass, and the single layer design necessitates a thicker shell. So it's a more durable shell than the carbon fiber on the Cortex DH, but it's also a heavier shell.

While it takes external design cues from the Cortex DH, the single shell means the vents channel air directly into the helmet, through holes in the shell that are aligned with a like pattern in the EPP liner. In reality, it ventilates better than the DH version because of this direct flow path for fresh air. The chinguard is positioned just right to provide coverage but ensure you can still breathe easily on hot days as you sprint from one berm to the next.

The Cortex Flow helmet meets all the European and US safety standards. As mentioned, it vents better than its DH big brother. But the DH is a much more robust helmet with its double layer construction and MIPS technology. If you're prone to bailing but live for high-speed excitement, do yourself a favor and go for the DH version of the Cortex Helmet.

Replacement brain bucket

  • Familiarity: I've used it once or twice and have initial impressions

Great fit using the additional cheek pads. Great price. Looks awesome too!


  • Familiarity: I've used it several times

Light enough, comfortable enough, and doesn't look or feel like you have the death star on your head. So far pretty impressed with performance etc, and hope I never have to test out it's protective qualities.

Saved My Noggin

  • Familiarity: I've put it through the wringer

I wear a large in pretty much every helmet. The large fit me a little big, but when I put in the larger cheek pads that were included it fit great. A little on the heavy side, but not so much that it was uncomfortable. I used it primarily for DH up at The Canyons and Deer Valley. Really glad I had the full face protection when I crashed this summer. Went down at roughly 25-30 mph and slammed race first. Hit my forehead on a rock and slammed what would have been my jaw into the dirt for a good 30'. Walked away with a headache but nothing else. I'll be replacing it next season with a new one.

Heavy, but Worth the Extra Protection

  • Familiarity: I've put it through the wringer

I picked this helmet up last season and have used it every time I'm riding lifts or doing DH. It's heavier than other brands I've used but I appreciate the extra protection that this helmet offers. One thing that could be improved is the ventilation. I found this helmet to run a bit small.

Great Brain Bucket

    I wanted to make sure I had a snug fitting helmet and ordered a L originally based off the sizing guide because my head circumference was right in the middle of the range for a Large. I sent it back and got a medium accounting for the padding packing out over time. Medium is much snugger, responsive to where I'm glancing or looking around, and is a much better fit for me. I have a huge beard as well, and it slides in easily.

    I wear this helmet for fast trails on Mt. Elden in Flagstaff and at Big Bear and it is an amazing helmet for this style of riding. Comfort and breathability are optimal and I'd repurchase or recommend to friends.

    Unanswered Question

    great helmet but I lost one of the screws that secure the visor to the helemet. Can backcountry order me an extra or two in case I loose another?

    Size/Shape issues

    • Familiarity: I've put it through the wringer

    I'm a 7 and 5/8 hat size, usually a 61 or 62 cm helmet. I've had Giro helmets consistently over the years but wanted a full face for specific skiing last season. I'm used to full face motorcycle helmets - both dirt bike and road, so I thought the fir of this L/XL would suit me. It has been agony, and have I've persevered for around 20 ski days with it. Pressure points are in all the wrong places for me. It's a shame because build quality is excellent. Make sure you try this on before you buy.

    Big Ass Head

    • Familiarity: I've put it through the wringer

    I have a big ass head. The L/XL fit me good. I fell real hard on my head in a rock garden in Trestle Bike Park during a race. A few scratches and no concussion when I probably should have gotten one. Too bad I broke my arm cause if not I would have probably finished. I will give it a 5 cause I still remember how to do math.

    Breathes really well in the heat. Awesome with POC goggles.

    Sizing runs Large

    • Familiarity: I returned this product before using it

    So I usually wear a medium in many POC products most recently the Receptor Backcountry MIPS. I got this one in a medium on advice from a few sources and find they were all way off. This one does not run smaller like the Backcountry. This one is at least a full size larger than what will fit me. If your like me and in between the sizing chart POC has posted, then size down, you won't regret it. Aside from that hard to give an honest review until I have actually used the product on the hill... When I get the replacement I will fill y'all in!

    So I own POCs receptor backcountry and find the m/L to fit awesome though I have a very small head. Any insight as to sizing on this model. Should I go with a small or go with the medium having a small head? Any insight would be much appreciated.

    If you wear a M/L in the Receptor Backcountry the M/L of the Cortex Flow should be almost the exact same sizing.

    Turned out to be Ginormous compared to my Backcoutntry. Definitely need to size down...


    • Familiarity: I've used it once or twice and have initial impressions

    I'm really excited about picking up this helmet. Yeah its big, but I'm more concerned about surviving. The interior is plenty plush, and having options for the cheek guards ensured a proper fit.

    Only recommendation is that you look at what color you're buying. Ordered Bohrium Red and in the picture it looks like a matte finish, but it is not. My fault, I could have just looked at the video and seen the reflection.

    Can I remove the visor?

    Can I remove the visor?

    Best Answer

    yes, the visor on the Cortex Flow helmet is removable.

    Very light

    • Familiarity: I've used it once or twice and have initial impressions

    Very light, good fit, doesn't move on my head. Poc makes very great protection equipment and this is no different! love the blue!

    Best helmet yet

    • Familiarity: I've used it several times

    Been downhilling for 20 years. Started with the Foes Weasel. Have had at least 5 helmets over the years. This is the best so far. Great fit for me. Smallish head size the s/m fit perfectly. Light and comfortable.

    Super stylish but not super plush

      I am a fan of the simple color patterns and design characteristics, I used this helmet for two seasons until I took a massive hit to the head and had to retire it. I definitely recommend the helment and feel that it is one of the best looking helmets on the market. It breathes well and integrates with goggles nicely.

      My only complaint is that it is not as soft and plush inside as other helmets in the same price range, which is surprising because I think the other POC helmets (the Trabac and the flow) are very plush. It is also pretty light weight compared to some of the other helmets I have used, the cheek pads do take a while to break in and always felt like they put unnecessary pressure on my face for the first 10 or so uses. But all in all I would say it is a great but not perfect helmet.

      Couldn't ask for better!

        This helmet is so comfortable. Its great for downhill riding and even rides that require some pedaling. Its super lightweight and is so easy to breath in. The face guard does come out a little far, but it isn't that noticeable. The helmet doesn't overheat much, but then again, I've only rode in winter weather. I love it. So glad i bought it!

        The future

          While this helmet does make you look a little like you just got off a space ship, it's low weight and comfort make up for the funky look. Best of all, this helmet vents better then the D2, and doesn't feel quite as claustrophobic. As long as you don't require flames on the side of your helmet, then this is a solid choice.

          Nice upgrade

            I moved up from Giro to 661 and now a POC. This is my favorite so far. Never was a fan of the TLD stuff and the POC line-up of stuff is top notch. This helmet is nothing less than awesome. Plenty of viewing space to see the trees coming at you, and the vents do there best to keep your melon cool. I've got my helmet paired up with the POC iris google and its a match made in heaven. If you are looking for a lightweight, no carbon lid go try one of these one, the are super comfy.

            Nice upgrade

            Lightweight & comfy

              Great helmet... Light and decently breathable (it's still a full face, you're gonna get sweaty), with a great field of vision. Comes with 2 sets of ear pads to help you dial in the right fit.
