Face facts.

As much as we'd like to, we all can't be a part of the Atherton family. While their smooth, speed-hungry gene pool will always amaze and forever elude us, we can put our own mediocre genes to work on rough and rowdy DH trails knowing our grey matter's protected with Fox Racing's ultralight, MIPS-equipped Proframe Helmet. Don't be surprised if it inspires you to send a little harder, whether in your own backyard or deep in the Welsh countryside.

As the lightest DH lid ever made by Fox, the Proframe comes with the same full-face, fixed visor protection of a classic DH bucket—albeit in a more streamlined design that won't leave you with your head hanging after an all-day ride. Its low weight means that even if you ride more towards the enduro end of the spectrum, you won't sacrifice time in a race for upgrading to DH-level protection. Fox also punches 24 Big Bore vents into the Proframe's shell, making sure you don't feel like you're trying to ride in an astronaut helmet when you're grinding it out on a long, rocky ridge climb before a serpentine descent.

  • Ride with full DH protection without the bulk
  • Dual-density Varizorb EPS broadly distributes impact
  • MIPS inner basket helps disperse rotational energy
  • Fixed visor and chin bar provide protection with airflow
  • 15 intake and 9 exhaust vents keep air moving continuously
  • Fidlock SNAP buckle made to be operated with gloves

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

This Helmet rocks! Super lightweight and comes with a lot of different sized pads to dial in the fit. I would recommend this to anyone looking for a lightweight full face that they wouldn't be upset about pedaling a couple miles in.

Want it to fit

    This helmet looks awesome, and I really wanted it to work for enduro racing -- but the lack of an adjustable system didn't work for me. The pads weren't thick enough to offer stable support in the helmet. Sadly had to return it and find another enduro lid.

    Don't be fooled THIS IS not a DH Helmet

    • Familiarity: I've put it through the wringer

    Just to be clear I'm a 30yr DH Veteran NOT a beginner. i ride +- 120 days a year, Make no mistake this is NOT a DH helmet I was involved in a low speed impact >18mph, The helmet failed catastrophically leaving me unconscious for roughly 2 1/2 hours, I woke up in the hospital.

    Really comfortable, but less adjustable

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

    I haven't gotten to wear it yet as I bought it just as winter was arriving, but the helmet feels extremely light and comfortable. I just wish it had a better way to adjust the fit, as I feel like the Medium is just barely too big in its standard position, but using the larger pads makes it feel too tight. I've never worn a DH helmet before though (unless you count a dirt bike helmet), so I just may be unfamiliar with their design.

    Best gear ever!!!

    Well vented & light helmet to substitute my trail helmet,it saved my face from my 1st wipeout...Thank God for Fox Proframe.And matches all my kit.

    Best gear ever!!!

    Great helmet, poor fit for giant heads

    • Familiarity: I returned this product before using it

    I really wanted to love it, but it lacked an adjustable fit system which left the MIPS liner digging into my giant cranium and causing massive irritation, even in the XL size. Tried all the pad adjustments and some more creative options, but it just kept sucking. Frankly, it seems like a huge oversight in a $240 helmet.
    Otherwise, the helmet is super breathable and bombproof. If it fits, seems like a great option. I went with the Giro Switchblade which is also DH rated, has a removable chin bar, and is much more comfortable in size L. And after a couple of rides, I have found that with some pad adjustments it's not as hot as a lot of reviewers complain.

    I am Korean. Head circumference 60cm.
    Rampage Carbon helmet xl size I bought.
    The pro frame should buy Large, but should I buy Xlarge?

    Unfortunately the size chart CC has is not for the Proframe. I have a Large and has a sticker inside that sasy 58-61cm. It comes with different pads to make the helmet adjust to different head sizes. The Fox website lists the sizes in inches, here they are:

    s20.5" - 22" m 22" - 23.25" L 23.25" - 23.75" xl 23.75" - 25.25"

    But if you convert them to cm the L is 59-60cm. But my Large has a sticker that says 58-61. If I were you, I'd go with the XL to start because the size chart would put you at an XL.

    Savin' your noggin from a loggin

    • Fit: Runs small
    • Size Bought: large

    People call me Darth Vader in this helmet. Too bad they only had black.

    Best DH helmet I have had.

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: Medium

    As a DH racer who has gone through helmets each year this one will stick around. Light and the venting is stupid awesome. Never hot, went down at Trestle and again at Steamboat this year on some Double Black shit and the helmet did its job. Also have had a buddy who smoked a rock after going airborne and his head was fine.

    Great so far

    • Familiarity: I've used it several times

    Love it so far. I do not always need a full face, but the proframe is light, cheaper, and more airflow then anything else.

    Unanswered Question

    When are you going to have blue or teal colors available in medium size?

    Not a great fit

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: Runs small
    • Size Bought: XL

    Went based on the size chart for this one and it did not fit well at all. It has no adjustment like you will see on the Giro Switchblade besides some thicker pads. The chinbar doesn't give you much room. It is a great lightweight helmet which gives you the security of a full face with the weight of a half shell.

    The Switchblade is different because it is convertible. The Fox and most full face helmets are not adjustable except for padding changes which is why they often come in more sizes. I generally wear Giro helmets and found the shape of the Fox helmet to be very similar to Giro.

    Nice airflow, light

      I was able to try this on at my LBS. Unfortunately they didn't have my size and said it would take 3 weeks to order. Overall fit is great, I have an XL. Airflow is really nice. Even on 85F days it doesn't get too hot. Chin strap feature is really nice. Both Fox and 100% goggles fit great and I haven't had any problems with positioning.

      Unanswered Question

      The claimed weight in the tech specs is 10.4oz. Can this be true? That's less than half the weight of my super 2R

      As an update to my previous review, the ventilation on this helmet is awesome. I kept finding myself trying to put my water bottle up to my mouth since it was so comfortable I thought I was wearing an open helmet while riding lifts at Deer Valley over the weekend.


      Full face protection, half the weight

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

      This thing is awesome. Very comfortable. It honestly feels like you are wearing a regular half shell helmet. This is a great option if you are looking for some added protection but maybe don't want to rock a full on DH helmet.

      That being said I think if you are running chairs all day hitting massive features you might still want a beefier helmet. This is DH certified, including the chin bar, but it doesn't have the same padding as other full face helmets.

      Still great and would definitely recommend.

      Game Changer

        Fox really stepped it up with the introduction of the Proframe helmet. Super lighweight without any reduction in protection, and looks like a normal helmet compared to some other options out there. As far as protection, it checks all the boxes in terms of Mips and DH certified chinbar. As far as ventilation, the Proframe sets a new standard for pedaling in a full face helmet. I was really impressed with the minimal air flow restriction while wearing this helmet while climbing, and didn't feel the need to unlatch the helmet due to excess heat. The helmet also includes additional pads to help dial in the perfect fit, which was a welcome addition. I ended up utilizing the thinner cheek pads to provide a bit looser fit for my preference.

        Game Changer


        • Familiarity: I've used it once or twice and have initial impressions
        • Fit: True to size

        I was between the proframe and the rampage comp and decided on the proframe because it is a bit lighter and mainly MIPS. If I am buying a full face I want it to be as safe as possible. The Rampage was a bit more comfy but I will take the added safety of MIPS
