Item # POC0106

Better protection.

If you've ever felt that helmet designers placed too much attention on creating models that were too light and too aero for your tastes, then consider the POC Trabec Helmet. It's designed for mountain bikers or anyone who wants greater coverage over the ears and around the back of the head. The goal was to increase safety without sacrificing comfort and performance.

The Trabec fits more like a skateboard helmet, and this way it envelopes more of your skull. The fit can be custom tailored, and since it offers more coverage, the potential for movement when your head strikes the ground is less than smaller helmets with less coverage. Thinking about the way we wreck on trails, there is a greater chance for a variety of trajectory -- forwards, sideways, even backwards. When you get crazy, crazy things happen. So to protect your brain you need to cover your skull.

POC builds the Trabec Helmet as a single layer system. It has a polycarbonate shell that acts as the first defense against impact energy. It spreads the impact across a greater area so that the EPS liner can further absorb and soften the blow and protect your brain. Inside the foam core is an aramid net. Its purpose is to hold the foam together and resist chunking under massive, high speed impacts (like rebar in concrete). It's designed as a multi-impact system, so the helmet can survive more than just a few connections with the terra firma.

POC punches sixteen large vent holes in the shell, so you'll get plenty of airflow on hot days. An adjustable visor also helps on those sunny days to protect your eyes from glare and bright skies. A size adjustment system at the back allows you to snug it down for a perfect and wiggle free fit.

The POC Trabec Helmet is Black/grey and is available in three sizes -- X-Small/Small, Medium/Large, and X-Large/XX-Large. The pads inside are treated with Polygiene. It prevents bacterial growth, is eco-friendly, and is perfectly safe next to your skin. Since the bacteria can't grow on the pads, they'll last longer, require less cleaning, and smell way better.

  • Aramid-reinforced EPS core provides protection and greater durability than tradition cycling helmets
  • Extended side and rear coverage compared to traditional helmets for more complete head protection
  • 16 shaped vents guides air in, and around the helmet for excellent cooling and ventilation
  • Easy-to-adjust anatomic fit system holds helmet in place providing long-ride comfort
  • Polygiene anti-odor wipe included to prevent a foul smelling helmet
  • Adjustable visor helps to keep sun and mud from inhibiting vision

  • Aramid net inside EPS foam layer
  • Super-tough polycarbonate shell
  • 16 vent holes
  • Adjustable visor
  • Extended protection over typical helmets
  • Adjustable fit system

nugget saver

  • Familiarity:I've put it through the wringer

i don't crash too often, but when i do i crash hard. This helmet has saved me from a few concussions. Has a comfortable fit, good weight. and i like the look and visor. Ive busted it off a few times but it just pops back into place.

nugget saver

covers all bases

    bought this for a friend and she has loved it, lots of protection where needed fits small heads quite well! breathes great and doesnt dump all the sweat down on your face. only minor complaint is that the chin strap will loosen up on its own from time to time, so it does have to be adjusted every once and a while, but is it is well worth owning for the protection you receive

    happy noggin!

    Awesome picture Sheena !!!

    Very protective!

    • Gender:Male
    • Familiarity:I've put it through the wringer

    I fell hard on a rock face at about 20mph. Broke C7 in my neck, chipped a tooth from my jaw slamming shut and sprained my wrist. ER doctors were amazed that I didn't have a concussion or any wounds to the face or head. This is a very well designed helmet offering great protection. I will probably buy another when I'm able to ride again.

    Very protective!

    That is crazy William! Glad you were wearing this and it worked!


    Great helmet!

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

    I MTB off-road/trails only and was looking for a helmet that better covered the back of my head. This one fit the bill and looks great. Comfortable with plenty of adjustments to ensure a snug fit. Super glad I made the investment.
    I did need to exchange an L size for XL (my head size was right on the bubble between the two sizes).

    Best Helmet I've had

    • Familiarity:I've put it through the wringer

    This is best fitting helmet I've had. I tried a few different brands and was always fidgeting with the adjustments every time I wore it. With the Trabec I set it and forget it. It ventilates well enough for me and looks nice too. I've had mine for a few years and luckily it's never taken any hard hits but if I needed to replace it I would get another.

    When will you get this in Beryl Green?

    Best AnswerResponded on

    Hey Lupita,

    Currently we have the Beryl Green color on order. Assuming there is no delay in getting the product we should have them available around mid April.


    Protecting the Important Stuff

    • Familiarity:I've put it through the wringer

    I bought this helmet as a gift for a girlfriend, she shreds on the mountain - and even though this helmet is a bit more expensive that others, but it's safety ratings seem to be much higher - and to me, it's worth protecting her brain.

    what color is this to be exact?


    Not Matte

    • Familiarity:I've put it through the wringer

    It looks matte in the picture but the finish is shiny. Otherwise it is great.



    • Familiarity:I've used it several times

    The Trabec is a pretty comfortable helmet, with enough padding in the proper places, and a good form fitting inner shape, that has adequate room to accommodate varying head geometries. The helmet is pretty light. the ventilation is good, not as good as a cross country helmet but has good air flow. I bought the black size medium. i usually wear a size 7 1/4 in new era hats and the medium fits perfect. Has kind of a blocky look but i dig the helmet for sure.


    It Works!

    • Familiarity:I've put it through the wringer

    Took a hard fall yesterday and bounced the back of my head off of the rocks like a superball. Glad I had the protection on the back side. I really like POC products. This helmet fits very well and stays snug, but not too tight. I've had two other big head-strike falls in the last few years, and my other two helmets, while they did the job, were destroyed. The POC was dented but it was at least in one piece so I could ride back to the trailhead without too much concern about the integrity of my lid. Will be getting a replacement though. Highly recommend!

    It Works!
    Unanswered Question

    I have this helmet, now that it's winter I'm looking for a rain cover that will fit. Any ideas of something that will fit this helmet (not including a shower cap)? Thanks



    • Familiarity:I've put it through the wringer

    Nice fit - It is a bit hard to get my hair through the back... cute pink color - saved my head already as I went OTB the other day-

    Nice fit- easy to adjust ect...


    Saved My Room Mate!

    • Familiarity:I gave it as a gift but have feedback to share

    Doctor says it would have been much worse. Check out the crack through the helmet. Though it did crack still saved her noggin. Couldnt save the clavicle but, that is fixable.

    Saved My Room Mate!


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

    I was astounded by the cheap construction, especially considering the cost. The plastic covering looked like it had been cut by dull scissors and hastily glued to the shell. While the size chart indicated my head size fell well within the range of the size I ordered, the helmet was too tight, even on the largest setting.

    A much better helmet can be purchased for $100 less.


    Love this helmet!

    • Familiarity:I've used it several times

    Very easy to adjust and it fit perfectly on my head. I have had issues over the years with finding a helmet that is comfortable and I took a risk buying this one online but it has plenty of areas to adjust and feels great. Very light weight and lots of ventilation not to mention that I think it looks great! I bought it in white and love the color!

    Highly recommend!

    Above average, but not perfect

    • Familiarity:I've used it several times

    I picked this helmet up as my first mountain biking helmet, and have ridden with it several times.

    What I like:

    *white color option helps a bit with the heat

    *size XL fits my enormous head well

    *the big vents let in a good amount of breeze when I'm downhilling

    *it seems to have good overall coverage

    What I don't like:

    *the side straps tend to shift position easily if you take the helmet off hang hang it by them

    *the only thing securing the chin strap tightener is a rubber band

    *the brow pads don't do a very good job of keeping sweat out of my eyes (it's been a hot summer!)


    Awesome Helmet!

    • Familiarity:I've put it through the wringer

    I purchased this helmet after realizing my previous one was long expired and probably would not survive a minor bike wreck. I looked at POC helmets because I have a ski helmet of theirs that I LOVE! I appreciate the care they take in the adjustability of their products. The chin straps are easily modified and I love being able to secure the back of the helmet to my head so I really feel as if the helmet is part of me. I rarely remove my helmet while biking and I find this helmet is so well ventilated that if I do take it off after a climb I barely notice a temperature change. It is lightweight. I feel completely protected by the design and even though appearances shouldn't matter, I don't look ridiculous in this helmet (at least myself, my dog and my man friend don't think so). I went with the same size I ordered for my ski helmet and it fits perfectly. A couple notes, the visor does not come off which is not an issue for me but may be for some people. Also, since I don't remove my helmet while climbing I cannot speak to the ease of carrying it on a pack. The rear head adjustment is wonderful but I would be interested in a boa system if available. I didn't research that component and it may not make a difference. I happen to love the boa system in my ski helmet it might be something to look for in future helmet purchases. Overall, love this helmet and highly recommend it! POC products are expensive but for a reason. I am insanely happy with all of their products I use!


    Great Helmet

    • Familiarity:I've put it through the wringer

    We got this helmet for my wife and she has loved it.
