Uvex XP 100 Review

Helmets Pro Reviews

Reviewed by Brian Mullin http://www.gramslightbikes.com/

The uvex (pronounced ew-vex) xp 100 helmet has been my main noggin protection for three months, and I have found it to be lightweight, comfortable, easily adjustable, with a large brim and excellent rear protection. The German made helmet has a plethora of features, that add not only to its safety, but to the comfort and usability of the wearer, plus I liked the wicked skull graphics.

The xp 100 has a lot of nice features, mostly in regard to the fitting and adjustability system. It uses their proprietary IAS 3D+ ring (Internal Adaptive System), which is a rear mounted dial driven adjustable retention system. The system allows easy circumferential (length and width) and height adjustments, and can accommodate a wide range of head sizes, and headgear thicknesses used for inclement weather conditions. Simply twirl the dial, and the system tightens or loosens around the head.


The chin strap, named the Monomatic, is a button and ratchet closure system, which allows easy micro adjustments, and includes a nice wraparound pad for comfort.


There are extra large vents for cooling, and the front ones feature mesh panels to stop bugs from getting sucked into the inner helmet cavity. The straps come through the shell and are secured by toggles on the outside. A neat feature is the ability to swap the toggles for special ones that let you mount uvex LED’s to the helmet – rear-facing red centrally located at the back, and two forward-facing white ones on either side at the front.


The helmet is constructed with the industry standard in-mould microshell, which has a thick inner foam and a thin outer plastic protective shell. The foam is made with the shock-absorbing polystyrene (expandable polystyrene foam or EPS) material. The outer shell is split into two large pieces, and is made from the Makrolon polycarbonate material, which is the same impact-resistant material that Uvex’s eyewear lenses are made from. The shell has been extremely rugged, and has shown no signs of wear nor abuse, which is a testament to the tough Makrolon material.

For technical fodder refer to Makrolon, Polystyrene 101, and helmet safety.

    THis helmet is AMAZING! I have the Black Matte color so the stains dont show and the chin strap never pinched my beard or neck at all. Everybody’s head is different so this may still be an issue for some people. VERY VERY comfortable as well, this is something that I never had in any helmet.

    Great review by the way. This is a very under-reviewed helmet, which is good because not a everyone knows about it, unlike some of the over-marketed Giro stuff. Dont get me wrong, Giro ricks too, but this the Uvex XP100 stand alone… for now.

    The chin strap issue was a very rare, and I had to come up with something to nitpick about

    Been eyeing one of these and the new Lazer Oasiz. Seem to have a similar method of tightening (IAS and Rollsys) but was wondering if anyone has actually tried both retention systems and could comment on any differences? Ive tried my buddies Uvex and it is so much more comfortable than my Xen. Nice review.

    I normally wear a Giro Large but when the Xp100 arrived I found it was too narrow for my head and the chin strap was too short. It’s such a nice helmet that I gave it to my son. I really wish it would’ve have fit me.

    I called the distributor in the US and they told me that the helmet was very narrow and I wasn’t the first to have this issue.

    I wear large also, and it fits fine, but I must have a oblong head! I also multiple inches of chin strap left, but I don’t have a tall head?
