Giro Aeon Helmet Review

Just like my previous review on the Giro DND gloves, helmets are also very specific to the style of riding you do. You have full heavy face helmets for downhill, with the most protection, you have trail riding helmets that have less protection, and then you have a race helmet. I would like to say that race helmets have superior protection, however the goal in such a helmet is weight and ventilation with protection on the back burner.  The way a specific helmet fits the melon should be the main selling point, and for me when trying on various race helmets the Giro Aeon helmet fit me the best.

The Giro Aeon is made up of EPS foam which in general, all bicycle helmets are made of. What Giro does is add there Thermoformed SL Roll Cage reinforcement. Giro Claims that this shell is what holds the helmet together and gives extra strength in the case of an accident. The extra strength makes it possible to add so many vents, 24 of them.  The Thermoformed SL roll cage and the standard Polycarbonate shell act as a double reinforcement in the case of a tumble.

Giro also incorporated these technologies to create their maximum air flow called Wind Tunnel Ventilation. The Ventilation system combines these vents and the internal exhaust chambers. These chambers act to remove the heat out while the vents bring in cool air, creating a comfortable temperature in the warmest of days.

Giros tightening system, the Roc Lock 5 is a very easy system to tighten and loosen the helmet by very small intervals, creating just the right fit.  Giros Proprietary Three Size Super Fit system is by far one of the best features of this helmet. Because all of our heads are shaped differently Giro incorporated the Three Fit system to allow the Roc Lock 5 to move up or down on the back of your head.

Just recently I got to test out my new Giro Aeon helmet in the heat of Arizona for the Arizona Trail Race 300. I couldn’t have picked a better time to test the helmet as one of Giros main selling points of the Aeon is the Ventilation. Before the race I tested out the Rudy Sterling helmet and Lazer Helium, both felt as if the helmet just sat on top of my head, rather then fitting snug around my head.

The Aeon has plenty of room for cycling caps.


  • The feature that sold me was the fit, it almost feels as if the Aeon is custom fit to my head. 
    • The Roc Loc 5 and Three Fit systems combined to make a custom fit.
  •  in 95* temperatures the heat on my head was the least of my worries, Giros Wind Tunnel Ventilation worked as advertised, bringing much needed air flow through the 24 vents.
  • Comparing the weight of this helmet with My Giro Phase is a joke. The Aeon is the same weight as my Iphone with case.
  • The X-Static pads inside the helmet are very comfortable and stay in place.
  • The chin strap is very simple and light, and very easy to adjust.
  • The sleek color and design is rad, while keeping it modest. Giro does however have flashy designs available if you’re in to that.


    • The ultra thin Roc Loc/Three Fit plastic system seems very breakable.
    • The weight is nice and all but the Aeon might be toast after a single fall.
    • Price poin, one of the most expensive helmets on the market.

    You can see how thin the plastic pieces are.

    After wearing the ultra light Giro Aeon for 400 miles, I’m sold that it is a top of the line race helmet. Giro throws all their bells and whistles in to a relatively simple helmet. Compared to the helmets in this class, the Giro Aeon is by far the superior helmet– that is of course if you can throw down anywhere from $250 to $175. Currently the Aeon comes in three sizes and 8 different color options. Check out Giros website to take a look.

    Giro DND Mountain BIke Glove

    As an avid mountain biker, gloves are essential. They protect your hands from branches, falls, and the elements. The kind of rider you are will determine the type of glove you should buy. Being a cross country rider really makes it an easy decision. Simplicity and durability are my key attributes and the Giro DND glove has got it covered.

    The DND glove is made of a super stretch moisture-wicking top, and Giros synthetic Clarion leather technology on the palm and fingers. Giro claims this specific material is extremely durable while not being too heavy duty in creating a perfect mold to your hand. Giro uses a three piece palm construction to aid in the fit of each individual size glove.


    • Giros Super Fit Engineering makes for a outstanding fit to your hand creating a natural feel on the handbars.
    • Giros Clarion Leather is not bulky and it doesn’t bunch up like some other gloves.
    • The strap around the wrist is not to tight and there is no constriction in the fingers. (I can even use my I-phone with the glove on.)
    • The stitching is very tough. With a few falls, I have yet to notice any tearing at the seams.
    • The wiping surface on the top of the thumb/hand is highly absorbent and very soft.
    • The design is sleek and available in 4 different color options.
    • Price point 


      • The silicone fingertip print on both pairs of DND gloves I have owned have slowly started to peel off of my middle and index fingers.
      • I like the specific design of my Black and Tan model, but I do not like the esthetic of the glossy finish on the reinforced finger.
      • Don’t let your dog get a hold of them, they will tear them up!

        This Giro DND is an overall perfect fit for a cross country rider, The main idea is durability and a snug fit,  Giro nailed it. The DND is great in warm conditions but the black top of my
        specific model conducts heat perfectly for those cooler rides. Although the silicon print has started to wear off, I don’t know a glove manufacture that can keep the stuff on. I bought a large initially and I thought it was a bit tight. But with Giro’s Super Fit the glove formed to my hand perfectly within a few rides. For the price of around $25.00, with 6 sizes, and 4 models the Giro DND glove just might be the best mountain bike glove I have ever put on.
