    Bottom Line:My dad bought me this helmet for me a couple of years ago as a birthday present. I ride pretty hard and its taken a few solid licks, but is still in great shape. Just recently I noticed that the RocLoc was broken. So, I took into a LBS and they gave me a number to call the Giro Custumer Service. I told them what the problem was and about how long I'd had the helmet. No questions asked, they shipped me a new RocLoc for free. Now, my helmet is as good as new and ready for another season of abuse.

    Strengths:Good protection, fantastic removable insert, good vents, touugh helmet.
    Weaknesses:None.
    Similar Products Used:Specialized S1, HRC something ...
    Bike Setup:Many bikes ...
    Bottom Line:I think this helmet is amazing. It is comfortable (for my head), it has good ventilation, and provides a great level of extra protection compared to pure xc helmets.

    The foam insert is one piece, and can be taken in and out easily, so you can wash it. Other helmets have individual foam inserts that seem to fall apart when you take them out. Great long lasting quality.

    If you look hard, you can also regularly find them on special.

    Similar Products Used:Giro Havoc
    Bike Setup:Makes no differance for this review.
    Bottom Line:Good helmet that fits well and is very comfortable. The RocLoc system makes it easy to adjust the fit and keeps the helmet in place on your head. Mine soaks up sweat and eventually lets it drip down over in to my eyes and on my sunglass lenses making it harder to see. I have to push the helmet against my forehead a couple times a ride to empty out the sweat that has collected to prevent that. Overall really good helmet that's pretty expensive with one annoyance.

    Strengths:It is so far the most comfortable helmet that I've used. It's very comfortable and sometimes you'll never know you're wearing it. The killer looks! It's light weight for an AM helmet. It cover the back of the head for added protection
    Weaknesses:Not as light weight as other bell and giro middle priced helmet, but still light enough though. Expensive! (you get what you pay for)

    Bottom Line:I've been using this helmet for more than a year and crashed several times, saving my melon. I got mine in olive and it just looks great. Well, the matte black is also my next option. I like the visor which is the same color as the helmet, not like those cheap looking black plastic visors. It can also be moved up and down if you want a wider view. The staps doesn't come loose and the RocLoc 4 system is a good design. For me, bell's locking design is easier to use. I would recommend this helmet for those into aggressive XC and All Mountain riding.

    Strengths:Looks clean, better construction than my first Giro helmet eight years ago (technology marches on, hm?)
    Weaknesses:None yet
    Similar Products Used:Giro something-or-other
    Bike Setup:Cannondale Bad Boy Disc
    Bottom Line:My triathlon-competing uncle became totally sold on wearing bicycle helmets when he had trouble unclipping from his bike while parking it curbside and fell, hitting his helmeted head on the sharp edge of the curb. That helmet was trashed, but his head was fine, illustrating that even zero-speed falls & flops have the potential for serious injury. These days, I feel weird if I'm ever riding without a helmet.

    For me, at the time, selecting a helmet was simple -- try everything on and see if it fits properly. I tried probably six different models from three manufacturers (Bell, Giro, and Specialized), and this was the one that fit the best, especially over the pointy crown I have at the top-center of my head. Slick color schemes and super-aero shapes don't matter if it hurts. It's only a side bonus that its flat black color matches the Bad Boy that I bought at the same time.

    A couple reviews back, Kalikiano Kalei gave a lot more info than I would have thought of myself. He makes a lot of sense, too. This Xen has a rounded shape that covers much of the back of the head, but there's not much to poke out and catch on things. Aero-blown shapes, IMO, don't matter a whole lot at speeds below 30 mph anyway; and besides, my torso creates more drag than the trailing half of a mere bike helmet.

    The rear strap mechanism is simple to adjust, and it doesn't appear to require engagement/disengagement when taking the helmet on & off. My older helmet's rear strap was partially mounted using glue & Velcro, but I'm pleased with the actual mechanical mounts on the Xen (indeed, on most modern helmets). This should turn out to be a pretty durable helmet.

    Duration Product Used:More than 3 years

    Purchased At:REI (mainland)
    Strengths:Structurally strong design with good shell integrity and satisfactory shell/foam bonding. Easily adjusted suspension and fastener. Excellent occipital coverage (rear of skull) for protection of brain's visual lobe. Very adequate cooling for most applications. Most important positive feature is rounded external rear shell design that lacks sharp "swoopy" protrusions that can snag during a fall and cause hyperextension of neck (causing severe cevical spine injuries)--kudos to Giro for this feature! This is a greatg helmet for those with heads that are longer ("watermelon" shape, as opposed to roundheads) in fore and aft dimensions and slightly narrower side-to-side. Helmet stays on head securely in almost all situations. Summary: an excellent and much overlooked and underrated helmet for both MB and street aps.
    Weaknesses:Lack of high visibility shell colors to choose from. Visually bright orange, red, or lime green colors should be available! Yeah, I know: dark is "cool", but being easily seen while using a helmet on the street is healthier (stay alive longer, brah!). Hotheads might want a bit more cooling, but a sweaty head is far better than a busted one, brahs!
    Similar Products Used:Most other helmet designs (Bell, et al) over a 15 year period. Few are better for a wide range of bicycle protective applications than the GIRO Xen, in my professional opinion (as a specialist in military aviation life support technology and crainial protection safety).
    Bike Setup:Too many to list.
    Bottom Line:The Giro Xen bicycle helmet was designed originally for mountain biking and cyclo-cross applications, but it is actually also one of the very best designs obtaininable for street and bicycle commuter applications as well. Protective helmet studies have shown that today's 'aero-styled' bicycle helmets, with their stylish "swoopy" protrusions at the rear, are actually potentially unsafe in crash situations wherein those same jutting protrusions may snag during a fall and traumatically hyperextend the wearer's neck. The result of such a circumstance is easily (and usually) a broken neck (cervical spine fracture or complete separation--i.e. paralysis). Helmets that have a more rounded rear section with a smoother external aft shell surface are far less prone to such catastrophic accident circumstances during falls and other serious dumps. This is generally not a well known fact among bicylists who would rather look 'cool' than 'safe' (few want to look like a 'safe dork', understandably--it's human nature). Those of us who specialise in protective helmet design for all applications (aviation aircrew, automobile racers, bicyclists of all persuasions) understand the need for more smoothly rounded shells that offer less opportunity to snag during vigorous activities. Although I use my Xen for serious mountain biking on Hawaiian volcanos (cyclo-cross, too), I also have a Xen I use exclusively on the street (for both road-racing and commuting). I feel it is one of the best overall bicycle helmet designs to come along in a long time and I heartily recommend it to anyone ionterested in maximising personal safety on any kind of bicycle activity! Giro really got it right with their 'XEN' design!

I sent a e-mail to Giro explaining the issue and to this moment, I have no answers. This helmet has not been used constantly due to my job, maybe just 5 months totally in the 16 months that I owned.
    Well for me the worst part has been the Client Service, no answers, even for say: "sorry I can't help you". For me this say many from a company. Not like others as Crank Brothers or Santa Cruz, where the CS is awesome.

    Bottom Line:The most comfortable helmet I have ever tried on. Good protection without looking too goofy. the best part about it is the great abundance of padding around the front, which helps a lot in keeping sweat out of your eyes. My old helmets both wore out the pads rather quickly, and new pads were not to be found,even thoough I have heard they are replaceable. Since both old helmets were satisfactory otherwise, If this new Xen wears out just as quickly, I will never buy another "expensive" helmet again. I'll just buy a new cheap one every year. We will see.
