Duetto

Description

Duetto is the most innovative and lightest double certification helmet currently on the market. Fully certified for mountaineering and for skiing!

The name recalls the concept of dual-certification as climbing, mountaineering and skiing helmet. The design features the Stealth elegant and innovative multi-faceted shape but the construction is totally new: EPP (Expanded PolyPropylene). This foam allows a very low weight at only 215 grams, much lighter than all its current competitors. Its thickness allows great shock absorption on both the top and the sides (all-round protection).
It’s available in one size that can be easily adjusted to fit once the helmet is on. It features four integrated headlamp clips.
It is a great option for all mountain activities in both summer and winter, from climbing to skiing to mountaineering.
It comes with a helmet bag and a helmet holder to fix in on the backpack.

This is the lightest dual certified helmet available. You can see the full list of dual-certified helmets by clicking here.

Features

Features

Bike Cert (EN 1078)

The EN certification for helmets used for bicycling and skating. The major difference in testing 1078 involves needs for more head coverage and for the helmet to pass a deflection or 'roll-off' test of the impact force.


Brim

Having a brim on a helmet may be inconsequential to some climbers but they make a great additional bit of protection against sun, rain and falling debris like small rocks or verglass.


Multiple Sizes

This is helpful for those with particularly small or large heads because helmets that come in 2 or 3 sizes cover a broader range of head size. Usually these are denoted as size 1 or 2, though some brands have S/M and M/L.


Face Shield Compatible

Face shields are a part of PPE that could be handy when drilling, developing and cleaning particularly dirty remote routes. Usually only used by work at height professionals.


MIPS technology

MIPS or Multidirectional Impact Protection System is a technology designed to reduce the amount of impact force that makes it to the brain. This is accomplished by adding a low friction cap between the liner and the helmet, allowing the shell to deflect around the head rather than transfer the forces from impact directly to the wearer.  Many bicycle helmets include this feature and it is starting to be applied to sports like skiing, motorcycling and climbing. Many MIPS helmets are also EN1078 compliant.


Ponytail Cutout

So far these are only found in "women's" helmets. It's a cutout / notch area that accommodates a low hanging ponytail hairstyle.


RECCO® reflector

These are used in locating someone missing or buried in an avalanche and are becoming more common in climbing gear due to the increased popularity of ski mountaineering. Though they are more often sold as something to add onto the helmet than being built into one, some manufacturers have begun to build them in.


Ski Cert (EN 1077)

The EN certification for helmets used for climbing and skiing. This test is simpler than the EN/UIAA one performed for helmets in general, but increases the amount of force that a helmet must endure. Likely this to simulate the faster speeds involved with downhill skiing impacts versus rockfall or climber accidents. This cert becoming more common in helmets as SkiMo popularity increases and more climbers are adding backcountry skiing to their mountaineering repertoire.

Ski Cert (EN 1077)
Quick Adjust

Quick Adjust

Quick Adjust refers to the straps of the helmet. Do you want the ability to ability to "quickly" adjust the fit. This could be a dial, or other plastic pieces.

Really, most climbers don't need to change the fit of the helmet often, unless you're climbing with and without hats, or you have big hair that flattens and then requires tightening after climbing for awhile.

No
Vents

Vents

Refers to openings in the helmet body to allow air flow. Commonly found in most helmets these days, but often more so in foam and hybrid foam helmets than traditional hardshell polycarbonate shells.

Headlamp Compatable

Headlamp Compatible

Many helmets include hooks or clips for holding a standard headlamp in place, which is quite useful for the caver or alpinist. Ask any climber who has been benighted and they’ll tell you just how useful this feature can be.

Climbing Gear Reviews UK rating 5/5

The Duetto has proven to be an excellent all round climbing helmet – I can’t really vouch for it’s skiing prowess apart from a brief session on rolerskis when I’d forgotten my bike helmet and luckily had my climbing kit in the van! In terms of overall bulk it is similar to the Grivel Stealth HS and easily fitted beneath a variety of hardshell and belay jacket hoods although it is marginally ‘taller’ than the Petzl Sirocco. The one size fits all harness was extremely stable keeping the helmet securely in place including when used with a headtorch. The range of adjustment meant that it could easily accommodate a fleece hood or hat in winter whilst still snugging down on my unadorned head in summer.

The UIAA equipment standard provides a baseline for equipment performance in a test lab under controlled conditions on new equipment. Although these test conditions are relevant to the conditions encountered climbing, conditions encountered at the crags and the condition of the equipment are equally important. This recommendation from the UIAA member federation The British Mountaineering Council (BMC) provides vital equipment information that is NOT explicitly addressed in the standard, particularly failure modes of the equipment and recommendations for the use, inspection, maintenance, and retirement of equipment.
