The pulse helmet seems to have too much of a oval shape. My head measured 56 cm and the size 1 was perfect fit without the winter kit or any headgear. But pressed on the sides of my head. The size 2 fits perfect with or without any head gear.
It sits extremely comfy and snug without giving any head aches.headlamp clips look flimsy and of lower quality but seems t work fine. The back light-clip is single and doesn't hold headlamps with a battery pack on the back well, but it is possible. Ski goggles fit supperp. Best of both worlds and I would strongly recommend it.

I have now tested the Pulse Helmet with goggles both with and without the optional "Winter Kit" attached. With the goggle strap properly situated under the provided keeper tab (at the rear of the helmet), the goggles fit seemlessly. This is a great/light/comforatble helmet for backcountry skiing!

I have a large oval shaped head and even the XL was a little small, but I was easily able to make it a touch bigger with a grinding tool. Light weight, functional, good looking, the headlamp clamps are great. Too bad I dropped it on Mont Blanc and had to watch it tumble 1,000 feet down to its perminant resting place at the bottom of a crevasse. Now I need to reorder.

This is a really beautiful helmet, very well made, light, airy, comfortable, good looking, excellent fit adjustment etc....however as soon as you put a pair of standard ski googles on over the helmet it all goes to hell...the tension in the goggle strap (even if it is adjusted to a minimum) causes the plastic fit adjuster at the rear of the helmet to dig painfully into the back of your neck....very bad design. I experimented a bit, but could find now way to resolve this serious problem. I reluctantly returned the helmet for a refund as a result.

This is a great backcountry skiing/ski mountaineering helmet. It's super light, rated for climbing too, warm with the winter kit, ventilated for skinning. Totally worth it. Remember that a large portion of avalanche victims die from trauma alone. Also, you can't keep that avalung in your mouth if you're knocked unconscious. Definately a good idea and this is the best way to execute that good idea.
Definately try it on if you can.

I was disappointed by both the fit and the winter kit functionality (CAVEAT: I have not used this helmet in the field). The tension band does an adequate job of keeping the helmet on my head, but the fit is rather clunky. Given that this is the only helmet of it’s kind, I would have gone with it based on that. However, I opted to return it as the winter kit is pretty under-engineered: the insulated plugs neither friction into the holes nor adhere to the interior of the helmet - hard to imagine how they’d stay in without tape - swapping them out in the field would be awkward at best. The ear flap attachments interfere with the tension band and the chin strap (at least at my head size). There is so much slop in the closure mechanism for the holes on the front of the helmet (right over your forehead), that they only partially close.

This might be a fine helmet for spring skiing, but for winter climbing, I can’t see it working that well as an insulator.

My advice: wait for the next generation…

This is a very good helmet for skiing in the BC or any sort of winter climbing. The Winter Kit can be a little pain to install but it still only took me less than 15 mins. I think that it might be a little cold for skiing lift served on sub zero days but other than that it would be fine.

The place that it really shines is the light weight and comfort. I can't comment on how well goggle fit because I don't wear them. I have spent way to much time waiting for people to de-fog their goggles, but the helmet works fine with glasses.

I would recommend buying this with the winter kit. However even without the winter kit it is too hot for summer climbing.
