Review: Lazer Cosmo Helmet

The Cosmo from Lazer is fantastic lightweight helmet for those looking for a step up, but not ready to commit to a full aero helmet. By Emily Conrad-Pickles

I was super excited to try the Lazer Cosmo helmet out. I’m a regular cyclist and despite doing a fair amount of racing (triathlon) to a decent-ish standard, I’ve never splashed out on the full aero helmet.

Don’t get me wrong, when I race, I always wish I had one, and sometimes borrow one, however, there does come a point when you have to draw a line with kit, and for me, the aero helmet didn’t make the cut.

Well, this is where the Lazer Cosmo helmet comes in, the clever bods there have combined all the elements of a high performance helmet in one – and have created their lightest helmet ever – just 225g.

The helmet looks like a stylish every day road helmet, but with sports additional features such as the removable aero shield and an integrated wing at the top of the helmet.

The aero shield is a see-through cover that encases the helmet. From afar, you would not know that the cover was there. I am thoroughly unconvinced as to whether aero helmets really make a difference, however, mentally they do so that is half the battle!

The downside to the shield is that it does get a little toasty when it is hot and when it rains; it is quite noisy (although your head does stay dry). You’ll need to leave it somewhere to dry if you do take it out in the rain as condensation builds up and I would worry that if you don’t dry it out properly it may get a mould build up.

Lazer boast 31 vents in the helmet, making it the best ventilated helmet in their range, however guessing that this is when the shield is off.

Other features include an advanced rollsys retention system that uses a thumb wheel on the top of the helmet (to adjust the tightness) and an adjustable “headbasket” which allows you to put the helmet in 5 positions (handy for the old ponytail). I found it extremely comfortable and very easy to adjust.


I thoroughly recommend the Lazer Cosmo helmet. It’s not an entry-level helmet but if you are on the market for a new helmet, to step up you cannot go wrong. Light, comfortable and good looking.

Pros – lightweight, comfortable and stylish.

Con – tricky to work out how the aero shield is removed.
