Why We Like The Lazer G1 MIPS Helmet

We choose the G1 MIPS Helmet for our road rides because the ventilation and aerodynamic profile make it an efficient option for logging miles. 22 total vents keep us cool and Lazer’s Rollsys retention system provides a 360degree fit and comfort in a lightweight design that adjusts from the top of the helmet and away from our hair. For added peace of mind, a MIPS layer in the G1 redirects rotational forces in the event of an impact.


  • Superlight road helmet with MIPS protection
  • Advanced Rollsys system adjusts for 360degree comfort
  • Compatible with Lazer’s Aeroshell for aerodynamic and weather advantage
  • 22 vents enhance cooling by pulling air through the helmet
  • Includes race and comfort pad options to suit your preference
  • Lazer Universal LED attaches to the rear for visibility (not included)
  • Item #LZRG01J

Recommend do not purchase

I've put it through the wringer

Helmet has design issue with front padding, wears out very quickly and neither Competitive Cyclist, nor the Mfg stands behind it.

Nice Lid!

I've used it several times

Super lightweight, high quality lid. Only question will be how durable it proves to be as the rear cradle and mech are very minimalist.

quality helmet.

I've put it through the wringer

This is my third Lazer helmet, and the highest rated Lazer road helmet at Virginia Tech. I love their tightening mechanism. I have long hair, and it's much more comfortable than the dial at the back. Even without it, though, it pinches my head less than the dial at the back. This helmet is lightweight and comfortable. The only downside is that the color selection is kind of bland. I would have liked one safety color, since I use this for commuting, or something other than primarily black unless it's white.

good helmet but some issues for me

I've used it once or twice and have initial impressions

glasses wouldnt store in the helmet well and the cinch mechanism got in the way of wearing glasses. Also cinch was hard to tighten down enough. eveything else was good about the helmet, only used a few times before returning

Fit is Weird

I returned this product before using it
Size Bought:
5' 10"

Returned before using. I really wanted this helmet to work since it is rated very high on Virginia Tech. I have hair and it keep getting caught in the front of the helmet. Also, suggestions about the fit being an odd shape I agree with. Helmet was tight from front to back, but gaping on the sides. Way to much play to have the added pads fill. Loved the bright color!

Requires hair

I returned this product before using it

Seems like a great helmet: light, highly rated etc. But the helmet has a thin hard plastic attachment that fits around the back of your head which holds the helmet in place. This part of the helmet is integral to the design but only appears in one of the pictures advertising the helmet. Without hair the plastic is instantly uncomfortable - deal breaker.

Beautiful helmet, just didn't fit

I returned this product before using it

I ordered the light blue sunset in size Medium at the recommendation of CC customer service. I currently own and love the Z1, but it's now over 5 years old and in need of replacement. I measured 56cm, and normally take a small in helmets (my Z1 is a small) but that wasn't available in the G1 in this color. Since my size puts me between the Small or Medium, customer service checked and said the shape of this helmet (more oval than the Z1, which is pretty round) would still fit me. It is even prettier in person, but when I put it on, it definitely looked a bit big to me. I had to move the sizing wheel almost to the tightest level, and it fit, but there was a large gap in the back of the helmet between the plastic frame that tightens down and the helmet itself. I just felt that it had unnecessary room and it really looked like I should go with a small. I'll have to wait until Lazer restocks it and will try again. Even the white in a size small is out of stock here :(.

Long hair gets caught in MIPS buttons

I returned this product before using it

This helmet was easy to adjust and get to fit on my head. Unfortunately, the front two MIPS buttons snagged my hair (long, tied back in a ponytail) no matter how careful I was about removing the helmet. Also FYI, this G1 MIPS size medium weighed 271 grams on my scale, not 235 as advertised (Other helmets I'ved weighed have weighed true, this scale is accurate). Maybe it's 235 grams without the MIPS liner?

You won't even know it's there

I've used it several times

The first time you go to pick it up you'll be amazed there's even something in your hand. Weighing in at just 235g it's one of the lightest helmets out there. Personally, I've had a lot of trouble fitting most helmet brands, but the Lazer G1 Mips helmet is finally an exception! I'm always worried that the retention system will just pull the helmet backward on my head, but luckily, once I made the macro adjustment inside the helmet, the outer adjustment worked beautifully. Because the retention system falls down a bit lower on the head than a lot of other helmets, it can get in the way of sunglasses that have really straight arms. My Smith sunglasses interfere with the retention bands under the back of the helmet, so they won't stay in place on my face, but I'm probably an odd case. Anyway, having to swap out for different shades is a small price to pay for such a nice helmet. The side straps are sufficiently adjustable as well and are not at all uncomfortable once you set them right. My one gripe with the helmet is that there is no sunglasses storage factored into the design. I've come to love the ability to quickly take my sunglasses off and store them tightly and securely by sliding the arms into the helmet. For various reasons most riders don't keep their shades on for 100% of a ride, so it's a nice feature to have, but one that I can look past for a helmet as light and comfortable as this. It's sleek (doesn't appear bulbous), the colorways are stylish, it looks pro, it'll help make you feel faster, and it's extremely lightweight. I've only been able to ride outside so many times this winter with it but I'm already picturing so many epic rides with this beautiful helmet atop my noggin.

Safety and Excellent Fit Rolled into One

I've used it once or twice and have initial impressions
Size Bought:
5' 9"

Hey if you are looking for one of the safest helmets out there for a bicycle look no further!! This is one of the highest rated helmets by the Virginia Institute of Tech and it looks great as well! I'm very particular about my helmet safety and fit, if the helmet doesn't fit just right i get a massive headache after about an hour or so on the bike. I've had Lazer helmets in the past and they have worked quite well for me and this G1 is no exception. I haven't had it out on the road yet (to much snow) but did test it out on the trainer it no headache!! I checked the size chart, measured my noggin and ordered and it fits spot on! You only have one brain do yourself a favor pick up a safe helmet add a Protect+ plan just in case you crash or drop the helmet and get it replaced no questions asked!!
