    • Literally saved my life... with style!
Review Image by Peter Peter
I cannot recommend this helmet enough. Between the Mips, the sure comfy fit, the ventilation, the sturdy build... I rode all day at Loon Mountain and never once felt hot. I ordered a Large, based off the sizing chart, and it fit like a glove. Awesome field of vision too. I ended up crashing out pretty hard after not landing a gap jump, and the ER doctor said this helmet (plus a little dumb luck) was for sure the reason I'm still alive. If I could thank the crew at TLD I would shake their hands. You will absolutely NOT regret buying from these folks! ... show more

    • Great TLD quality
Color: Lines Black / Red Size: X-Large
Review Image by Brad Brad
Super light weight, more comfortable than my old D3 carbon, MIPS is a plus. I got an unbelievable price from seller but my helmet bag didn't come with the extra visor that all my other TLD lids came with. Not a huge deal, but a bummer. A few little blemishes but I paid 50% less than MSRP.

    • Best helmet I've owned. 5 stars
Great protection, mega upgrade over my last full face. Fit a bit snug at first, though once I broke it in it feels super comfortable. I've owned it for 2-3 months and only has scuffs from small-big crashes. Paint has chipped from an accidental drop though I filled it in with some nail polish. Holds goggles super well. Cool design and looks stylish. Also got it 55% off of retail and is very nice. ... show more

    • For 250$ this is a buy, 500 absolutely not.
Color: Lines Black / Red Size: Large
Bought this because Amazon had these on sale for 250. Fit is great, weight is light, honestly very comfortable with cutouts for headphone speakers. HOWEVER, comparing this to my old Troy Lee, the quality is nowhere near what it use to be, lots of errors in the wrap (it’s not all painted) but again for 250 this is a great deal and I doubt you’ll find a better helmet. If you’re paying full price (550)..don’t. ... show more
