## Description

desertcart.com : Troy Lee Designs A3 Adult Mountain Bike Trail All Mountain Helmet W/MIPS, Fang Dark Blue/Burgundy, Medium/Large : Sports & Outdoors

Review: Great helmet! - Buying my first helmet in a good while since we're getting into mountain biking. Some major improvements have been made in helmet tech over the years is what I'm finding! This helmet comes highly rated from Virginia Tech (they do impact and safety ratings that are highly regarded from what I can tell). Love the design and fitment. I have a small head so I got a small bit I did measure to make sure since I wasn't getting fitted at a store. The clasp took a second to get used to, but I love it and it can be used with gloves easily while still feeling secure. It came with several padding options and the visor is nice. Love the adjustable clasp at the back and adjustments on the side straps. Great looking helmet - light and breathable. Super comfortable. It's important to protect your brains y'all, buy this helmet!!
Review: Great quality, great fit, teens will wear! - My son worked to buy himself an electric dirt bike but needed a better helmet. As a nervous mom, I wanted to make sure that he had a good one BUT it also needed to pass the 'looks cool' test. I researched online and saw that this helmet was rated a 5 star by the Virginia Tech helmet ratings (which I guess is the expert). That rating made me feel really good. He loved it from the minute he opened it for Christmas. You can tell it is high quality and it has good padding. My son has a larger head so getting helmets to fit is not always easy. This helmet fits well, is comfortable, looks great and matches his bike. He is happy to wear it on the trails, which makes me happy!

### ⭐⭐⭐⭐⭐ New is better!
*by M***N on June 15, 2026*

Comfortable. I was concerned extra coverage would be warmer, but it’s not, it’s great. Newer design allows my glasses to fit without pushing on my ears, something that I felt with the older A2 model.
