Troy Lee Designs - A3 Halo MIPS Helmet (MTB)

A3 Halo MIPS Helmet is a Troy Lee Designs mountain bike helmet built for enduro and bike-park riders. The A3 shape suits aggressive trail riding with an emphasis on day-long comfort and modern mountain bike coverage. It is shaped around dependable protection, ride comfort, and the clean finish Troy Lee Designs helmets are known for. The Halo treatment gives this helmet a more individual feel than a plain solid option. The MIPS-equipped build adds another layer of confidence for riders who prioritize modern helmet technology.

That combination of coverage and ventilation makes it a natural match for riders who move between trail networks, rocky descents, and bike-park days through the season.

Why We Like It: it gives riders a stable feel on rough descents without turning every climb into a chore.

Why It’ll Work for You: It works well for riders who split time between trail loops, enduro stages, and lift-served laps and want one mountain bike helmet that feels ready for all of it.

Variants / Options: multiple sizes and colorways available; check the selector for current stock.

Really great shirt, really thick material
An unexpected pleasant surprise. Really nice quality, minimal shrinkage, and very few wrinkles out of the dryer. Nice, comfortable fit, and for big-but-not-tall guys, the fitment is very presentable. Sleeves aren't crazy long, and the shirt itself isn't so long that you feel like you're wearing a dress. These aren't complaints, but I do want to share two notes that were important to me: 1. If you want a breast pocket, be sure to select the right shirt. There are two different versions, and it's not particularly obvious which is which. 2. The material is thick. Really thick. So the shirt is pretty heavy, and it doesn't breathe very well. For me, this is unquestionably a winter shirt. If, like me, you tend to run a bit warm, this shirt can make you feel like you're wearing a parka.

Great Value from Amazon Essentials
I can’t believe the quality of this shirt given the low price I paid for it. It fits perfectly, looks impressive, and is very comfortable. The shirt has survived two washes so far and looks as good as new. I couldn’t be more satisfied with this purchase.

Too large, length too long
Size: Medium, Color: Light Grey Vertical Stripe
Runs large, and the length is far too long to wear untucked like in the photos. Always wear a Medium, this fits like a Large. Length of shirt is long and obviously made to be tucked in. You would look ridiculous if you left it untucked. Dont understand why companies still insist on designing shirt to be tucked in when most people dont wear it like that these days

Traditional Grown Man Shirt
Size: Large, Color: Light Grey Vertical Stripe
Great cotton, classically-style button down shirt for guys not wanting anything slim fit, this shirt size is legitimate. It’s a nice heavyweight cotton shirt. I don’t think I’d say it was wrinkle resistant but it doesn’t take much effort to press this garment.
