Troy Lee Designs' New Mountain Bike Helmet, the Flowline Helmet

I’m going to introduce a new mountain bike helmet that just arrived.
It's the Troy Lee Designs Flowline Series Flowline Helmet.
It's a completely new model.
Previously, there were A1, A2, and A3 models, but it seems the A1 and A2 have been discontinued.
In their place, the Flowline series has been released.
Among half-shell helmets, the A3 is the high-end flagship, and previously there was an entry-level A1 Drone model. This Flowline helmet will likely be the replacement for that grade. It's a helmet that offers both safety and cost performance. The A1 Drone didn't have MIPS, which is standard these days, but this Flowline helmet comes with MIPS from the start.

The visor is adjustable to three positions, and I prefer it in the highest position. This helmet is equipped with MIPS (a safety system to reduce impact), and the yellow part indicates the MIPS. MIPS helps dissipate impact by allowing slight movement, reducing damage. Additionally, this helmet has an adjuster that surrounds the entire head, increasing the fit. It has 14 ventilation holes, allowing you to adjust airflow. The ear and strap positions can also be finely adjusted to customize the fit. For safety, it has received a 5-star rating in Virginia Tech's safety evaluation and is suitable for use with e-bikes. It also complies with the American nta8776 standard. Sizes are available in XS-S, M-L, and XL-XXL.

"S" is for head circumferences of 53 to 56 cm, and the head circumference size is the same. "ML" is for 57 to 59 cm, and "XL" is for 60 to 63 cm. I wear the largest size and feel no discomfort at all. Although this helmet is not an Asian fit, recent Troy Lee helmets have become more suitable for Asian head shapes.
For me, a GIRO Asian fit in size L is perfect, but a non-Asian fit L feels a bit tight. Therefore, I think this size range is a welcome feature for mountain biking, where Asian fit options are limited.

When riding on trails, you'll generally wear glasses or eyewear. Here's what it looks like with sunglasses. And here's what it looks like with goggles. There's a groove here to secure the goggles, and by threading the strap through it, they're less likely to shift. Many modern helmets allow goggles to be worn on the forehead, but that seems difficult with this helmet. It might be more suitable for those who use sunglasses.

Next, let's talk about the fins on the top of the helmet, a characteristic feature of Troy Lee helmets. These fins are said to reduce your time by 0.1 seconds. They were present on previous models (like the A3), but in this model, they are incorporated as part of the design. The design looks like this. Also, the price is 14,740 yen including tax, which is relatively affordable, making it a cost-effective model. It's highly recommended for those new to mountain biking or those looking to upgrade their gear.

The Flowline comes in five color options in Japan.
This white is not a pure white; it has a slight pearl finish. The pearl gives it a stylish look. Other options include black, white, and gray, which are easy to match with various outfits. There's also a calm forest green with a stylish metallic texture. And finally, there's a navy color called Mirage Blue, which is pearlescent and sparkling, making it stylish.

I measured the weight, and the L size was 438g.
It's neither particularly light nor heavy.

I hope this serves as a helpful reference for anyone looking for a helmet.
That concludes today's introduction to the Troy Lee Flowline helmet.
