Comfortable, well sorted helmet!
I just received my TLD A3 helmet this morning.
Shipping from Fortnine was excellent as usual.
The helmet is beyond my expectations, it fits perfectly and has all the features I wanted. I was surprised that it came with an extra liner and a helmet bag which is great for storage
In my garage over the winter. Overall very happy with my purchase.

Great Helmet
TLD never disappointed me. Design, material quality and comfort are present on their products.
Only downside is that the adjustable strap is only for the length and not for the double straps coming from back and front (like most helmets nowadays), which helps to adjust it up and down.
Helmets fitting are different and fits better in different head shapes.

Get an A3!
Great helmet! Looks cool, fits perfectly, keeps sweat out of my eyes. Favorite one I've ever had.

Solid Pick for Trail Duty
Fits well, stays in place, Fidlock is hard to live without. Light, good ventilation, comfortable. The band over the brow does a good job of keeping sweat out of your eyes, until it doesn't - then it tends to run. Otherwise, good quality, no complaints.

Great helmet but clasp/buckle is weird
This is my second Troy Lee MIPS helmet. My last one was only replaced because the straps got twisted and became uncomfortable and dangerous to use.
This new one? Excellent. The strap configuration is different and the straps basically are unable to be twisted.
The only thing I don't like is the magnet/slot clasp. Sliding it sideways to open isn't as intuitive as the buckle, but I'll get used to it.
Another win for style with protection!
