Lightweight, comfortable, good ventilation, easy magnet type clip. Got it at in a sale, so good value too.

For my head at least the helmet is comfy. I’ll occasionally, like every maybe 3rd ride, get a little hot spot from one of the bumpers, but all I have to do is just reach up and bump the helmet a little bit and it goes away. This helmet vents so well though that it doesn’t bother me one bit. I’ve been wearing helmets for years from Troy Lee, and Fox that don’t vent one molecule of hot air off my head and to me that’s brutally uncomfortable. The Altec reminds me of good venting Giro helmets before MIPS liners restricted airflow over your noggin. I got the fidlock version and it’s ok, I never had any problems with plain old buckles so that’s a wash, but something else I do like is the visor, it’s just my personal preference but it’s just the right length and width to ... MoreFor my head at least the helmet is comfy.

The Fox visor didn’t do anything and the Troy Lee visor was too long and blocked my vision, especially going downhill. I’m probably going to buy another helmet and store it in a dark room in case 100% stops making it. Again, it’s a personal preference thing but I really love how well this helmet vents. Ps. My head is 57.5cm, I bought a S/M and it fits great

Very comfortable, fits glasses perfect, saved in in a big crash & so I bought another
Comfortable helmet with plenty of ventilation. Would recommend to others……
The helmet is excellent. It’s my second one after a stack. The magnetic catch is the best in class and the helmet is really comfortable for my head shape
Helmet arrived NIB and in great condition. For the helmet, I already own this helmet in another color and love it. This models been discontinued so I wanted another before they become hard to find. Ive loved the Altec for years. Looks great and most importantly for me is it vents and removes heat better than any modern helmet Ive tried (Fox SF, TLD A2, others). Ive read others find this helmet uncomfortable but that hasnt been the case for me. Very comfy for me.
Perfect quality and service
Great helmet, very comfortable and chin straps are great compared to my Troy lee!
Great helmet, fits well - doesn’t look like a bucket! Safety features are good, comfortable and I really like the magnetic clip.
