Spidi Laser Pro One Piece Perforated Motorcycle Leather Suit, black-red, Size 48 for Men

Prefacing this by saying this is my first race suit & my primary focus was on protection. Overall, feels like a great suit though. Has the highest ("AAA") protection rating according to EN 17092-2:2017. I'm 165 lbs, 5'7" with an athletic build, and the size 50 fits nearly perfectly (feels a bit tight in the shoulders & thighs, but I expect that with most clothes anyway, and I'm confident it'll stretch out a bit).Walking around it's not the most comfortable, but I doubt most suits are. On the bike, it feels fantastic, with the limbs 'pre-curved' just the right amount. Used this for a track class & even got my knee down for the first time, and the knee pucks held up great.One drawback is that this suit is VERY hot. During my track class it was 90+ degrees ... MorePrefacing this by saying this is my first race suit & my primary focus was on protection. Overall, feels like a great suit though.

Used this for a track class & even got my knee down for the first time, and the knee pucks held up great.One drawback is that this suit is VERY hot. During my track class it was 90+ degrees Fahrenheit, and I had to open the zip on the front to get any meaningful airflow to my torso, and forget about airflow to your legs. That said, basically everyone was getting overheated that day regardless of their gear (including people in textile stuff), so could have just been that day's weather.The only other thing I didn't like was the exclusion of a back protector, which you have to buy separately. I know most jackets do the same, but I was expecting a full race suit to include one. Not a huge issue but I would've liked to have one during my track class, so I'll be buying that as well.TLDR: Excellent suit, fit me like a glove at 165 lbs, 5'7". Not the best airflow but not any worse than most gear that provides this level of protection. Looks great & feels very comfortable on the bike. 5/5 from me.

I'm 5'10 165 and I tried a 52. Unfortunately it was so narrow through the shoulders that I basically couldn't move my arms. There also wasn't quite enough room in the knee area for me to bend my knees comfortably. 4 stars since it seemed well made and fit will be different for different people
