I'm sold on RS Taichi!
This jacket would be a great deal at full price $189, but at $119, it's a STEAL! CE level armor in the shoulders, elbows, hard chest protector AND back protector. Mesh flows air VERY well. I wear a Euro 48, and the Japan Large is a perfect match. The fit of this jacket isn't as racer snug as my Dainese leather, but it's not supposed to be a race jacket. Only small negative is that the back protector gets very warm. Not really even a negative since virtually no jacket at this price point includes a back protector. I replaced it with a Astars KR-Celli (M) and it's light, airy, and a perfect fit for this jacket!
(BTW, it's ta-EE-chee NOT tie-CHI)
