I have been wearing Pactimo cycling kit almost exclusively for approximately five years. Pactimo apparel has been the most comfortable compared to other apparel I have worn. Most notably, I struggle in the summer heat. Pactimo apparel, especially the FlyteSuit, wicks away sweat and manages to keep me as cool as possible. I've been able to race on days where I was unable to in the past. I recently purchased sun sleeves. I was skeptical they would keep me even cooler than bare skin, but they were like having an evaporative air conditioner on my arms. That prompted me to try the Summit summer base layer. I haven't had the chance to try the base layer yet. I am waiting for the right time to try it out. All in all, I am a Pactimo fanboy. The apparel has been outstanding. Most importantly, the apparel, especially the cycling kit, is always improving. Each iteration is better than the previous one. I always look forward to "new kit day" to see the innovations. If you're on the fence, just dive in head first into Pactimo. You won't regret it.
