In my search for lightweight long sleeve summer jerseys for sun protection I found Pactimo. Always been shy about changing brands as Im already familiar with the fit of brands like Endura, Castelli, and Giordana (which all make quality products) I decided to try the Ascent Aero and the Ascent standard fit both in XL. I'm 59 yo, quite fit. 6' 185 lbs. I found the Aero fit pretty good. Not super tight and not too loose. The standard was a bit roomy so I've sent it for a Aero Large. The XL fits pretty good but I'm curious to see how the large aero compares. just to nail it down on size. I'm taking the time expir ent between XL and L because I've found it's a quality made product with nice material so I'll likely add them to my list of go to's particularly if I catch something on sell that I need. My only gripe is shipping and handling. After I ordered it took them three days just to process and hand off to USPS...yea, that's right, usps ground!!! They probably paid 6-8 bucks for ground and they could've paid three more for priority. As far as Im concerned that's a sad way to further Buisness and compete with the Amazons of the world. There days just to process then snail mail. That'll definitely be a consigning forward. BTW from the time I pressed "pay now" till i received was 8 days, Im in North Carolina.
