Ordered an ascent aero jersey and pairs of the summit stratos (XL) and summit raptor (XXL) in long to try something new (current kit is Assos mille series bought on super sale) and I'm super happy so far. I'm 6'7", 245 so absolutely not a typical cyclist build and I often have trouble with sizing because I'm very much built like a potato on toothpicks: bibs are often too short and jerseys rarely make it around my barrel chest. The Stratos in XL long are perfect, and I'll exchange the Raptors for an XL long, too. The jersey is a 3x and it's just about perfect. It's not skin tight aero, but I'm not built for that and the sleeves are almost perfect. When I try club fits they tend to look like tank tops since the sleeves are way too short. Hopefully the chamois keeps up the good work on an upcoming century but so far so good.
