Inline with shortsleeve version, great quality and fit
Overall, I recommend this piece of kit. It would be a nice addition to any collection. I, for one, am glad to have it even though I did not really need it as my cycling wardrobe is already tightly curated. However, I was intrigued by the claim that, depending on the base layer, it could satisfy any ride between 40-80 degrees. And while I have not tested it at the low end of 40, I do believe the claim is true. I tested four different base layers (a Giordana sleeveless, an Assos Spring/Fall short sleeve, a Rapha ProTeam lightweight short sleeve, an Assos summer long sleeve) and I am sure my Assos long sleeve Spring/Fall base layer would work with this jersey for a 40 degree ride. The main thing is to dial it in. Originally, I thought I would provide a review of each base layer tested under different riding conditions, but I realize that I run a bit cold and my preference is to dress up (I would rather be too warm than too cold) and that what works for me won’t necessarily work for everyone. Body temperature and comfort may just be as specific as a finger print. In any case, here are a few considerations: The jersey does not wick away sweat well and therefore acts like a sort of air-conditioner. Basically, without a base layer to remove sweat away from your skin, the jersey lets in air without letting out moister and the result is a cooling effect. This is a good thing and a bad thing, depending. On a hot day, it makes for a nice warm breeze if you can keep your speed up. In fact, this quality is a sort of motivator as you got to keep moving to keep cool. One thing is for sure, I would think twice about using the jersey, with or without a base layer, on a 80 degree day where I would be slogging up some exposed mountain for any length of time. On cooler days or even warm days with that Bay Area wind, the right base layer is essential. If fact, one day I went out in the Rapha Proteam lightweight short sleeve base layer and was fine until I hit Samual P. Taylor. The temperature drops there as it always does and there was a bit of a headwind. For that little stretch it felt like my arms were colder than if they had been bare (my core was fine though). I was glad to reach the coast and even happier to be heading up Bofax. The only other consideration is that you got to be careful not to dress up - you don’t want to be in the middle of a ride with the temperature increasing and wishing you could shed a layer with your only options being to strip your jersey or your base layer. Got to check your variable conditions before you suit up. This is not to say that the jersey does not work under viable conditions: I did a ride up to Tam (Assos Summer long sleeve jersey) on one of those days when heading out of the city where I live was in the mid-50s, then heavy with fog and wet all the way up Panoramic until past Pantoll the sun is out and it is 82 degrees heading up to East Peak - I was fine and happy on the descents). In short, my recommendation: Buy it and then dial it.
