Warm and effective across a range of temperatures. Its all about the layering

Got the Flanders long sleeve, not because I live in Flanders, but because it is perfect for the conditions here. I use this with a Perfetto down to 4 degrees and not too hot up to 10 or even 12 degrees with the Pefetto side vents open. At a push I'd use it down to O with the Perfetto if I was putting in effort and generating heat. I use it with the Alpha RoS jacket when really cold, under 4 degrees and the weather looking like it might turn worse. I've used it sub zero with the RoS jacket and no doubt it would go much lower with it. I have not yet found it too warm and it transports moisture away well. Perhaps if you were riding particularly hard, it may feel a little warm, but for Zone 2 base rides, it is perfect across a wide temperature range and feels surprising comfortable. It is an extremely flexible base layer for me.
Conferrable & Warm

Honestly, this is warmer than I expected. For cycling I'm not wearing this too often (it doesn't get cold enough here, the PERFETTO alone is enough). That being said, I am loving this for my early morning runs, and the few days when it's cold enough. It's form fitting, and the vents for the sweat do help a lot. Definitely my favorite warm base layer.
