Honestly, I have kept the whole compression issue for frills. Clear: warm in winter, cool in summer. Based on the reviews and comments, I was curious. In addition, the price of compression underwear is hot. If s is not fit at least I have more sports underwear ... so what. But surprise: I made a bike ride when the first rays of sunshine finally fought this year by the uniform gray. It was still very cold at the start. Onion look was announced. I have very good arm and leg warmers - but often has the slipstream but pulled to his chest and the thighs. Not this time. Was very pleasant. Gradually I was able to strip off arms and even leg warmers, the fleece disappeared into the backpack. The compression underwear is not allowed by the sometimes heated (and cold) gusts. When it was hot did not feel that the shorts and the shirt as overwhelming. In addition, I must say that I really had a very dry sense of the body - and I drive very jagged.
Conclusion: cool part and cooler price .... have bought equal a second set.
