Now have 4 compression shirt's sub. Dual 2 times, 2 times cold. This Long Sleeve Cold I use now when it gets cold under my softshell cycling jacket. Until about 10-12 degrees is sufficient that. The Cold I like better than the dual. Better fabric and soft. Especially better compression. The long sleeve I took in size M, which has turned out to be correct. Short sleeve all in S. This Short Sleeve Cold I have used in the summer, when it was not quite as warm. But in size S, it is tight well. Since the Cold have more compression as the dual one should take the long sleeve one size larger. Otherwise very difficult to attract. Bin 1.69 m, 64 kg Chest 90-92 cm, waist 86-87 cm. The Long Sleeve Cold in size M fits just fine. Arms right length and well noticeable compression. Below also ideal length. The fabric is brushed inside velvety soft, the outside also pleasantly soft. As a comparison, I had ordered a UA (CG Mock). In size S / M. Arms were too long, too long below also. Is thinner than the Sub. Expensive for well over 30 euros. Returned.
