The "Under Armour" shirt is the ideal underwear for the transitional period. I've been using it for the bike path to work when the mesh shirt not sufficiently protect the underwear from the cold. Even if you "plastic" wears almost 100% on the body, the sweat is excellently discharged from the skin. Otherwise, the shirt is really like a second skin. You can see as well as any fat rolls, inasmuch you wear it alone. Furthermore, muscle support is promised by compression through the narrow concerns. Those familiar with the fitness or weight training area, knows quite high material stresses are necessary for a significant support by compression, which definitely does not give this shirt. That would be bad, because then you would not have the freedom of movement Necessary. Who ever a real "Powerlift Shirt" wore, knows what I mean. Finally, one thing that is not so much like that. In a long-sleeved "Under Armour" I would have liked a stand-up collar for even better heat preservation of the sensitive neck area instead of a normal collar. From the length of her (I am almost 2m tall) but it is sufficient to clearly in the gluteal region, so that even when leaning forward (bicycle) the kidney area is fully protected. Conclusion: Perfect Shirt, unfortunately without collar.
