Hey Bozeman.. glad to have you on board!
The inner wear needs to be sized accurately to perform properly. If the fit is snug at first it will definitely open up for a more relaxed fit over the first 7-10 days of daily use.
If you are sleeping with it right away make sure you have only the inner wear on and not the sleeves layered on top specially with the snug fit when new.
Stay alert to your body response and take a break for a few hours or overnight if any irritation and/or redness begin to occur. The principal being the sooner you rest the sooner you can resume wearing again.
Keep us posted on your progress as you move thru the learning curve.
Cheers!
