Congrats on being a *good* boy and receiving your just rewards from Santa. The CyclePort gear is pretty stiff, but does loosen up with wear. Definitely take it to a laundromat and follow Wayne's washing instructions, that will help a bit.
As far as getting into the pants...I unzip everything as far as it will go. Boots on, left all the way up and right side completely open. Step through the left and swing the right into position. After a few tries it does get easier. The velcro is a PITA...
Enjoy your new gear!
