I've got the complete winter outfit and if i was you i would not take any changes when saving a few $'s due to reasons you explained yourself.

The thing is with Assos that nearly every item runs rather tight along your body and the best thing to do is go to a dealer that has a large inventory and try several sizes.

I've had the Uma LL wintertight and when i wanted the the male's Airtight LL i was adviced to go a size smaller simply because it was made for males and it turned to be very true.

Allthough i truely understand your motivation this overseas choice could end up with a 'penny wise pound foulish' experience.

Good luck in your choices and 'have a good ride'.
