HI Everyone,
We tried to keep zippers to a minimum as they don't stretch, lose heat, and add cost to the item. I know it's not as convenient for some without the back zipper but we really wanted to achieve maximum insulation and flex.
You definitely have to don the suit in much the same manner as the Fusion. It does get easier after a few times, trust me. Also in the ankles I know that it does feel like the material is bunching, but if you have pulled the inner core up correctly it's not bunching. What we did is stop the inner liner in this position because if we add bulk to the ankles it makes it difficult to don the feet of your Fusion. We are working on a really sweet Thermal Fusion sock right now!
Cheers,
Justin
