As a long-time owner of a one-piece Aerostich suit, I really appreciate the design's use of a single zipper that runs from the neck to the ankle. Ingress/egress is a snap. It's not clear how this new suit on the market uses zippers. I also have (since last summer) an Olympia one-piece suit that's great for riding in hot weather. The zippers on the legs that run from the waist to the ankles are very much inferior to the Aerostich design. Night and day difference in terms of convenience. This could be a deal breaker for me. I'm looking to replace my old 'stich. But, the older I get, the more I value a design that allows me to dress myself without my butler's help (he rarely rides with us).
