Here's my requirements as I know them today:
Waterproof & breathable (Gortex)
High end armour
Excellent front to back venting
Easy zip on/off
Great warranty (even in Canada)
Basically the one suit you would take to the end of the earth (Tuk?) and back.
I am known to want to strip down in a hurry so intuitive on/off system is a must. I also get hot quickly if the bike isn't moving, so the suit must have some quick off bike adjustment (can a one piece do that?).
Keep em coming.
I have read through the all the posts so far. The range of opinions points to a common set of multiple goals.
Armored body protection
Defend against cold
Defend against heat
Easy On/ Off
Not a lot of concern about cost and no one has mentioned the bulk, weight or flexibility. One person did mention perceived image. The choices, for most of us, needs to rely on the collective historical experience. Personally, my search for the motorcycle clothing grail began in the late "60s. Most of the best gear was spawned in England in the form of Belstaff waxed jackets and pants. There was a ritual that a couple times a years you would heat up some wax and reapply it with a paint brush. A major improvement back then was the development of a wax that didn't stink. I can clearly recall pulling into a store at sundown to buy a newspaper to stuff inside your sleeves, chest and the front of pant legs.
And yes, we had to start the bikes with our leg, so get off my lawn.
Fast forward: My solution for the needs we have is not a "onesie" suit. I think modular works better. I wear body armor. I have a windproof / water proof thin light upper shell. I have an electric vest and electric chaps. And I use modified
high-wasted sailing rain paints. The modification on the pants: I had a local seamstress install waste to cuff velcro to the outside
of the legs behind a flap. Just think of male stripper pants. That totally eliminates the need for the next "new and improved" crotch zipper. And upper shell, pants, chaps and vest rollup into small tail bag on my sports bike or two grab-rail bags on my Vee.
That what works for me and covers all of bases on my ball field. The mega extremes are always going to uncomfortable, short of switching to a pickup. [/End, my 2 cents\]
