Here is my experience: I am 5'6" 160+ lbs, 34 waist, 30 inseam - in other words, just a bit fatter than you...
I fit fairly well into my collection of gear (if interested, I can look up the sizes):
- Aerostich 2-piece suit,
- BMW summer 1-piece suit,
- BMW 2-piece 3-phase suit,
- 2-piece leather suit from Talexx (via eBay)
- one of Hein-Gericke's watherproof leather/textile sets (after a lot of trying)
I cannot fit for sure into:
- Olympia pants (too long)
- most Hein-Gericke pants (too long)
- Fieldsheer pants (am just returning their 4-season mesh, really nice & quality, but way to tall).
Generally, I have no problems with jackets; I typically fit into medium sizes.
Hope that helps.
By the way, I just realized that my closet is too full!
