Just for reference, I checked the
Tackla Air 9000 sizing chart at HM (where I bought them). I swear it was different back then but here's what it says:
46 29" - 30" 74 - 77 X-Small
48 31" - 32" 78 - 81 Small
50 32" - 34" 81 - 86 Medium
52 34" - 36" 86 - 91 Large
54 36" - 38" 91 - 96 X-Large
56 38" - 40" 96 - 101 XX-Large
58 44" - 46" N/A XXX-Large
60 48" - 50" N/A XXXX-Large
Looking at this chart, and knowing that the sizing runs big, I would have gone with the 50 based on my metrics: 5.11 - 175 lb - 33" Waist. Not sure what I was thinking...
I ended up buying the 52s and in order to keep the pants high on my hips I have to crank the buckle and draws all the way in. If I were to do it again, I would drop down one size and get the 50s.
I'm guessing that the 48s will be on the snug side for you and the 50s will be on the loose side. So how much weight are you planning on gaining
