What size do ya kneed to get a leaf suit
They base their leafy suit sizes off waist size. So Large is 28"-34", X-Large is 34"-38", and XXL is 38"-44". I'm typically a 36" so I've got the XL and it fits great. Elastic waistband and pulls on over multiple layers in late season. My buddy that wore my suit is bigger than me, maybe 40", and that suit fit him fine. I'd say order true to size and if you're on one of the in betweens--say 34" or 38"--size up so you can layer under them. The one I got, the Premium is a solid suit and not breathable. The Guide Series is breathable. Personally I didn't need it breathable for my purposes but that's a consideration. For $60-$70 you really can't beat those full suits.
