What size would be 34-38 short? Is it medium short??

I normally wear 35 or 36 short. These pants are usually worn over your regular jeans so I bought large. They really are a bit to big and long so probably the medium short would be better. Depends on whether you want some extra roominess for coverage, ventilation and flexibility or a less bulky fit.

What size would be best for 38x30?

34x32, what size is recommended ?

Good Morning,Thank you for contacting Propper International. You can find the sizing chart on our website at: https://www.propper.com/propperr-wildland-pant.html. 34 is the end of the small size and beginning of the medium size. Small may be a bit snug, where medium may be a little roomy. You will want the regular length.Thank you,Casey HowardPropper InternationaleCommerce Customer Service
