What size would be good for a 30 in. Waist

Probably a small. They run big and are generous. I enjoy mine, very comfortable.

Small fits 30" waist. Had to remove part of velcro that overlapped and chaffed clothing. Good product, well made. Wouldn't work well with 1911 or other heavy pistols. Perfect for small and med frame revolver or auto.

my waist measures 36 and the XL was too Large for me so I sent it back. But have been thinking of getting Large. good luck let me know what your decide.

My son wears a 30 inch waist in jeans, and they fit him perfectly, but I think with them having an elastic waist, you would be fine.

I have a 33" waist and I bought the medium size. It's perfect for me but for someone with a much larger waist it would be hard to use. I'd guess for a waist of maybe 40" or less the medium would be good and for bigger, the large would be good.

I'm a waist 32" about 160lbs, and a medium just fits me. Unless your under 150lbs go Large. Good luck.

Not sure. I wear a Medium and I have a 32 inch waist. I could probably wear a small but it would probably be tighter than I want. I would say wear small up to 31-21 inches.

my husband prefers the Medium and has a 32" waist. He could wear the small, but likes them not too tight.

The first answer is helpful, HOWEVER, I am a 31" waist. The small fits too snug to wear comfortably, the medium was closer to the 35" mark and fit very loosely. Sizing is accurate, but do not order smaller if you are borderline.

I'm about that size on the top and 30-inch waist and I wear a medium. If you like it to fit tightly, purchase a small. If you're going to layer it with a shirt underneath, a medium.

I've got a 34 waist and there is still room to sinch it tighter. I would say it would definitely fit a 31 waist.

You would need a regular or medium. I have a 34-36 waist and the large fits perfect

I'm 6-1, about 203 and have a 34 inch waist. I got a large which fits perfectly. I would say a medium for you if you have a 31 inch waist.

I imagine large. I have a 42 chest and 30" waist. Bought large but medium would have been better. Not huge but a bit too big for me. Good luck

I have a 30" waist and the size Small fits perfectly. It would probably fit a 28" waist since it is quite stretchy but I obviously cant say for sure. I think my inseam is 32". I wasn't concerned about an exact length because they are a base layer. And, I can't speak for larger sizes.

My waist is larger, I bought large when I should gotten XL. Sounds like you could use Medium.

I would go for the medium. I am a 35" hip and a 27" waist and I took the small, they were quite comfortable.

I have a 34 waist and the Large are snug for me. Large might work for 36 if looking for a very tight fit, but for a more comfortable fit I would look to the XL (especially for someone taller than 5'10" or with large quadreceps).
