I'm a pretty average build guy, 5'11" and about 180, but my shirts always seem to come untucked after just a few swings. I usually wear a large, and I've tried wearing XL's but ended up with the same problem and they are just too big anyway. Is this something everyone just has to deal with, or does somebody make golf shirts that are a little longer?

I have a few Adidas Golf polos that are short and are close to not being long enough to be tucked in. You may just have a longer torso.

I have a very long torso on top of being 6'4". I buy xlt polos which are specifically built for taller people. Try finding golf shirts at big and tall stores that come in tall sizes which should be long enough to tuck in.

I have had that problem before too. I recently bought a couple Under Armour shirts which seem to be a good bit longer and stay tucked in. Hope this helps.

Nike and TW shirts are very long.

I don't even to attempt to tuck in the front of my Adidas shirts.

+1 on the Under Armour shirts.

You'll need more fitted shirts. In regular adidas shirts, they're too short if I get them my correct size for shoulders/stomach. Try the ClimaCool Motion or Formotion. They are more fitted.

that's one of many reasons i don't by cotton shirts anymore... i find that most shrink vertically and i end up having the same problem... on top of them fading faster... not washing as well... etc

Try shopping in the men's section.
