Replying to Helly Hansen Outerwear Help

So im Buying the Show down Jacket and the Transfer Pant Striped from Helly hansen, but im a little skeptical on the sizes.
Im 5'11 and about 190 pounds so im stuck between large and extra large. I just dont want xl to be too hugggeee, but im scared small might be, well, too small. So can anyone tell me if their stuff runs big? My Siver suit was large and thats kinda feelin snug, but its been washed a billion times because its white.
any input is appreciated.
Thanks
Ben
