Your closest option will be the pro shop at Mad Cow paintball (www.madcowpaintball.com) but i'm not sure how much clothing they carry in stock. You could also try giving them a call to see what they carry.
ICU in Des Moines is the closest pro shop now DSS is closed. I also know Warped Sportz is back out by Kearny but I don't know if they have a pro shop or just an online store. Btw Jake we need DSS back. I hate buying my stuff online.
