#6180 is a good model to start with. This particular one is denim and the caps are low-profile, but with a hard-buckrum crown, which keeps the front from squashing down. FlexFit caps don't have a buckle or strap that would emboss your forehead if you wore it backwards under a protest helmet. The FlexFit multi-national patents are for the headband that's a piece of wide elastic, 4 x stronger than you'd find in a pair of Hanes® marble-bagger underwear.
If your still reading, I would suggest that you make the S&S logo smaller, and have the logo embroidered into the crown. For instance, use a dark Navy thread for a small logo on this denim cap. The navy would show up, but set against the denim would not make a person a walking billboard.
You can turn the S&S label into a m/c sought after statement that the other populace would also wear, much like Rusty Surfboards did with their "R". http://www.rusty.com/
There styles to choose from, all with the elastic headband. Camo would be good model. # 6277 is supreme though. Try embroidering the logo in a near-to-same color thread as the background piece. A charcoal or gray S&S on a black cap. Red thread on a gray cap.
I think some good decisions in apparel like slash-cut wool watch caps that protect your ears under a protest helmet, and some other direct-comfort clothing items would "bridge" S&S with some extra income through the winter and beyond.
Here's a FlexFit® from Big Bear choppers on a Boulder tombstone. No buckle. Rear logo availability. Good choice. Click the link on the bottom post, (past my fans comments). - Takes you right to #6277 (low-profile) not to be mistaken with the 6277V (wool) which is a different animal completely, mid-height cap and butt-ugly (unless your selling Corn-Dogs-On-A-Stick at the county fair, in which case it's for you.)
This particular model # 6277 is a blend of 63% polyester, 34% cotton, and 3% Spandex. Crown's fused buckrum.
