I've purchased about a dozen tactical caps and many flag parches from Gadsden & Culpeper. I have received excellent service including the prompt replacement of one flag patch which arrived with a frayed edge stitching. Condor tactical caps fit, but I'm at the upper limit for size. The 5.11 Tactical Cap is a little bit bigger and fits me better. The quality is great and I'm very happy I found a color I prefer on sale.
G&C's patches are very high quality and both 3.5" x 2" patches for 5.11s and 3" x 2" for the Condors fit perfectly.
I wish Gadsden & Culpepper carried larger tactical caps. Something sized like the Flexfit 6766 in XL-XXL. Not all of us are midgets and one-size does not fit all.
