I stumbled onto PatchPanel from Instagram. I am glad I clicked the link to check em out.
I ordered a 1"×1" Wolf Grey/Red Reflective "Cat's Eye" patch for my favorite cap, the patch is PERFECT! It's the right shade of grey to match my hat, and it's just enough red to see without being gawky or too obvious. The "glow in the dark" edge around the red cross accents really cool, but doesn't get a ton of glow (not a criticism, just my observation).
The velcro on the patch is really good too. I liked the laser cut patch style so much, I've already ordered several more patches.
