I see Johnnie-O, Peter Millar (have had UH for a long time), Tommy Bahama and Onward Reserve. I never heard of Onward Reserve before but their stuff has similar retail price as those others.
Additionally, both Antigua and Cutter and Buck have UH licenses and have stuff for sale online that is basically factory direct embroidered to order (so to speak).
Also can get some high end watches with UH if you’re interested.
Here’s links to my thread in basketball of UH stuff. Some items are not available anymore and some might not be available from the vendor I posted but I might be able to find it elsewhere.
I will add a link to the one in football in a bit.
