I've had the gloves for a week now and have preliminary results.
DeerTours:
This is a great glove for fall or spring. Very comfortable, should be bullet proof (Deer and Elk skin). Can't report on water resistance, but they are not advertised as waterproof. Good tactile feel, I can remove wallet, take out credit card, and complete refueling with gloves on. Only thing I didn't like was non-perforation makes them too hot for summer use. It would be nice if they offerred a peforated version. For summer, my favorite is the Olympia Gel Perforated glove. Sizing wise, I'd recommend staying with your normal size. The scale on the website said I needed a small. They came in way too small and I returned for a large, my normal glove size. Customer service at both direct Lee Parks site and Fox Creek Leather was super. No problem with the exchange.
DeerSports PCi:
I ordered these as winter cold weather. They have the magic lining referenced above. So far, so good. Unfortunately (or fortunately!), we haven't had morning temperature below 46 degrees yet. At that temperature, no problem whatsoever, nice and toasty warm. Lining is much thinner than Thinsulate, so tactile feel is much better. Not as good as an unlined glove, but close. I love the long gauntlet and velcro strip right at the wrist, where it should be for safety. Gauntlet will go over anything jacket or coat wise you wear, so good protection from wind. Same comment regarding size as above. Stay with your normal size. These are advertised as also cooling with the liner, but my experience on a warm afternoon ride home was they were too hot for me, went back to the Olympia Gel.
Both gloves are expensive, but appear to warrant that with quality.
