I own both Kincos and WL Mitts. It's hard to say which is better though, kinco has amazing durability but you have to waterproof them a bit in order to make them alright for wet days. The WL mitts I got were a goodie in with a level 1 order. They arent the full leather wraps and are similar in looks (not sure about specs) to the Lifty mitt on WL's website. I use both interchangeably with Kincos for colder 10-5 and below and WL for anything else. Both resist tears very well (from trees, usage, and edge grabbing) but overall I just found the kincos to be beefy and not as freeing as the WL mits hence why I only use them for cold days. If I were buying a new pair of mitts rn, I'd be looking at these guys from WL. (

Plus from the looks of the mitts, they have the little "finger slots" (idk how to explain that but someone gets it) in the mitts that will keep your hands just a little warmer while still maintaining the functionality of a mitten.
