I'm happy with these gloves. I tried some Pearl Izumi AMfib Lobster gloves size Medium and they were too small (but also warm). These seem to be rated for lower temperature, so after the misfire on the IP I went with these. First ride was 38F and my hands were basically overheating. For me thats a win as I'm looking for comfort down to 20F and below and I'm certain these will deliver.
I followed the fit guide (go here) and it determined I need a Medium and that was indeed the case as they fit perfect.
