I ordered these heavyweight after seeing the midweight ones at REI. I purchased the mediums of the midweight from REI and although I loved them, they were a bit too big, so I gave them to my partner. Since I had to get smaller gloves, I though I might as well get thicker ones while I was at it, so I purchased the heavyweight ones here directly from Fox River. I measured my hand and according to the size guide, I should be a small. These gloves were way to tight around the fingers, so much so that they were cutting off my circulation and my fingers got puffy. At the same time they were too tight in the fingers, they were too loose in the palm and around the wrist. I much preferred the fit and style of the midweight gloves. The cuff around the wrist is much nicer on the midweight ones. Also comparing both side to side, these 'heavyweight' ones don't seem thicker than the midweight ones, so I will be returning and ordering the smalls in midweight.
