Thicker, bulkier gloves may be warmer because they are made with more materials. More material- especially in the fingers- some dexterity is lost. The Punishers balance the spectrum between warmth and dexterity well. They are warm enough for zero degree days climbing (plus, I use them for backcountry skiing) but nimble enough to handle most ropes, bindings, and climbing gear while wearing them. One drawback: with no removable liners they dry a bit slow. (See image this page)

Just got for Xmas, but here's what I notice. I have severely beat-up Cloudveil Ice Flow gloves from the last 3+ years. Everywhere my old gloves are worn through, the BDs have the necessary reinforced padding/stitching. For instance, there is added padding to the top of the pinky where each of my old gloves ripped. Also the leather section between the thumb and forefinger covers a smaller area - which is good since on the old gloves it was too much. Really only needed where you squeeze the tool. No padding on the back of the 1st 2 fingers like Ice Flows - not needed.

They fight slightly tight, but that is part of the dexterity plan. The leather goes over the finger from top-to-bottom, rather than side-to-side, creating a better smooth fingertip experience. When on, my hands literally rest with thumb and forefinger touching tips, perfect for the next screw. I even used the computer mouse fairly well with them on. Perfect for avoiding bulk but staying warm (I expect).

I use these for backcountry and frontcountry splitboarding. they're warm enough most of the time, and too warm every once in a while, so their range is impressive. the nimbleness is the feature i was most looking for with these gloves, so i could transition from uphill to downhill quickly, which they perform quite well at! i find the cuffs too short for my needs much of the time. after a couple years of heavy use, there is some wear on the pittards, but overall, they seem to be holding up well.
