Keeps the digits warm

  • Familiarity: I've put it through the wringer

Bought these for long sits in my treestand or behind binoculars while elk and deer hunting. They do a good job of keeping fingers warm, are easy to pull on and off with the big pull tabs, and are nice and soft inside. Add a hand warmer inside if you're really prone to cold fingers. I've used these in temps down to 25 degrees without issue.

Very warm

Very warm mittens, obviously not much dexterity given that it is a mitten. Best part about them is how soft they are.

Thank you for the review, Salman!

Sized Small

  • Familiarity: I've used it once or twice and have initial impressions

Some initial impressions about this mitten. It is sized very small. The tag says unisex sizing, but I would call it women's sizing. I usually buy Xlarge mittens because I like them to fit very loosely, but size XL in this mitten is fairly snug. So it's at least 1 size smaller than normal. Also, they are not very puffy at all (see image). It seems that there is not much down insulation relative to synthetic, and so they are less compressible than I was expecting. Nevertheless, they seem well constructed and feel like they'll be very warm. Another plus is that they fit inside the Altimitt shell.
