I don't have any comment on how warm they are, but the build quality is definitely not up to par for the price. After a few uses the securing strap has split into two pieces. While it doesn't effect the functionality of the strap it's very disappointing to see them fall apart like that. It makes me nervous that they've worn that much after only 3 or so uses. How will they wear after a bit more time has passed? The rest of the glove is decent though, the palm offers some decent protection from the leather but it doesn't bunch up.
