I wear these when we walk our dogs in the mornings and they are just perfect.  I'm able to hold the leash securely, get the poop bags out of my pocket, open them and then tie the knot with no problems at all.  They are nice and warm too.  I do have to say I live in California and about the coldest it gets when I wear them is in the 40 degree range, so they might not be warm enough if you have lower temperatures than that.  The lining inside is pretty thin.  But, if you are looking for a nice lightweight glove, you can't go wrong with these.
