I've used these for about 2 years now. They have many different uses and work great for them all. They do well in a mild winter climate (around freezing) by themselves. They keep me comfortable if I'm just out and about walking around, no need for a heavy winter glove. When it does drop even colder, I like using a tight fitting light winter glove (gives great finger dexterity) with these on underneath. Finally, I use a pair of these almost daily just as driving gloves (great for sweaty palms or just a hot wheel/shifter). Every Terramar product I've owned has been equally wonderful, and I recommend them fully as a general winter/thermal company.
