These gloves have some good features such as waterproof, breathable, good build quality etc. But they aren't much warmer than my Sigma lt gloves. The 200 grams of primaloft insulation just isn't enough.
These gloves only weigh 8 ounces and I think as far as gloves are concerned, the heavier they are, the warmer they are going to be(some exceptions).
I exchanged them for some Marmot ultimate guide gloves (which weigh 13 ounces) and they are significantly warmer and cost $20 less.
