The personal note and card was written with great care and they even included a bit of Christmas chocolate.  I would give your customer care a 10/10, which is why it pains me to give your product a 2/5.

When you work at night in the winter in the coldest climates that Wisconsin, North Dakota, & Upper Peninsula has to offer, or if you work in a cold refrigerator shed where it gets to 20 below, you find out real quick which mitts keeps your hands warm, and which don't.

Riparo Waterproof mitts work ok, Klondike Chopper mitts work well, but all the best mitts that really kept my hands warm all had one thing in common.  They were waterproof & airtight.  I don't know why most manufactures advertise evaporating moisture away from your hand.  This is actually bad.  You need to water proof them to keep moisture from getting in or out.  When you sweat, the hottest water particles evaporate taking warmth away from your body making you colder.  With waterproof mitts your hands will get a little moist from sweat but they WILL stay warm.  A little bit of uncomfort is better than frozen hands.  This is from some one who worked for 4 years in cold climates in relative comfort while others who had expensive mitts had their hands freeze.  Best gloves were thick cotton with a thick coat of pvc.

In my experience I just don't believe there is a balance between insulation and breathability in really cold weather.  I do however want to switch to all natural materials as avoiding chemicals is generally good for your health.  I may try to order another (smaller) pair and layer both inside of an all natural leather liner.  This should make them thicker, more insulated, & stop the cold wind from blowing through the porous fabric.

I do like the fact that that your mitts are all natural and you seem to put a lot of effort into caring for both your product and customers.  For that I am grateful.  I am open to criticism so please leave any comments below.  Thanks.
