Very comfortable. Great fit.
Great fit, very comfortable, wear all day, 40-50 degree weather with sweater or heat tech. Weight was just right not bulky or heavy. Best of all its machine washable unlike many of these coats.

Great product and value for money
Size: XX-Large, Color: Army Green
Value for money is great. Coat really absorbs cold. Just need to test if it water resistant. Laundry / cleaning of the product is also easy with instruction on the label.
