[Thermolite] Thermolite(R) Core technology keeps you warm. In addition to its heat-retaining properties, it is also stretchy and designed to dry faster than conventional products.
[Petitheat Premium] Moisture in the air is absorbed into the fibers, generating heat and preventing your dog's body heat from escaping. Not only does it have better heat-generating and heat-retaining properties than conventional Petitheat, but the fabric is thicker and has a brushed surface for a warm feel. It is also highly stretchable, so it won't restrict your dog's movement.
