Conscious Small Hot Water Bottle is a compact hot water bottle cover designed to offer gentle warmth on slightly chilly nights and during the changing seasons.

Small enough to fit in the palm of your hand, the hot water bottle can easily be moved around under the covers—to warm cold feet, rest against your stomach, or soothe your shoulders and other areas where you feel the chill.

Because it is not too heavy, it is also comfortable to use as you unwind before sleep.

Rather than providing intense warmth throughout the coldest days of winter, this little hot water bottle is especially suited to those evenings in early spring or before winter when you think, “It feels just a little chilly.”

Its gentle warmth gradually spreads through the body, and before you know it, you may find yourself drifting off to sleep. There is a quiet sense of comfort that comes with its small size.

To help such a compact hot water bottle retain warmth for as long as possible, the outer fabric is made from a cashmere-blend cotton with excellent thermal insulation and moisture-responsive heat-generating properties. The lining is made from a blend of regenerated cellulose and wool designed to return naturally to the earth.The double-layer construction offers the gentle warmth and comfort unique to natural materials.

Currently available in Fog Grey only.
