  • Cooling Add-On for Harnesses and Packs

    The Ruffwear Swamp Cooler Core is an add-on to Ruffwear harnesses that cools dogs, adds additional support when lifting and assisting, and further stabilizes packs and harnesses. This three-layer chest panel uses evaporative cooling to efficiently pull heat from the dog’s core during warm temperatures and high intensity activities. To activate, wet the Cooler Core with water and wring out. The Cooler Core easily attaches to Ruffwear harnesses and packs using hook-and-loop sleeves:

    WHAT'S NEW! Updated external air mesh for improved abrasion resistance and improved water absorption.

      - Outer Layer: Reflects heat and facilitates evaporation
      - Middle Layer: Absorbs and holds water for evaporation
      - Inner Layer: Mesh lining keeps dogs dry and comfortable
