The Ruffwear Sun Shower is a weatherproof rain jacket built for the trail. The waterproof fabric helps extend adventures into wet weather by keeping dogs comfortable. The non-insulated design allows for use in warm climates and can be worn over insulating layers for cold climates. Full coverage minimizes the wet, muddy dog cleanup. The Sun Shower is available in 6 sizes. Select the correct size based on your dog's girth (measurement around the widest part of the rib cage).
