These shirts are made with special material that uses FIR, infrared emitting fabric. This technology helps promote blood circulation and increased oxygen levels, boosting recovery from training and high impact activity. It’s also great for sporting, long walks, or for senior dogs. These shirts are very comfortable and flexible, and they have a lot of coverage, so they would also work well for chilly morning walks and regular usage in cool weather. The muscle warming function makes this outfit a good alternative to Hurtta’s Body Warmer, featured on our Winter Coats page. The Recovery outfit is available in shirt or overall format, in sizes 10 – 26.
