Petlife Flectalon Hi-Vis Dog Jackets are constructed to give maximum visibility day or night & keep your dog snug & warm with the layer of Flectalon thermal insulation between the outer & inner layers of the coat which can reflect up to 95% of the heat radiated out from your dog back to him. During daylight, the fluorescent yellow can be seen from considerable distances & during darkness any light will be immediately reflected from the reflective stripes on both sides. These features are hugely beneficial to responsible dog owners & also offer personal safety for the owner/walker. The flectalon Hi-Vis Dog Jacket is water-resistant, so your pet stays warm & dry, but it is still machine washable at 40°C maximum. With its high visibility, thermal insulation, positive clasps & adjustable straps, your flectalon Hi-Vis Dog Jacket is the ideal treat for your dog & you.
