The unique benefits of Flecta Hi-Vis Jackets. Petlife Flecta Hi-Vis Dog Jackets are constructed to give maximum visibility day or night. 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. Incorporated between the inner & outer layers of the Flecta Hi-Vis Dog Jacket is a layer of Flectalon thermal insulation. Developed from NASA research into aluminised surfaces, Flectalon can reflect up to 95% of radiated heat by using a revolutionary lightweight insulating material specifically designed for its thermal properties. A Flecta Hi-Vis Dog Jacket is water-resistant, so your pet stays warm & dry, but it is still machine washable at 40C maximum. With its high visibility, thermal insulation, positive clasps & adjustable straps, your Flecta Hi-Vis Dog Jacket is the ideal treat for your dog & you.
