The Vert™ Vest features extended waterproof coverage over the hips and thighs and recycled, lofted insulation that packs exceptional warmth. Leg loops keep the jacket in place when the winds kick up, and the leash portal allows the Vert™ to be worn over a harness. See website for sizing details. Used like new! Worn daily for two weeks on a winter trip. It worked out great, pup just outgrew it.
