Breathable fleece, vest silhouette. All the warmth, and maximum movement.
Details
The one that keeps them warm without slowing them down.
Cool morning, brisk evening, the kind of walk where the air has a proper bite to it - the Climate Changer Fleece Vest is the layer for dogs who need warmth without anything getting in the way. The vest silhouette is the key: no sleeves means nothing to restrict the shoulders, nothing to chafe, nothing to fight against. Just 100% recycled polyester fleece, warm without bulk, with extended coverage over the hips and thighs where it counts.
Side-release buckles make it quick on and quick off, and a leash portal on the back means it works over most harnesses without any fiddling. If the wind picks up, the optional stretch leg loops keep everything in place and stop the drafts getting in.
Wear it alone on crisp mornings, or layer it under a shell when the weather means business. Either way, it stays out of their way and does its job.
