Feature Overview Loved Dogs. Approved by Parents. ✓ Choke Free - patented X-frame and Deep V Neck Design so there's nothing pulling against your little dog's neck. ✓ Escape Free - we've repositioned the two side strap sliders. This allows the harness to contract even more when your pup is trying to slip out of the harness. ✓ Reinforced Internal Nylon Strap - there's a hidden internal nylon strap that's sandwiched between the inner and outer layer of the harness. It's a fully body strap that wraps around your dog's entire chest and adds an extra layer of protection. ✓ Name Tag Attachment - there's a hidden side pouch that securely holds the name tag to ensure quick identification if you dog ever gets lost. ✓ Metal Hardwares - even though the POM plastic d-rings were already secure, people were still having doubt whether it was strong enough. So, we changed the leash attachment d-rings and the strap adjuster hex rings from POM plastic to metal. ✓ Reflective Linings - we added reflective lining to increase visibility when walking at night. ✓ Scratch Resistant Outer Layer - keeps the harness away from fraying when your dog scratches it with their paws. ✓ Moisture Wicking Chest Plate - dries quickly against wet elements on those walks. ✓ Quick Release Buckle - easier on your fingers and requires less effort to open. Why Escape Free? How many times has your dog tried to escape by backing out of its harness? The result of "that one time my dog escaped from its harness" can be a scary one. If you're fortunate, you might be able to catch your dog before something happens. But as dog parents ourselves, we are all certain that none of us want to ever take that chance.The Gooby Escape Free Series were created for exactly that. The Patented Escape Free design contracts the harness when dogs try to back out, which tightens the space around their body and hugs them tightly so the harness will not slip off.
