It takes two seconds. Something startles them — a car door, a dog barking — they drop their shoulders, step backwards, and they're standing outside the harness looking at you. If it's happened once you already know the feeling, and you haven't taken them out since.

This is built for exactly that moment. Cats and nervous dogs don't wriggle out of harnesses, they reverse out of them. The anti-escape closure resists going backwards, and the dual adjustment removes the gap they slip through.

  • Anti-escape closure — resists reversing, which is how the escape actually happens.
  • Two-point hold — chest and behind the shoulders, so collapsing one doesn't free the other.
  • Reflective trim — you'll see them in headlights on a winter evening.
  • Breathable mesh — light enough for a cat, cool enough for August.
  • Lead included — already sized to the harness. Nothing else to buy.

Choosing your size

Measure the chest just behind the front legs, snug enough to slide two fingers under the tape. Between two sizes, go up. Four sizes, S to XL, kittens and puppies through to adults.

Questions people ask

My cat has escaped every harness I've bought. Why would this one hold?
Because the others held at one point. A cat can collapse its shoulders until its chest is narrower than its head — one strap slides straight off. This holds at two. Here's the full explanation.

Do I need to buy a lead too?
No. It's in the box and it matches.

How do I get a cat used to it?
Three weeks, not three minutes. Harness on the floor by the food bowl first, then short sessions indoors, then the lead indoors, then somewhere quiet outside. Almost every escape story starts with week three happening on day two.

What if it doesn't fit?
30 days to send it back. We cover return postage if the item is faulty, damaged or wrong; if it's a change of mind or the size isn't right, the return postage is yours.

Sixteen colour and size combinations, including Blue, Black and Pink.

Safety: inspect before each use and stop using it if anything is damaged. It is not a substitute for supervision.

How to measure

Get the size right the first time.

Measure before you order. A snug, level fit is what makes it comfortable.

1. Measure the chest girth

Wrap a soft tape around the widest part of the ribcage, just behind the front legs. This is the most important measurement.

2. Measure the neck

Measure around the base of the neck where a collar would normally sit.

3. Compare to the size chart

Match your measurements to the size chart in the product images. If your dog is between sizes, size up.

Still not sure?

Email us your dog's breed, weight and chest measurement and we'll recommend a size.

Great product and smooth delivery

Something startled Finn, she dropped her shoulders, stepped back and was standing outside her old harness — so I bought the Reflex set. The dual adjustment closed the gap she used to slip through, and I could fit it properly on a narrow-chested dog. The anti-escape closure resists reversing, which is how the escape actually happens — she's tried twice and stayed in it. Very happy with it. Shipping was smooth, with useful tracking updates and no delays.

Very happy with the order

Bought this to leash train a cat, which every normal harness failed at. The reflective trim shows up clearly in headlights on a winter evening. The dual adjustment closed the gap she used to slip through, and I could fit it properly on a narrow-chested dog. Best harness for an escape artist that I've found. Held up better than I expected. The order arrived when expected, securely packed and ready to use.

Something startled Finn, she dropped her shoulders, stepped back and was standing outside her old harness — so I bought the Reflex set. The breathable mesh is light enough for a cat and cool enough for August walks. The lead came with it, already sized to the harness, so there was nothing extra to buy. We're back to daily walks, which I didn't expect. Good quality for what I paid. The order arrived when expected, securely packed and ready to use.

No complaint about the item, terrible delay

Bought this to leash train a cat, which every normal harness failed at. The anti-escape closure resists reversing, which is how the escape actually happens — she's tried twice and stayed in it. The two-point hold across the chest and behind the shoulders means collapsing one point doesn't set her free. The breathable mesh is light enough for a cat and cool enough for August walks. Cats need a few days indoors in it before you go outside. We're back to daily walks, which I didn't expect. No complaints at all. There is nothing wrong with the product. I am giving one star because shipping took far beyond the promised window and the parcel appeared stuck in transit for days without helpful updates.

Product is good, delivery was unacceptable

Something startled Theo, she dropped her shoulders, stepped back and was standing outside her old harness — so I bought the Reflex set. The lead came with it, already sized to the harness, so there was nothing extra to buy. The reflective trim shows up clearly in headlights on a winter evening. The dual adjustment closed the gap she used to slip through, and I could fit it properly on a narrow-chested dog. Measure the chest girth behind the front legs — sizing matters more here than on a normal harness. We're back to daily walks, which I didn't expect. The product itself works well and is exactly what I ordered. The one-star rating is entirely for the delivery experience: it arrived extremely late, tracking stopped updating, and I received no clear delivery estimate.
