Olive Green Dog Life Jacket, 3x Foam Cube Design
Our olive green dog life jacket carries the 3x foam cube design, a layout we drew for the body of a swimming dog rather than borrowed from a human vest. It is built on the flotation principles of human life jackets, and our team tested its buoyancy in house before it reached a customer.
The idea began with Luna, our Cavalier. She went overboard on a boating trip and struggled to keep her head above the waterline in the vest she had on. We wanted a jacket that answered that day.
Olive Green is a quiet shade for lake days, river walks and boat decks, and the jacket fits cats who join you on the water too. See every color in dog life jackets, or compare this shade in the 4x olive green life vest.

Inside the olive green dog life jacket
Every jacket shares the same buoyancy. The 3x layout spreads its foam in the pattern below.
- 3x foam cube design, made for dogs, shaped for buoyancy and free movement
- Same buoyancy and the same amount of foam as our 4x design. Only the layout differs.
- Built on the flotation principles of human life jackets
- Buoyancy tested in house by our own team
- Works in any water, from the pool to the open sea
- ColorOlive Green
- Sizes XS to XL, chosen by ribcage girth

Caring for your life jacket
- Rinse the jacket in fresh water after each swim to clear away salt, chlorine and sand. Let it air dry completely before you put it away. Do not tumble dry.

Life jacket size guide
| Size | Ribcage girth (in) |
|---|---|
| XS | 11 to 15 |
| S | 16 to 20 |
| M | 21 to 27 |
| L | 28 to 32 |
| XL | 33 to 44 |
Choose by your dog's measurements, never by weight. Wrap a soft tape around the deepest part of the ribcage, just behind the front legs, and match that number to the chart.
