Green mesh harness with rope trim and adjustable straps for small dogs

AirFlex Harness

$24.99
$24.99

The AirFlex is a breathable mesh harness with a lighter, more active feel than soft wrap-style models. The airy mesh build keeps your dog cool, the low-bulk construction allows free movement, and reflective detailing adds visibility on darker walks. It features a back D-ring leash attachment and multiple adjustment points for a secure, dynamic fit. A matching 1.5m pet leash is included. Manufactured by Duomm, a brand recognized for the quality and comfort of its harnesses. Available in sizes S, M, L, and XL across the small-dog range.

The AirFlex comes in sizes S, M, L, and XL, built for the small-dog range. Always measure your dog before ordering rather than choosing by weight alone, since chest girth is the most reliable guide.

Size Weight Chest Neck
S 1.5–3 kg
(3–7 lbs)		 34–40 cm
(13–16 in)		 34–40 cm
(13–16 in)
M 3–4.5 kg
(7–10 lbs)		 34–46 cm
(13–18 in)		 34–46 cm
(13–18 in)
L 5–7.5 kg
(11–17 lbs)		 42–52 cm
(17–20 in)		 42–52 cm
(17–20 in)
XL 7.5–10 kg
(17–22 lbs)		 42–58 cm
(17–23 in)		 42–58 cm
(17–23 in)

To measure: wrap a soft tape around the widest part of the rib cage, just behind the front legs, for the chest girth. For fluffy or long coats, measure under the coat, not over it. The harness should sit snug with two fingers fitting underneath comfortably.

Stay Cool and Move Freely

Active small dogs need a harness that keeps up without weighing them down. The AirFlex is built around breathable mesh and a light, low-bulk design that lets air flow through and keeps your dog cool on warmer days and longer walks. It sits between a basic mesh harness and a heavier structured model: more dynamic and supportive than the lightest options, but never bulky. The flexible build moves with your dog, and reflective detailing keeps them visible on early or late walks. It's a natural fit for Pomeranians, Shih Tzus, Toy Poodles, Bichons, and Cavaliers who run warm under their coats. If your small dog is active and you want airflow plus everyday comfort, the AirFlex delivers both.

F.A.Q

Yes, every AirFlex includes a matching 1.5m pet leash, ready to use straight out of the box. No separate leash purchase needed for everyday walks.

Yes, the breathable mesh build is designed for airflow, which helps keep your dog cool on warm days and during active walks. It's a strong choice for summer use, warm climates, and small dogs who run warm under a thick or long coat.

The AirFlex uses a back D-ring and is built for breathable everyday comfort rather than pull control. For strong pullers, a front-clip no-pull design suits better. The AirFlex is ideal for active small dogs who walk well and need airflow and freedom of movement.

The AirFlex comes in sizes S, M, L, and XL, fitting a chest girth from 34 to 58 cm (13 to 23 in) and dogs from 1.5 to 10 kg (3 to 22 lbs). Measure your dog's chest before ordering and check the Fit and Sizing menu above to find the right size.
