Design Concept: The design features rainbow stripes that are fashionable and versatile, with a three-dimensional cloud pattern on the collar adding a unique touch. It also comes with an attached leash clip for convenient outings. Product Information: It is made of breathable and soft jacquard mesh fabric, suitable for summer use. The vest-style design is elastic-free, lightweight, and short in length. Size Chart: Available in six sizes (XS, S, M, L, XL, XXL) with detailed measurements for chest circumference and back length. For example, the XS size fits pets weighing 1-3 pounds with a chest circumference of 30cm and a back length of 20cm. Measurement Methods: To ensure the correct size, measure the dog's chest circumference at its widest point, the back length from the neck to the base of the tail, and the neck circumference around the neck. Add 2-3cm to the measured values for a comfortable fit. Comfort and Style: The hollow-out fabric ensures breathability and comfort, making it perfect for hot summer days. The stylish design not only looks good but also keeps your pet cool.
