IECOii XXXLarge Green Dog Winter Jacket with Built-In Harness and Reflective Straps

IECOii XXXLarge green dog winter jacket is designed to keep large dogs warm and visible on cold-weather outings, with an integrated harness and a step-in, zip-up design.

• Insulating polar polyester lining and a turtleneck collar — wrap your dog in warmth in cold weather.
• Windproof, waterproof outer — helps keep your dog dry and clean in rain or snow.
• Reflective straps on the back — make your dog more visible in low-light conditions.
• Built-in harness with adjustable straps and a sturdy D-ring — combine a coat and harness in one garment.
• Two small back pockets — keep small walking essentials close at hand.

This winter coat is made for large dogs heading out for everyday walks, evening outings, or outdoor activities in cold, wet, or low-light conditions. Its integrated harness avoids the need for a separate vest harness, while the back zipper makes dressing easier for dogs that dislike pull-over coats.

How should I choose the XXXLarge size?

Choose the size by your dog’s chest girth first: XXXLarge fits a 41.34-inch (105 cm) chest, with a 26.8-inch (68.1 cm) back and a 26.8-inch (68.1 cm) neck. Measure your dog before choosing; breed and weight are not the primary sizing guides. The XXXLarge size is suited to big dogs such as Golden Retrievers, German Shepherds, Pyrenees, and Great Danes.

• Chest: 41.34 inches (105 cm)
• Back: 26.8 inches (68.1 cm)
• Neck: 26.8 inches (68.1 cm)

How do the coat and built-in harness work together?

The IECOii dog coat has adjustable harness straps and a sturdy D-ring, bringing the winter layer and harness together in one design. Strengthened seams and the D-ring are designed to withstand strong pulling force. The reflective straps on the back support visibility during low-light walks and outdoor activities.

• Use the adjustable straps to set the fit.
• Reflective back straps suit night walks, hiking, camping, and hunting.

How does the jacket go on, and what can it carry?

The step-in design and back zipper allow quick dressing and removal. A protective fabric layer beneath the zipper helps prevent hair from snagging, making this style a useful option for dogs that resist traditional pull-over coats. Two small pockets on the back hold compact essentials such as poop bags, treats, keys, or small toys.

• Zip-up closure for dressing and removal.
• Two small back pockets for walking essentials.

The IECOii XXXLarge green winter jacket suits owners of large dogs who want warmth, rain and snow coverage, reflective visibility, and a harness in one coat. Its measured chest, back, and neck dimensions help guide fit, while the step-in zipper and back pockets support practical walks and outdoor outings.
