Rain stops being a reason to stay in.

The Ain™ Coat is Merlot's patented all-in-one raincoat — collar and coat in one, on in seconds, no separate harness to wrestle. A 20,000mm waterproof rating and fully seam-sealed construction keep the weather out; a movement-first cut keeps your dog comfortable for the whole walk.

The martingale collar stays relaxed at a walk and tightens on a sudden pull; rotate it for the anti-pull function in training. An arch-cut pattern adds 2–5cm of back length for longer bodies, and a 3D foldable snood shapes around the head and ears.

  • Patented Ain™ all-in-one design (since 2021) — no separate collar or harness
  • 20,000mm water resistance, KOTITI certified · ultralight 3-layer breathable DWR membrane
  • Full interior seam-sealing — every stitch line taped
  • Up to 580kg tensile strength · 18 reinforced bar-tacks · 3M night-reflective detailing
  • Harness-compatible · fits dogs up to 50kg

Material Polyester 100%, ultralight 3-layer membrane. Designed by Merlot Studio Inc. Made in Vietnam.

Care
  • Not machine washable
  • Spot-clean light marks with a wet wipe or neutral detergent
  • For a full clean, hand wash gently in lukewarm water (20–30°C) with a neutral detergent; frequent washing can reduce water repellency
  • Refresh performance with an outdoor DWR spray
  • Some tick-spray chemicals can degrade the waterproofing
  • Air dry out of direct sunlight; no dryer, no ironing

20,000mm Waterproof Rating

Engineered with next-level technology, this ultra-lightweight 3-layer membrane material perfectly shields the skin from harsh wind and rain.

Full Seam-Sealing

Flawless Protection with Full Seam-Sealing
Every single stitched seam, where minor leaks could potentially occur during heavy downpours, is meticulously seam-sealed. Utilizing the premium seam-sealing technique and a 5mm nano-seam design typically reserved for high-end waterproof jackets, it prevents the fabric from clinging to the skin, delivering all-day freshness and a comfortable fit.

“So cute!! Now I actually look forward to rain.”

“Thanks to the Merlot raincoat, our dog enjoys her walks even on rainy days.”

merlotstore.com · 2024-10

“It's waterproof but a thin material, which actually makes it more satisfying. Other raincoats feel a bit stiff, but this one is soft and drapey, the color is pretty, and my dog doesn't seem uncomfortable in it either!”
