Weather-resistant outer (rain + wind protection for unpredictable days)
Built to last (premium materials, hardwearing trims, designed for years)

Introducing The Core Gilet, the lightweight insulated mid layer of the Delta Roam Modular Outerwear System. Designed to add warmth without unnecessary bulk, it can be worn on its own or zipped into The Drift Parka when you need an extra layer.

Filled with lightweight, responsibly sourced insulation, The Core keeps your body warm while leaving your arms free to move. As a standalone gilet, it is ideal for walks, commuting, weekend sport, travel and everyday outdoor living. When temperatures fall, it zips seamlessly into The Drift Parka to add warmth while keeping the same comfortable, easy-to-wear fit.

True to our DNA, utility is woven into every detail. Warm external hand pockets provide comfort on cooler days, while our signature four red internal pockets keep everyday essentials organised and secure. At the back, a signature red D-Ring provides a practical hanging point and a subtle Delta Roam detail.

One of The Core's defining features is its packability. When no longer needed, the gilet folds neatly into its own integrated pouch to create a compact bundle that can be stored inside a backpack, clipped onto your bag or packed away until it's needed again.

From cool summer evenings and crisp autumn mornings to layered winter adventures, The Core has been designed to adapt with you. Sophisticated engineering, lightweight performance and considered functionality combine to create a layer you'll reach for throughout the year.

Available in Forest Green and Anthracite Black.

THIS IS NOT A DRY

"THIS IS NOT A DRY ROBE. It's a heavy winter coat. It's warm, it's made well, though the pockets could be more conveniently located. The zipper is a little annoying but it works well. You just have to line it up perfectly. This winter we've had -40F winter days and this coat has made the winter enjoyable, especially with a dog who loves the cold weather. But if you are looking for a dry robe or medium weight coat this is not the product for you."

I love it even more

"I love it even more than I thought I would! Medium was too big and needed to be exchanged. The Delta team was awesome communicating and sending a shipping label. The small came along in a timely manner. I wore it through a rain storm and stayed perfectly dry. I love the way it looks and feels this company is a 10.!"

"This coat makes walking my dog in the cold, sleet-y rainy weather a joy. What weather? I can barely feel the cold and wet outside."

I live in the Southern

"I live in the Southern US and this arrived the day before Winter Storm Fern 2026. We received 8 inches of snow and sleet. Then sub-freezing temperatures. This coat was AMAZING! It is a little tricky to align the zippers BUT it is well worth it to stay dry and warm. I believe this is a “stand the test of time” coat."

— Blake W. (5/5)

As a dog walker with

"As a dog walker with two very active labradors, I can honestly say, this coat is one of the very best things I have bought myself. With the horrible weather we’ve been experiencing in the UK in 2026 so far, I have been kept warm and dry. All the pockets help me keep my phone and keys dry while leaving enough room for tissues, poo bags etc. I only wish I’d have bought one sooner. Highly recommended."

— Julie S. (5/5)

Absolutely love this coat. I

"Absolutely love this coat. I bought it for lacrosse fall season and it did not fall on how warm and rain protective it was. Just came in from shoveling in blizzard conditions in Boston and guess who is dry. Me due to the coat."

"Good size, warm and waterproof, lots of pockets, useful velcro as well as zip. Bought for dog walking - happy with product"

— Jackie (5/5)

high quality! the robe details:

"high quality! the robe details: inner lining, sleeve w velcro adjustables and inner pockets are wow. even the length is very good. I'm 5'6, 124 lbs. Size small was just right."

— Cecille S. (5/5)

Even though it’s an investment

"Even though it’s an investment price wise, it has been worth it. I’ve worn it in single digit or below temps with only a t-shirt underneath and stayed warm. The hood is nice and deep to protect from wind and the elements. It’s kept me dry in the rain and snow. Zipper needed a little working at first but is great now. If using to be able to change while in, maybe order a size up."
