The Next Generation of Fabrics.

A New Generation of Designer Dog Coats-Fabrics specially designed for defense against all kinds of weather.


At MountainMuttDogCoats  Boulder we carefully consider the fabrics we select for our winter coats and designer dog sweaters.  They are chosen to meet the needs of the wearer. Our coats and sweaters have been carefully designed to offer the individualized protection needed.  New fabrics are always being created. We stay on ahead of curve in comfort and warmth!

The design and function of a garment affects the choice of material.  The material is a significant part of the garment. Two pieces of clothing made from the same pattern but of different fabrics can perform very differently.  We choose our material according to what we want the garment to look like and do.  All materials are not suitable for all styles.

Technical Fabrics.  The use of a garment is an important factor to keep in mind when choosing the fabric.  Because our  coats and sweaters need to be easy to wear we pick light weight technical fabrics that are comfortable for your dog. Technical fabrics are engineered to do a variety of jobs including elimination of unwanted moisture, retention or release of heat, resist abrasion, resist wind, resist water, or keep your dog visible and safe.  For example,  we use PowerShield for one of our winter coats because it’s highly water resistant, maintains stable core temperature and is very lightweight.  Our Powershield Hunting Gear is all this plus it’s orange.  It’s safer because of it’s high visability.  Our garments need to be durable. We choose fabrics that are designed to last.  Because we expect our coats and sweaters to last a long time we use only the best quality fabrics even though they might cost a bit more.

Power Shield is our top-of-the-line softshell.  Power Shield is designed to maintain stable core temperature during varying levels of activity.  It’s a two-sided fabric that provides superior protection from water and wind. It has a membrane that expands and contracts to release/retain warmth depending on activity level.   This is the fabric of choice for a winter coat for an active dog.  The exterior is abrasion-resistant. It won’t snag on branches and fences. We run it under the faucet to demonstrate how water beads off the surface. Try it yourself.

PolarTec Fleece is a wonderfully warm fabric for cold weather. It’s available in different weights and can be worn alone or combined with an exterior layer to create a warmer garment. We use Polartec 300 in our Boulder Coat, Boulder Sweatshirt and  Boulder Sweater.  Polartec 300 is often called the best insulating fleece made. Combined with a ripstop exterior it becomes a lightweight, durable, warm and water-resistant winter coat. The Boulder Coat is the right choice for a less-active dog.  It’s great for senior dogs too.

Polartec 100 is feather-light, soft, warm and comfy. The post-op Smart Sweater is made from this lovely, yielding fabric. It’s meant to be worn indoors in chilly homes and post-op.

Ripstop is a polyester fabric that is super light. It’s durable, run-resistant and makes a great outer layer for any garment. Our fabrics are made from recycled materials when available.

Windbloc is an amazing, rugged fabric that blocks 100% of the wind.  It’s a two-sided fabric with a polyurethane membrane between layers that assists with the transmission of unwanted moisture. Very warm, very protective in winter.

All of our fleeces are non-pill and durable. They feel delicious and will comfort your dog in a variety of conditions.


Taking good care of a garment is also essential. All of our garments can be harmed by high temperatures and harsh chemicals in the washer or dryer.  They should be washed cold, with Woolite and line dried or dried on a cool cycle.   Hang the garment in the bathroom where it’s damp and the wrinkles will come out.
