This is a well designed and well made canine garment. We purchased the large size in orange color. Wind and water resistant on one side with a plush orange-camo fleece liner on the reversible side. Heavy duty stitching all the way around looks like it will last a long time with proper garment care. Highly reflective striping and paw detail. Easily seen at night a quarter mile away. The coat fits far enough down the neck it doesn't interfere with collar and leashes. It does not interfere with him hiking or squatting to do any of his business. We took this dog in as a stray a month ago and soon realized he'll never produce a long/thick enough winter coat to keep warm when we're outside on cold or wet days, which is why we purchased this coat. So happy we did and will highly recommend the brand to all of our friends!I read numerous reviews on this product to get an idea on sizing. I also referred to the sizing chart and measured our boxer mix as indicated. He fell right in the middle of all the measurements for the large size. He is about one year old and weighs 52 lbs with a mostly boxer build. This large fits him nicely, and will leave room for him to put on another 8-10 lbs. I strongly suggest going by the sizing chart and measuring your dog, as it seems quite accurate.***UPDATE*** 4/10/18We've been using a Embark Active Dog Harness, Easy On and Off with Front and Back Leash Attachment Points & Control Handle - No Pull Training, Size Adjustable and No Choke (Medium - Orange) in conjunction with the coat on cold and rainy days and they work great together! The orange colors even match!
