Our Ascend Sequoia Collar is both soft and flexible and is one of the most comfortable collars on the market. Being part of our Ascend line, it perfectly matches all other Ascend products and comes with the same reflective material and our exclusive, lightweight, super-strong (3X stronger than plastic buckles) anodized aluminum Side-Release buckle. It also comes with an oversized aluminum D-Ring that is significantly lighter than most steel D-Rings found on other collars on the market but is just as strong.
