The 200g Horseware Optimo liner is perfect for adding warmth to your Optimo turnout during those colder temperatures. The 200g liner is also designed to be breathable and moisture-wicking, and incorporates the same "Split Technology" as the best selling turnout, keeping your horse comfortable and dry throughout the day. With its easy attachment and detachable design, adding or removing warmth to your Optimo blanket has never been simpler.  This liner can be used on ANY Horseware Ireland blanket, not just the Optimo, and can be used if you want to give your horse a little more freedom in the shoulder when layering.
