These multi-purpose thermal sit mats are designed to give you a warm, dry place to sit - no matter the location! You can also use them to protect upholstery from muddy boots, wet bums, or soggy dogs. Created by Rubbastuff (who also make the OS Picnic rugs), these sit mats have three layers: Soft, technical microfibre quick dry top for comfort Warm middle Thinsulate layer for warmth Waterproof, tough tip-top nylon bottom for protection. They also weigh only 100g and pack into their own mesh bag, snuggly fits into most pockets and is enough space for one person. Use it for sitting on, as a changing mat, for kneeling while gardening, as a seat protector, or a comfortable place to sit in the park. Made in UK.
