The Fortis Bivvy Shoe MK2 is a pair of cosy slippers designed for relaxing in the evening after a long day on the bank in muddy, heavy boots. If temperatures drop below freezing, they keep feet snug thanks to synthetic 3M Thinsulate™ insulation and a polar fleece lining. The DPM polyester upper carries a water-resistant DWR coating, while the TPR rubber outsole is lightweight and weather resistant, should you need to attend to the rods in the event of a bite. They are small and packable, so they can be carried in your kit and worn when you need something lighter and more compact. - Durable outsole provides traction for both indoor/outdoor wear - Water repellent - 3M Thinsulate™ Synthetic Down Insulation - Fleece Lining - Lightweight - Packable
