Sundridge SAS Mk7 Flotation Jacket Sundridge is the largest supplier of flotation suits in Europe and this SAS Mk7 jacket is just one of the many incredible products the brand produces. Set to be the biggest selling flotation jacket in both the UK and continental Europe, the SAS Mk7 has full EU buoyancy certification (CE EN393). The host of additional safety features include a warning whistle, to attract attention in cases of emergency, and the jacket is covered in 3M reflective tape. The outer layer of the garment is constructed from 210 denier Oxford Nylon. This is 100% waterproof, with a rating WP5000, meaning it can withstand an astonishing five meters of consistent water pressure over a 24 hour period before leaks occur. The jacket also has a MVP10000 breathability rating too and is able to disperse 10,000 grams of moisture vapour per square meter of fabric. In short, this jacket will keep you dry without making you clammy. The polyester body lining insulates you and the polar fleece lined collar stops cold air entering the garment at the neck. Neoprene cuffs stop the risk of water leak up the sleeves and the SAS Mk7 also features reinforced elbows to extend the lifespan of the jacket, significantly reducing the risks associated with wear and tear. Two inner pockets keep all your valuables safe and dry next to your body and two outer pockets allow you easy access to your tackle and other items when you need them. Adjustable waist and hood cords mean that you can fit the jacket as flush to the skin as possible. A two way zipper, manufactured by the worlds leading zipper manufacturer YKK, enables you to easily zip and unzip the garment. Polar fleece hand warmers trap warm air around your hands and help insulate the entire suit. All in all, the SAS Mk7 from Sundridge offers incredible safety features at staggering value for money.
