I'm not wild swimmer. I bought it because I needed something long, warm, waterproof to survive Yorkshire weather. It works like a charm. Now when I'm sitting on a bus stop, in wind or rain, I feel like I'm wrapped in cosy blanket.
Love the pockets that hold SOOO much. Keys, phone, mittens, tissues, lip balm, pen, change, another mittens, charging cable, and it all is still on the bottom! I believe I could pack my lunch there!
Zippers on sleeves are useful with my crutch when it is not too cold....
