Best quality is super stretchy in shoulders. Paddling getting tired no issues. Knees are great material. Easy entry and taking off. Great sipper action. Drys we'll overnight. No rash. I've been surfing So Cal for 42 years and I have purchased every brand. I do not need any other brand wetsuit then Quicksilver my absolute favorite. I have spring short sleeve 2mm, short john2mm, and full suit short sleeve 2mm. I want a long john 2mm and I'm complete.
