I burst 2 zips on my cheap suit and called Ian about ordering 1 is the Sentinel II suits. He was ever so helpful on the phone about correct size etc. I ordered it that night at about 1900 and Ian messaged me the next morning to say it had been shipped and it arrived the next morning. Staying up in the NE of Scotland I never expected it that quickly. As for the suit all I can say is the quality is top notch especially for the price. I have a friend that has a suit that cost more than double this suit and side by side I would have the Sentinel II any day.
