I had those... I wasn't impressed. Where I sail the water is about 36 F and wind is usually about 15-20. The gloves I use are Gill extreme sailing gloves. They are awesome. Once your hands heat up the gloves, you'll be warm all day. To avoid that period of cold, I run my hands and gloves under hot water before I go sailing... Hands stay warm all day. Another cool thing about these gloves are that there is a lot of grip so it's not too much of a hard transition from fingerless gloves to these.
