I go with O'Neill boots and gloves all the way. They have these little gaskets on the inside that allows warm water to flow into your hands and feet but not out. They rock!
Yeah I have oneill mits and I like them but they got a pin hole in the right in between the index finger and the part where you other 3 go . I fixed them with some oneill wetsuit repair glue been fine ever since
i had a pair of 5 mm. hyperflex gloves last winter that were the worst junk ever..after about 3 freezing sessions i just gave them to a kid who didnt have any gloves.
i still havent really found a brand of gloves i like/are durable
