So happy with this suit. I bought in Metallic Green with attached toe socks and gloves. 0.4mm. Make sure you use a lot of lube with this one - getting into it took a lot of effort. The trick is to get a lot of lube in the suit, without getting much inside the gloves so you don't lose any dexterity. But wow, once on it was amazing - like a second skin hugging every crevice. Suit seems very well made - I've only tried it on once, so we'll see how it holds up to wear and tear. Took a very long time to get the suit off. It helps to take it off in the shower using water as a lubricant. Fast shipping to Canada too! Very happy with my purchase.
