This is a Billabong semi-dry wetsuit (5x3mm). It's a domestic L size, authentic product. Made of rubber, it keeps you warm even on windy days. Thanks to the wing zip, it's very easy to put on and take off! I bought it last year and used it for 9 days this season. There are no noticeable stains or damage, and the rubber is still soft with no deterioration. Same-day shipping is available.
