I received a new rocket 4 sleeveless suit and I love it and highly recommend it. The fit is great for me. XL -6' 200lbs. I want to thank sailfish for their amazing customer service support when my first order was lost by USPS. They responded to my email right away and got everything taken care of in a very timely manner. Thank you again. It's nice to know there are still great companies like this.
First time buying from the company. Two fellow triathlons recommended them so I took a shot. I’m glad I did. I bought the Men’s Rocket 4 sleeveless. I love it! It’s lighter than my previous one and fits better. It goes on very easy. The size chart are perfect for me.
This suit is awesome…fits great, soft and high quality. Just got the full Arctic…why am I wishing for colder water?

Sizing Tips
Finding Your Perfect Fit – Your wetsuit should feel snug but never restrictive. For the best performance and comfort, you want a close fit with no loose areas or wrinkles. Height and weight are your starting points, but your body shape and swimming style matter too. Between sizes? Give more emphasis to weight over height.
We've refined our size chart based on thousands of real-world fittings and athlete feedback. The result? A much more precise size chart that better matches your natural shape and swimming style.
