Product Information

The Waterproof R30 Long Sleeve Rash Guard is a men's lycra and spandex top built for scuba diving, snorkeling, and other water sports, offering 50+ UPF UV protection, flatlock stitching, and ten-panel construction for mobility whether it's worn wet or dry.

Who it is for

This rash guard suits divers and snorkelers who want sun protection and chafe reduction during warm-water sessions, as well as anyone who needs a thin, quick-drying base layer under a wetsuit. The stretch from the spandex/lycra blend keeps the fit close without restricting movement, making it a practical layer for regular diving, snorkeling, or surface water activities.

Key details

UV protection: 50+ UPF
Construction: Ten panel design for a secure, mobile fit
Stitching: Flatlock stitching to reduce chafing

The men's R30 Long Sleeve Rash Guard is available in four sizes: XS/S (X-Small/Small), M/ML (Medium/Medium Large), L/XL (Large/X-Large), and 2XL/3XL (2X-Large/3X-Large), so divers can match the fit to their body type and layering needs under a wetsuit.

Best Rash Guard I've Ever Used

After trying on several Rash Guard tops at several shops, this Rash Guard fit me better than any of the others and I free-dived o Orcas and Mobulas in the Gulf of California for a week in it I wore it all day every day. It is the best Rash Guard I've ever owned. However, I would like Waterproof to make matching bottoms for this item.
