Product Information

The Mares Trilastic Long Sleeve Rash Guard is a men's long-sleeve rash guard built with UPF 50+ sun protection for diving, snorkeling and general water sports. It uses a lightweight, quick-drying Nylon and Spandex fabric with flat-lock seams designed to move with the body without chafing.

Who it is for

This rash guard suits divers, snorkelers and water sports enthusiasts who want sun coverage on the arms and torso without the bulk of a wetsuit. The quick-drying fabric and soft flat-lock seams make it a practical layer for warm water dive trips, boat days, paddleboarding or any activity where UPF 50+ sun protection and freedom of movement both matter.

Frequently Asked Questions

What does UPF 50+ mean on the Mares Trilastic Rash Guard?

UPF 50+ means the fabric blocks the vast majority of the sun's ultraviolet radiation, allowing only a small fraction to pass through. For this rash guard, that rating gives divers and snorkelers strong sun protection on the torso and arms during surface swims, boat rides and shallow water sports.

What sizes does the Mares Trilastic Long Sleeve Rash Guard come in?

This men's rash guard is available in S (Small), M (Medium), L (Large), XL (X-Large), 2XL (2X-Large) and 3XL (3X-Large).

What material is the Mares Trilastic Long Sleeve Rash Guard made from?

It is made from a Nylon and Spandex blend that is lightweight and quick-drying. The fabric is finished with flat-lock seams that lie soft against the skin, reducing irritation and friction during paddling, swimming or diving movements.

Is the Mares Trilastic Rash Guard only for sun protection, or does it add warmth?

It is made for UPF 50+ sun protection and comfort. Mares describes the material only as lightweight, quick-drying and comfortable for water sports.

Excellent wetsuit but will it crush quickly like other wetsuits?

I purchased a BARE 5mm Reactive wetsuit (open box), which was like new, to replace my 1.5 yr old BARE 5mm Velocity wetsuit which had collapsed to only 2.5mm after 3 diving trips (~100 dives). The Reactive wetsuit is well constructed and very flexible. I had to increase the size of the Reactive suit, as it was smaller than the BARE Velocity suit of the same size. Tremendous customer service by Dive Catalog to exchange the wetsuit for proper size. I hope the Reactive suit does not crush so quickly like my other wetsuits (BARE, Henderson, Pinnacle). Hoping that the new technology in this suit will keep me warm below the thermocline.

Perfectly Built

Best of the many many diver hangers in my life. Easily supports my steel-plated BCD, while still donned with all of my accessories. No cracks, bends, or dents. Has even supported my BCD w/ a steel 100 tank attached (not recommended, for safety purposes, though).

Will continue to use this hanger for the long-term. No brainer.

Go-to Dive Hanger

This is a must-have for every diver. It's the quintessential hanger for all dive gear in one small package.

DiveCatalog's "Quick Dry Multi Accessory Dive Gear Hanger for Boots, Gloves, Hood" is set at a great price for a great product. Versatile enough that I've purchased extra hangers to organize my BMX racing gear.

Must-have for divers and anyone looking to organize their adventurous outdoor activities equipment.

Solid Hanger w/ Tons of Options

Does it's job and then some. The added accessory arms gives you options for a multitude of storage solutions. Solid build, solid pricing, must have for owns of dive gear.
