Sale price $201.59 Regular price $251.95

Product Information

The Mares Ultraskin Long Sleeve She Dives Rash Guard is a women's long-sleeve undersuit built with three-layer Ultraskin technology, designed to be worn on its own or layered under a wetsuit or drysuit for extra thermal protection, with UPF 50+ sun protection and a women's-specific cut available from XS to 2XL.

Who it is for

This rash guard suits women divers who want a low-bulk base layer for added warmth under a wetsuit or drysuit on cooler dives, as well as snorkelers and water sports participants who want UPF 50+ sun coverage and light friction protection during surface time or paddling, swimming, and other activities in the water.

Key details

Three-layer Ultraskin construction: an inner polyester/elastane fleece, a breathable and windproof PU membrane, and an outer nylon/elastane layer.
UPF 50+ sun protection for extended time in and out of the water.
Light friction defense during movement, suited to scuba and general water sports use.
Quick-drying, low bulk fabric that layers smoothly under wetsuits and drysuits.

Compatibility and sizing

The She Dives long sleeve is cut for a women's fit and is intended for use under wetsuits and drysuits, or as a standalone top. It is available in XS, S, M, L, XL, and 2XL.

Frequently Asked Questions

Can the Mares Ultraskin She Dives long sleeve be worn on its own without a wetsuit?

Yes, it can be worn as a standalone rash guard for sun protection and light friction defense during water sports, or layered under a wetsuit or drysuit for added thermal protection on cooler dives. The three-layer Ultraskin construction and UPF 50+ rating support both uses.

What sizes does the Ultraskin She Dives long sleeve come in?

It is available in XS, S, M, L, XL, and 2XL, cut specifically for a women's fit. Choosing a size that layers comfortably under your existing wetsuit or drysuit is recommended, so contact DiveCatalog.com if you need help checking fit against your current suit.

Does this rash guard provide sun protection?

Yes, it carries a UPF 50+ rating, which reduces sun exposure during surface intervals, snorkeling, and other time spent at or above the water's surface. This is in addition to its thermal and light friction protection benefits during diving and water sports.

What is the Ultraskin She Dives long sleeve made of?

It uses a three-layer construction: an inner polyester/elastane fleece for softness and warmth, a breathable and windproof PU membrane in the middle, and an outer nylon/elastane layer for a secure, flexible fit. This combination keeps the garment low bulk and quick drying.
