Product Information

The Mares Ultraskin Short Sleeve She Dives Rash Guard is a women's thermal undersuit top built with Mares' Ultraskin technology, designed to be worn alone for water sports or layered under a wetsuit or drysuit for added warmth and UPF 50+ sun protection.

Who it is for

It suits women divers who want extra thermal protection beneath a wetsuit or drysuit. It also suits water sports users who want sun coverage and protection against light friction. The short sleeve cut keeps the forearms free while still covering the torso and upper arms, making it a practical base layer for warm water dives or layering in cooler conditions.

Key details

Ultraskin construction combines three layers: a soft fleece inner layer for comfort against the skin, a breathable, windproof PU membrane in the middle, and an elastic outer layer for a close, freedom-of-movement fit. The fabric provides UPF 50+ sun protection and is rated by Mares for use both as a standalone water sports top and as an undersuit beneath wetsuits and drysuits.

Material: Outer Nylon/Elastane, mid PU membrane, inner Polyester/Elastane
Sun protection: UPF 50+
Sleeve length: Short
Compatible with wetsuits and drysuits as an undersuit layer

Compatibility and sizing

Available in women's sizes XS, S, M, L, XL, and 2XL, this rash guard is cut to layer easily under wetsuits and drysuits without restricting movement.

Frequently Asked Questions

Can the Mares Ultraskin She Dives rash guard be worn without a wetsuit?

Yes. Mares states it is suitable for water sports on its own, offering UPF 50+ sun protection and protection against light friction. It can also be layered under a wetsuit or drysuit when extra thermal protection is needed on a dive.

What is the difference between the short sleeve and long sleeve Ultraskin She Dives tops?

Both use Mares' Ultraskin technology; the difference is sleeve coverage, with this version leaving the forearms free. The long sleeve version has full-length sleeves instead of short sleeves.

What sizes does the Mares Ultraskin She Dives Short Sleeve Rash Guard come in?

This women's rash guard is available in sizes XS, S, M, L, XL, and 2XL; contact DiveCatalog.com for sizing guidance.

Does this rash guard provide sun protection?

Yes. Mares rates the Ultraskin She Dives fabric at UPF 50+, which blocks a high level of UV radiation, making it suitable for sun protection during surface water sports as well as under exposure suits while diving.

Size runs small. Go bigger.

Haven’t had a chance to open water yet. They are tight and seem to run small. I have another brand that bought L and had to return. These I bought M expecting similar, returned and am still tight in the L/XL

Great purchase and "Like New" as advertized.

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.
