I created leggings with this design and decided it would also be great on a rash guard shirt.  You can wear them together as a set, or separate, but such a great look either way.  

• 82% polyester, 18% spandex
• Very soft four-way stretch fabric that stretches and recovers on the cross and lengthwise grains
• Fitted design
• Comfortable longer body and sleeves
