Solumbra is a line of sun protection clothing and patented fabric that was introduced in 1992.
History
Shaun Hughes, a melanoma patient, developed the Solumbra line of fabric and clothing. He felt that traditional UV protection was insufficient, as he would tan through
sunscreen and get
sunburned through his summer clothing. Solumbra clothing designs are based on published medical guidelines.

Research
R. Sayre was the lead researcher of ''
in vitro'' SPF testing for traditional summer fabrics. This revealed that traditional summer clothing in North America offered less than 15 SPF protection, the minimum level recommended by doctors. These traditional summer fabrics tested between SPF 59 when dry and SPF 39 when wet. Nicholas Lowe and R Sayre followed this up with ''
in vivo'' research to find that Solumbra achieved over 50 SPF when dry or wet.
''In vivo'' research spearheaded by J Menter and Sayre, published in the ''
Journal of the American Academy of Dermatology'', showed that most mice contracted squamous cell
carcinoma (SCC) skin cancers through typical summer fabrics, and mice protected by Solumbra fabrics did not incur skin cancers. Subsequent research by Menter and Sayre found that specific Solumbra fabrics provided photoprotection for mice against injury from visible light when sensitized with the
photosensitizer,
ALA, compared to insufficient protection by typical summer fabric.
