PORTLAND — A designer T-shirt company has moved its operations from New York City to Portland.

Elykssor Clothing was started by Kyle Poissonier, a 2003 graduate of Skowhegan High School.

Elykssor is a name derived from the mythical “elixir of life,” touts the concepts of the renewal of youth and prolonging life in its T-shirt designs.

The Bangor Daily News reported the company started as a Husson University business school project for Poissonnier that took off when two of his friends jumped into the venture. In the past three years the company has seen steady growth in sales of its products in the U.S. and Canada.
