THESE SHORTS ARE MADE FROM AN ORGANIC COTTON AND SEACELL™ FIBER MIX. SEACELL™ (C-FIBER™) IS A BIOBASED FIBER CONTAINING SEAWEED AND EUCALYPTUS. THEY ARE TREATED WITH PEPPERMINT OIL (PPRMINT™) TO KEEP THEM FRESHER FOR LONGER. THEY ARE CUT IN THE SAME FIT AS OUR CLASSIC 365 SHORTS SO THEY CAN BE WORN INDOORS OR OUTDOORS.
