"Extra 40% off" with SUMMER40 code (posted at the site). The Depactus Aleutian boardshort is worth a look (largely welded construction, stretch, see Depactus) at $22.50 and the Depactus M.E.P. boardshort is a bit fancier at a considerably higher price, $45.  Both might be good camo in a kelp forest.  They have shirts like that, too.
