Immersion Research's Guide Shorts are the classic board short built for paddlers. This is the original IR product- the one that IR started with 14 years ago. Lace-up waist with just a small circle of velcro on the fly, deep gusset crotch for a siting position, made with quick-drying rip-stop polyester microfiber, and the signature ‘biner-sized brass grommet on the back leg-perfect for clipping the short to the rest of your gear, or for hang-drying. Immersion Research's guide shorts are also liner-less- any river guide can tell you how itchy mesh liners can get after a week of use.
