The Tech Double Slim Plus is the travel surf bag every surfer needs. Now upgraded to a coffin style YKK molded zipper and heavy-duty woven silver reflective side, this is a Coffin spec bag disguised as a single board bag.The design is the same feature-rich, travel tested specification from Roam’s Tech bag. The Double Slim also has an expanding hidden sidewall to convert from a single to a double board bag and back to a single in an instant. Unless you are traveling with a pros full quiver, this is the ultimate travel bag.As with all of Roam’s bags it is cut longer so a bag will fit the size that it is labelled for.ie. a 68 bag will fit any size up to and including 68 so you can carry your groveller and your step up when checking the surf.
