Measures 1750 x 900 x 300 high
D rings to tie down to roofrack, three straps across the width, tonneau material, 3 sided zip.. took me a while to get the design right, we changed it many times, but this is now just what I wanted.. can fix it down with the D rings and zip ties, or use the 3 width ways straps. The ¾ size allows you to walk around the front/ back, and one side of the rack.. for me, this is important, so I can get up there, and sort things out, without standing on the bag.. also, there is just enough room to pack an Oztent down one side (which you can walk on if needed, but it can lift on last) also at the front, I have some max trax, which you can also walk on, so this seems a real handy size.. we make the bags in our Drifta canvas factory, so if you wanted it slightly larger, longer etc, we can do that.. we are now using a black torneau material, which stands up to the wind much better than pvc.. three sided zip makes for easy access.. I wouldn’t say these are totally waterproof, as in driving rain, on a roof, doing 100 km/h, some water may get in around the zip, but with the 50 mm valance hanging down over the zip, not much.. it’s the best we can do, mostly what is stored up there, can on the odd occasion, cope with a small amount of water… this will fit on most roofracks, again, if you need one slightly larger/ smaller, then let me know.. thanks very much, luke
