Gardener's Supply has some on target products but this isn't one of them. The best way to line a raised bed is with impervious plastic sheeting, rather than one that allows water to drain.
This product assumes top watering when clearly the best way to irrigate a raised bed is by sub-irrigation.
Have a look at this Flickr photo set to see sub-irrigated raised beds and other types of SIPs.

Use a Raised Bed Anywhere with Grow Bed Liners
Sized to fit our Grow Beds, these liners keep soil contained so you can install beds on a patio, paved area or concrete slab — any hard surface — without soil washing out and making a mess. They prevent weeds from infiltrating beds set on the lawn, too. Made from patented, double-layer polypropylene fabric that allows water to drain.
