David wrote a review of The North Face Rock 22 Footprint on December 7, 2009
Best darn thing you'll ever buy. I rarely use the actual tent in our warm weather and with this custom footprint, the fly only works great, packs down light and pretty small and the footprint is very durable for what it is. i've used mine for about 30 nights, in the real outdoors, without any tears or rips. very waterproof as well.
