CrookedHorn is superb. I have had both packs in hand and I can tell you that the Crooked Horn has much heavier dutyconstruction and materials and it also feels like it's more water resistant than the Superday. However, the Superday has quite a few desirable features that the Crooked Horn doesn't. I'm not sure a Superday is worth the extra money yet. You can't go wrong with Crooked Horn though. I've used min probably 120 days a year for several years and it's still like new just dirty lol....
