"Essential if leaving Karu 12 outside" star star star star star We’ve kept our Ooni Karu 12 outside between cooking sessions and this cover is indeed 100% waterproof as claimed. We plan on storing our Ooni oven in an outbuilding over winter but during our British summer with often rainy weather, this accessory has been great! We haven’t tried using the cover to carry the oven about yet but are confident it would be fine. Sturdily-made and covers the oven very neatly indeed. The seam lines are all sealed internally, preventing water getting in through the stitch holes or fabric joins. Highly recommended.
"Handy Ooni Accessory" star star star star star_border It's a nice Ooni accessory to have if you are using the oven elsewhere and not just at home - the Karu is quite heavy and a bit awkward to carry otherwise, especially with the chimney, so the handles make it easier. Otherwise, not sure if a cover is really helpful (ours is in the garage when not used to extend the life of the product, but it could be kept outside (according to Ooni). Supposedly it's waterproof (we haven't tested that), but it's made of thin nylon without any padding (so no added protection whilst in transit).
