Our outdoor range is made from high quality, durable outdoor fabric which is water resistant but NOT waterproof! So while a little water is ok, it’s best not to leave your Happy Sak in the rain as this will damage the cover and the foam filling. Our indoor range is not water resistant so shouldn’t be used outside, unless under a covered patio. As for the sun, it’s also not advisable to leave your Happy Sak in direct sunlight as it will fade over time.
