the NUT : weatherproof
You should not be limited to simply using your iPhone indoors or in fair weather. You should be free to take your iPhone out and about and use it regardless of circumstance or weather conditions. The NUT has been designed to allow you to do exactly that. Your iPhone is protected against severe weather and the ingress of sand, dirt and grit.
We’ve even had it tested at a bona fide test house (complete with white coats and safety specs!) to IPX4. It passed with flying colours so we can confidently say that the NUT has passed the IPX4 Water Ingress Test in accordance with BS EN 60529:1992 (completely weatherproof in layman’s terms).
