Just got the new Oura Ring 5? Keep it flawless from day one. This case is precision-molded for the 2026 Oura Ring 5 - the redesigned ring is 40% smaller than Ring 4, so older Gen 3 and Gen 4 sleeves will not fit. Why Oura owners choose it: - Ultra-thin, low-profile fit - soft silicone hugs the ring without adding noticeable bulk, comfortable enough to forget you are wearing it. - Stays put - stretch-fit silicone grips the ring so it will not twist or slide off during workouts, chores or sleep. - Real scratch protection - shock-absorbing silicone takes the hits from dumbbells, door handles, keys and desks, keeping the titanium finish and resale value intact. - All-day comfort - odorless, sweat-resistant, skin-friendly silicone, gentle enough for 24/7 wear. Sizing: choose S for Oura Ring 5 sizes 6-9, and M for sizes 10-13. Not sure? Check your size in the Oura app or the Oura sizing kit, then see our size chart image. Slip one on in seconds, swap colors to match your day, and never stress about scratches again.
