BUFFR Smart Ring Protector Silicone Ring Guard Size 13

BUFFR Smart Ring Protector is a slim silicone cover that snaps over Oura, Ultrahuman, RingConn and other smart rings to prevent scratches and absorb bumps while keeping sensors exposed.

When you wear a smart ring daily, accidental knocks, scuffs and grime are inevitable. The BUFFR Ring Protector is designed to add a low-profile layer of defense without blocking sensors, adding bulk, or changing how the ring feels on your finger. This size 13 black cover uses a hook-on fit and soft, skin-safe silicone so you can keep tracking performance and comfort through workouts, work shifts and everyday life.

How does the BUFFR protector stay secure during activity?

The protector uses a hook-on design that grips the ring body to resist slipping during motion. Its form-fitting profile conforms to the ring’s shape for a stable hold, so it won’t rotate or fall off during exercise, manual tasks or daily movement.

• Hook-on lip locks into the ring’s inner edge for non-slip wear
• Slim profile minimizes leverage that could dislodge the cover
• Flexible silicone stretches slightly for an easy on/off while remaining snug

Will the cover interfere with sensors or ring fit?

The BUFFR protector is engineered to be sensor-friendly: it cushions the ring without covering optical or contact areas needed for tracking. The slim design preserves the ring’s tactile fit so you retain accurate readings and a near-native feel.

• Openings and thin silicone over sensor zones maintain signal access
• Sizes match common smart-ring dimensions for correct contact and fit
• Low-profile height preserves finger comfort and range of motion

How does the silicone material affect comfort and durability?

BUFFR uses soft, skin-safe silicone that reduces impact and resists everyday wear. The material breathes, flexes with finger movement, and is easy to clean so the cover stays hygienic and comfortable for prolonged wear.

• Medical-grade-feel silicone remains soft against skin during long hours
• Durable against scuffs, abrasion, and minor impacts
• Wipes clean with mild soap and water; quick to dry
