iPhone 17 Pro ケース - ヘビーデューティークロスボディフォンケース - Casebus クロスボディシリコンフォンケース、調節可能なランヤードストラップ付き - DOLORES - Casebus

Took this on a hike and barely noticed the weight swinging around since the silicone grips my shoulder instead of sliding. The lanyard adjusts long enough to wear across my body under a jacket, which is exactly what I wanted for hands-free carrying. Solid coverage on the corners too.

The silicone has a nice soft-touch feel and the strap is thick enough that it doesn't dig into my shoulder. I wear it crossbody walking my dog and the adjustable lanyard actually stays where I set it.

The strap slides easily when I need to adjust it, but it occasionally loosens on its own during a long walk. The silicone feels grippy and the heavy-duty build gives me confidence it'll survive drops without adding too much bulk.
