【Specifications】 Size: 26-62cm adjustable 【Material】 Nylon 【Color】 Black New, unused item -------------------------------------------------- [Chest Balance Stabilization Belt] This chest strap eliminates the gap between the shoulder straps and the chest, allowing the backpack to fit more snugly against your back, increasing stability and distributing the weight load on your shoulders, back, and waist evenly. It relieves fatigue in your shoulders and waist. You'll feel like a heavy backpack is lighter and can carry it with ease! Backpacks can hold a lot of items, so you tend to pack them full, right? Haven't you ever felt, "Oh, it's surprisingly heavy..." when you put it on? This chest strap allows you to secure the backpack tightly to your body, as if it has become a part of your body! By attaching it to your backpack, it prevents the shoulder straps from slipping off your shoulders and eliminates the need to hold them with your hands to prevent swaying, freeing up both hands and increasing freedom of movement and safety while walking. [Convenient and Easy-to-Use D-Ring Hook] The belt has a D-shaped ring, allowing you to hang small items for outdoor activities or travel, freeing up your hands and increasing walking stability. If you put items you want to use quickly, like sunglasses or a camera, into your backpack, it becomes really troublesome to take them out, doesn't it? In such cases, if you hang them on the D-ring hook, you can use them quickly when the cloudy sky suddenly clears up, or when you are faced with a breathtaking view that might make you exclaim. [Easy to Attach] Suitable for adults and children. With a one-touch detachable buckle and adjustable features, it's easy to put on and take off, so even elementary school students can use it. Durable, non-stretching material. The band is intentionally designed not to stretch even when pulled. Unlike other products that use elastic material, this design improves the issue of the elastic stretching and contracting while walking, compromising the snug fit. There is no lifespan for the elastic, so you can use it for a long time.
