Savotta sternum strap. Nothing fancy, just a decent 25 mm wide sternum strap with a side-release buckle. Easy to attach almost anywhere, easy to open, easy to close, easy to adjust. Why no elastic section? Because those really dont do much good, when you tighten the sternum strap you stretch out the elastic and thats it then, it wont strech any more. Also those tend to wear out pretty fast, losing any elasticity they could have. Why not just 20 mm wide? Because a 25 mm side-release buckle is considerably easier to use, especially with thick winter gloves on. Why not a split-bar slider buckle for attachment? This low-tech system can be used with pretty much any shoulder strap, universal! Note.  Savotta manufactures this product in Finland and Estonia. Country of manufacture is labeled to the product. Fits virtually any sort of backpack shoulder straps Quick and easy to use side-release buckle Weight 45g Dimensions Max length: 50 cm Materials 100% polyester
