{"type":"firestarter.listing","listing":{"id":"lst_-NIm8XRB","product_name":"Training Sternum Strap","category":"Gear Accessories","description":"Adjustable Weight Distribution\nWhen you hear that click sound, that means it's getting serious. Engage your sternum strap to disperse heavy loads and help transfer the weight forward on your body while rucking.\nKeeps your rucksack secure without constricting breath or movement and is adjustable by the MOLLE on the straps. Example: While doing burpees, you may want it a little tighter. While on the move, a little looser. Easy adjustment, on the fly.\nWhile rucks are made to be worn high on the back, Training Sternum Straps can provide reduced jarring and tumbling of your rucksack. Adding a Training Sternum Strap can also change the way weight is dispersed across your chest and shoulders. This added line across the body allows for a quick carabiner clip-in point, too.\nRemovable and adjustable, Training Sternum Straps attach via clasps to the MOLLE webbing on the shoulder straps of a rucksack for additional stabilization.","images":["https://cdn.shopify.com/s/files/1/0275/4985/9940/products/new-training-sternum-strap-2.jpg?v=1767719328","https://cdn.shopify.com/s/files/1/0275/4985/9940/files/sternum_black_04392a54-d68f-4685-a4e8-f0199f03d020.jpg?v=1767719329","https://cdn.shopify.com/s/files/1/0275/4985/9940/products/new-training-sternum-strap-4.jpg?v=1767719331","https://cdn.shopify.com/s/files/1/0275/4985/9940/products/new-training-sternum-strap-6.jpg?v=1767719332","https://cdn.shopify.com/s/files/1/0275/4985/9940/products/new-training-sternum-strap-1.jpg?v=1767719334","https://cdn.shopify.com/s/files/1/0275/4985/9940/products/new-training-sternum-strap-5.jpg?v=1767719336","https://cdn.shopify.com/s/files/1/0275/4985/9940/products/Rucking_Kit__GR2_UnnamedVariant_4_1040x693_P230_PV785_1__16872.1561817581.1280.1280.jpg?v=1767719337","https://cdn.shopify.com/s/files/1/0275/4985/9940/files/SternumStrap_ArmorGrey_Sku-ST-0505.jpg?v=1767719340","https://cdn.shopify.com/s/files/1/0275/4985/9940/files/Sternum-Strap-_Armor-Grey__2.jpg?v=1767719342","https://cdn.shopify.com/s/files/1/0275/4985/9940/files/Sternum-Strap-_Armor-Grey__1.jpg?v=1767719344","https://cdn.shopify.com/s/files/1/0275/4985/9940/files/Sternum-Strap-_Armor-Grey__3.jpg?v=1767719347","https://cdn.shopify.com/s/files/1/0275/4985/9940/files/training_sternum_ranger_a178f08d-6780-4aa8-908e-47750489d76b.jpg?v=1769528121","https://cdn.shopify.com/s/files/1/0275/4985/9940/files/ranger_sternum2_86cac6f7-b91e-42b9-915b-1cd8d41a49f1.jpg?v=1769528104","https://cdn.shopify.com/s/files/1/0275/4985/9940/files/2025_08_01-SRT90.jpg?v=1776369064","https://cdn.shopify.com/s/files/1/0275/4985/9940/files/CopyofSternumStrap_Coyote_0_1040x693_P137_PV399.jpg?v=1776951519","https://cdn.shopify.com/s/files/1/0275/4985/9940/files/2025_08_01-SRT107.jpg?v=1776369064"],"price":10,"currency":"USD","in_stock":true,"inventory_qty":39996,"dynamic_pricing":false,"listed_at":"2026-06-20T14:56:00.108Z"},"share_url":"https://firestarter.network/l/lst_-NIm8XRB","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
