{"product_id":"bastion","title":"Bastion 10°F Sleeping Bag","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eMost sleeping bags trap the moisture your body gives off, leaving you cold and clammy by morning. The Bastion does the opposite. Made with proprietary Keloflex™, it pulls breath, sweat, and condensation away, so you stay dry and your temperature holds steady all night.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eIt's also the most adaptable bag we've built.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eOne bag, or two.\u003c\/strong\u003e Sleeping solo? Slide one foot pocket into the other for double the insulation underfoot, because no one sleeps well with cold feet. Sleeping out with a partner? Slide the foot pockets of one Bastion into a GameChanger or a second Bastion, and the two combine into a full two-person system. No zippers, no fuss.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eHead-in warmth that doesn't fight you.\u003c\/strong\u003e Tuck fully inside for true head-to-toe heat. In an ordinary bag, breathing inside dampens the insulation and saps its warmth. Keloflex™ pushes that breath moisture out instead, so tucking in keeps you warm.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eWhat you wear matters.\u003c\/strong\u003e The Bastion keeps you dry by pulling moisture off your body and out of the bag, so what you sleep in either helps or fights it. Cotton is the biggest culprit: it soaks up moisture and holds it against your skin, and spandex has a cooling effect, which is counterproductive. Sleep in synthetic or merino wool base layers instead, and keep cotton and spandex out of the bag. It's a small choice that makes a big difference in how comfortable the whole system keeps you.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eWhat matters:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eDual foot pockets.\u003c\/strong\u003e Double the insulation underfoot when solo, or join two bags into a two-person system.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eHead-in heat retention.\u003c\/strong\u003e Tuck fully inside for head-to-toe warmth without the cold, damp breath problem of ordinary bags.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eMoisture managed, not trapped.\u003c\/strong\u003e Keloflex™ moves breath, sweat, and condensation away so your insulation stays dry.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eRated to 10°F (-12°C).\u003c\/strong\u003e Built for serious cold-weather and preparedness use.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eSteady overnight comfort.\u003c\/strong\u003e Regulates body heat as outdoor conditions shift.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eNo zippers.\u003c\/strong\u003e A cleaner, more durable design with nothing to snag, jam, or fail.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eBuilt with proprietary Keloflex™.\u003c\/strong\u003e Engineered for next-generation performance.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eMade to last.\u003c\/strong\u003e Durable enough to perform season after season.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e100% Risk-Free Satisfaction Guarantee.\u003c\/strong\u003e Try it with nothing to lose.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"k3core","offers":[{"title":"Medium fits up to 5' 8\" (68\")","offer_id":45316990435362,"sku":null,"price":549.0,"currency_code":"USD","in_stock":true},{"title":"Large fits up to 6' 1\" (74\")","offer_id":44834614083618,"sku":null,"price":599.0,"currency_code":"USD","in_stock":true},{"title":"Extra Tall fits up to 6' 8\" (80\")","offer_id":44834614116386,"sku":null,"price":649.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0841\/6067\/5874\/files\/Sleeping_Bag1_3820c51e-eba5-4eba-b957-18bfe72bc2d5.png?v=1783547239","url":"https:\/\/k3core.com\/products\/bastion","provider":"k3core","version":"1.0","type":"link"}
