【Smart App Control】 With our smartphone app, you control everything: switch between four precise temperatures (45°C to 70°C), set timers, and activate quick-heat mode—right from your jacket pocket. No more fumbling with buttons mid-hike.
【Four-Level Precise Heating】 Offers four temperature settings: Ultra-high setting (65–70°C/149–158°F) prioritizes maximum heat flow for 3.5 hours; High (55–60°C/131–140°F) provides sustained strong heat for 5 hours; Medium (50–55°C/122–131°F) balances output and efficiency over 6 hours; and Low (45°C/113°F) optimizes energy efficiency over 7 hours—each setting can be adjusted to provide warmth under different operating conditions.
【Durable 3000mAh Dual Batteries】 Two integrated 3000mAh batteries deliver verified endurance—7 hours of continuous gentle heat on low mode. Trust them through back-to-back ski runs, fishing dawn till dusk, or double shifts at the frosty warehouse.
【Breathable, Comfortable Design】 Ergonomic construction with elastic textiles ensures continuous comfort during motion. Skin-contact layers employ non-irritating materials for sustained wearability.
【Easy Machine Wash】 Remove batteries, machine-wash gently, and air-dry. They'll handle 50+ cycles—season after season—without losing warmth or shape. Invest once; toast winters for years.
