{"product_id":"garmin-index-sleep-monitor","title":"Garmin Index Sleep Monitor Armband","description":"\u003cp\u003eThe Index Sleep Monitor is worn on the upper arm rather than the wrist, which is the point of it: a soft nylon and spandex band is less intrusive to sleep in than a watch, and an upper-arm position produces steadier overnight readings than a wrist that moves under a pillow.\u003c\/p\u003e\u003cp\u003eIt records sleep stages, heart rate, heart rate variability, pulse ox and respiration, and feeds them into Garmin Connect alongside your training data — so recovery, sleep score and body battery reflect a night measured properly rather than inferred.\u003c\/p\u003e\u003cp\u003eThe band is 70% nylon and 30% spandex, breathable and stretchy, and the module weighs 14.5 g. Battery runs about seven nights with pulse ox enabled on typical eight-hour nights, and the unit carries a 5 ATM water rating. Choose S\/M or L\/XL to match your upper arm.\u003c\/p\u003e","brand":"Garmin","offers":[{"title":"S\/M","offer_id":48499970113757,"sku":"010-03024-01","price":169.99,"currency_code":"USD","in_stock":false},{"title":"L\/XL","offer_id":48499970146525,"sku":"010-03024-00","price":169.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0065\/3810\/0851\/files\/cf-xl_f806461e-0e87-481f-ab89-61228229b8ff.jpg?v=1788476098","url":"https:\/\/divecatalog.com\/products\/garmin-index-sleep-monitor","provider":"DiveCatalog.com","version":"1.0","type":"link"}
