{"product_id":"the-windward-800fp-down-sleeping-bag","title":"The Windward | 800 Fill Power Ultralight Down Sleeping Bag","description":"\u003cdiv class=\"product-narrative\"\u003e\n\u003cp\u003e\u003cstrong\u003eCold is honest. It finds every gap in your kit.\u003c\/strong\u003e A sleeping bag cannot bluff its way through a sub-zero night. Either the fill loft recovers after compression, or you spend the night chasing warmth you already lost. The Windward carries 800 fill power down - the grade where warmth stops being a function of bulk and starts being a function of quality - inside a nylon iFlex shell finished with a durable water repellent treatment, so a damp tent floor is no longer a sentence.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWarmth should be adjustable, not fixed.\u003c\/strong\u003e Most bags hand you one answer. This one is built around adjustment: an insulated draft tube you cinch around your neck to lock warm air in, a trapezoidal foot box that keeps your feet in a shape they can actually occupy, and pad cords that hold the bag centred on your sleeping pad all night. The mummy cut gives you the snug envelope of an alpine bag, but the geometry is tuned so you can vent when you are warm instead of waking to unzip a decision you made hours earlier.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eComfort range 0 to minus 10 degrees Celsius. Packed weight you can carry without negotiating.\u003c\/strong\u003e Two sizes cover most adult sleepers: 176 x 130 cm for standard builds and 196 x 140 cm for taller frames and side sleepers who need shoulder room. It ships with a compression stuff sack for the trail and a loose mesh bag for breathable storage at home, which is how down survives a decade instead of three seasons.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eWarmth is not a number on a specification sheet.

Backpackers and bikepackers use it because 800 fill power down is the only way to carry a true winter rating at a volume that still fits a 40 litre pack. Mountaineers use it in huts and snow caves where the difference between a 0 C and a minus 5 C rating decides whether the next day happens. Car campers use it as the one piece of gear worth upgrading first, because a bad bag ruins every trip regardless of how good the rest of the kit is. It also solves the awkward middle - the shoulder-season trips where a summer bag leaves you cold at 4 a.m. and an expedition bag makes you sweat before midnight.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product-faq\"\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cdiv style=\"margin-bottom: 16px;\"\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What does 800 fill power actually mean?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFill power measures how much volume one ounce of down occupies. At 800, a given weight of down traps more air than 600 or 700 fill, so the same warmth fits in a smaller, lighter package. It is the metric that separates a bag you carry from a bag you tolerate.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 16px;\"\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What temperature range is this bag rated for?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe stated comfort range is 0 C to minus 10 C. Read it as a comfort rating for a dressed adult sleeper, not a survival limit.

Down outperforms synthetic insulation on warmth per gram and on longevity, provided it is stored uncompressed, which is why a mesh storage sack is included alongside the stuff sack.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 16px;\"\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Will it fit me?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eTwo sizes are available.
