The Winter Nest hangs freely below the hammock shell, keeping the down fully lofted between you and the cold air all night — no pads to shift, no air gaps to open, no waking up cold at 2 a.m. The split entrance with non-snagging mixed hook-and-loop closure attaches directly to the Hennessy's existing entrance hook and loop, retaining full bottom-entry access without modification or hardware. Setup takes under a minute. The Winter Nest is designed for bottom-entry Hennessy Hammocks only — if you have a side-entry or zip-entry Hennessy, the \u003ca href=\"\/products\/mt-washington-4-0-degree-winter-hammock-underquilt\"\u003eMt Washington 4\u003c\/a\u003e is the right underquilt.\u003c\/p\u003e\n\n\u003ch2\u003eHow It's Built: Box Baffles, 850 Fill Power Down, 1.1 oz Taffeta Shell\u003c\/h2\u003e\n\n\u003cp\u003eThe Winter Nest uses box baffle construction — sealed chambers that keep the down evenly distributed and fully lofted across the full length of the underquilt. At 0°F, an uneven loft distribution creates cold spots that can't be recovered mid-night. The improved foot-end drawcord modification pulls the underquilt close at the legs to eliminate the dead air pocket under the feet.\u003c\/p\u003e\n\n\u003cp\u003eThe Winter Nest is filled with 850 Fill Power RDS-certified down. Fill power measures how many cubic inches of loft one ounce of down produces when fully expanded — at 850FP, the Winter Nest achieves its 0°F rating with less fill by weight than underquilts built with lower-grade down. Every Winter Nest ships with a 33% overstuff by weight, so it holds its rating even as the down accumulates oils and dirt between cleanings and loses loft.\u003c\/p\u003e\n\n\u003cp\u003eSuspension is via the JRB Suspension System, included with the underquilt. The improved foot-end drawcord pulls tight at the legs for a complete seal on the coldest nights. No sewing, no special hardware, no modification to the hammock.\u003c\/p\u003e\n\n\u003cp\u003eThe shell is 1.1 oz taffeta with a DWR coating. Every Winter Nest ships in a storage bag that does not compress the down — keep the quilt in it between trips for long-term loft preservation.\u003c\/p\u003e\n\n\u003ch2\u003eHow the Nest Got Its Name\u003c\/h2\u003e\n\n\u003cp\u003eIn May 2004, Jacks R Better introduced the first commercially available underquilt for the Hennessy Hammock. There was no product like it. Hennessy campers had been wrestling with pads and improvised solutions, waking up cold, and making do. The underquilt changed that — hung below the hammock, fully lofted, sealed at the ends, it turned a hammock into a warm, enclosed sleeping system. The name came naturally: you were no longer just hanging in a hammock. You were nested.\u003c\/p\u003e\n\n\u003cp\u003eThe Winter Nest takes that same design into 0°F territory — for Hennessy hammock campers who don't stop when the temperature drops.\u003c\/p\u003e\n\n\u003cp\u003eHandmade in Pennsylvania by Jacks R Better — making quilts since 2004. In-stock quilts ship the same or next business day.\u003c\/p\u003e\n\n\u003ch2\u003eSpecs: Winter Nest 0°F Hennessy Hammock Underquilt\u003c\/h2\u003e\n\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpec\u003c\/th\u003e\n\u003cth\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperature Rating\u003c\/td\u003e\n\u003ctd\u003e0°F (-17°C) comfort\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFill Power\u003c\/td\u003e\n\u003ctd\u003e850FP RDS-certified down\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength\u003c\/td\u003e\n\u003ctd\u003e77 in (1.96 m)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e48 in (1.22 m)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e29 oz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShell\u003c\/td\u003e\n\u003ctd\u003e1.1 oz taffeta with DWR coating\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003eBox Baffles\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSuspension\u003c\/td\u003e\n\u003ctd\u003eJRB Suspension System included\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatibility\u003c\/td\u003e\n\u003ctd\u003eBottom-entry Hennessy Hammocks only\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003cp\u003e\u003cem\u003eFor side-entry or zip-entry Hennessy Hammocks, see the \u003ca href=\"\/products\/mt-washington-4-0-degree-winter-hammock-underquilt\"\u003eMt Washington 4\u003c\/a\u003e.
