Open it completely and you have a flat quilt for a muggy summer night at low elevation; close it up and you have a full mummy bag holding heat at 30F or 15F depending on the model. That range is the whole point of the Circuit, and it is why one bag can cover most of a Colorado season.\u003c\/p\u003e\u003cp\u003eFill is 650-plus fillpower Ultra-Dry Duck Down, treated so it keeps loft when the air in the tent gets damp. The shell is a 20D polyester that breathes well enough to move moisture out overnight and still holds up to repeated stuffing, and the bag compresses into the included compression sack. Inside, a brushed liner gives you room to move without dragging cold fabric across your skin.\u003c\/p\u003e\u003ch3\u003eKey features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eComfort in all conditions: opens flat for airflow on warm nights or zips closed to lock in warmth when temperatures drop\u003c\/li\u003e\n\u003cli\u003eEfficient packability: quality 650+ fillpower Ultra-Dry Duck Down and lightweight fabrics allow the Circuit to pack down small into the supplied compression sack\u003c\/li\u003e\n\u003cli\u003eRoom to move: comfort-oriented, brushed liner maximizes movement and maintains warmth all night\u003c\/li\u003e\n\u003cli\u003ePrecise ventilation: wrap-around zip lets you fully open the footbox for maximum venting and fine-tune airflow to regulate temperature\u003c\/li\u003e\n\u003cli\u003eLightweight breathability: featherlight 20D polyester balances airflow for moisture management with proven durability for long-term use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFill\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e650+ fillpower Ultra-Dry Duck Down\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTemperature ratings\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e-1C \/ 30F and -9C \/ 15F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eShell fabric\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e20D polyester\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eLiner\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBrushed, comfort-oriented\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eZipper\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eWrap-around, fully opening footbox\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePacking\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCompression sack included\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eLengths\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eShort, Regular, Long\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eColorway\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDark Blue\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003eCome see it at 432 E Main St in downtown Montrose, Colorado, or order online.
