Down Insulation
Down not only has a soft, comfortable feel, it has the best warmth-to weight ratio of any insulation available. Down is known for its unmatched thermal efficiency, its high compressibility, and its durability. The one limitation of down is that it loses much of its ability to maintain warmth when it gets wet.
650 Fill power
650-fill power refers to the loft or `fluffiness` of insulation per unit of weight. The higher the fill power, the higher the loft and insulating value of the down. Specifically, fill power is the space that one ounce of down occupies in cubic inches. The fill power of down used in sleeping bags generally ranges from 500 to 850. Kelty uses 650 fill power down for its strong balance of performance and value.
Slant-baffle construction
Slant baffles use angled tricot walls to create overlapping baffles of down that protect against cold air making its way through the insulation. This construction method creates rhombus-shaped baffles that ensure even insulation coverage and prevent cold spots from forming. Used on colder-weather bags.
Chevron Shaped Baffles
Since down can shift within an individual baffle, we use chevron shaped baffles to limit this movement. The up-and-down chevron shape creates an obstacle to limit any unwanted side-to-side shifting of the down. These shapes are applied to slant, straight-wall, and sewn-through baffle construction in our down bag line.
