Every stitch line is a place where the insulation is squeezed to nothing and the cold comes through. We build two independent layers and stagger the seams of the second between the seams of the first, so no stitch line passes straight through the bag. There is no cold seam anywhere in it.\u003c\/p\u003e\n\n\u003ch3\u003eAbout the rating\u003c\/h3\u003e\n\u003cp\u003eThere is no mandatory temperature standard below −4°F, so anyone can print any number on a label. We would rather show our work. −40°F is a construction specification derived from our published loading and loft, benchmarked against our Montana −30. Compare the numbers above against anything else on the market.\u003c\/p\u003e\n\n\u003cp style=\"font-size:14px;color:#6b655c;\"\u003e\u003cem\u003eCurrently in production.
