    Thinking of ordering a thru-hiker kit, not sure what thickness to get. I’ve used a MLD 38 degree, and want something warmer. Thanks!

    As Tucas the cottage UL gear maker from Spain has quilts in Apex 133, 167 and 200. He quotes the following on temps:

    “Temperature rating.
    Rating a quilt is a bit complicated, as many factors are involved. However, the comfort temperatures that we assign to these quilts based on field testing are:

    Insulation Rating
    APEX 133 +5 C
    APEX 167 0 C
    APEX 200 -5 C”

    see:

    And for example Ripstop by the roll quotes the following:

    “The ultimate temp rating of a quilt or apparel is subject to several variables, but as a rough guide, the following temperature ratings can be expected when using single-layers of Climashield® APEX insulation:

    2.5 oz – 50o F
    3.6 oz – 40o F
    5.0 oz – 30o F
    7.5 oz – 10o F”

    Hope that helps.
