Cross Mountain 40 Degree Synthetic


Cross Mountain 40 Degree Synthetic

from 134.95

The Cross Mountain is a 40-degree, synthetically-insulated, rectangular sleeping bag.  Great value; high quality.  Insulated with Insotect Hotstream® insulation, featuring 100% recycled material, which feels as warm and soft as down insulation. 

The Cross Mountain is a mild-to-warm weather bag, minimally insulated.  Rated for 40 degrees Fahrenheit, but that's more a survival rating than a comfort rating.  A 40 degree bag isn't going to be comfortable if the mercury drops to 40 degrees.  Always get a bag rated for 15-20 degrees lower than the lowest temp you're ever likely to use it in.  The Cross Mountain is a great overbag to use in combination with a 30 or 15 degree bag.
