PrimaLoft Silver provides great warmth for its weight.  It has a slightly lower warmth-to-weight ratio than PrimaLoft Gold and for this reason, is sometimes preferred for garments worn during more active pursuits.  It also does a good job of trapping body heat, maintaining breathability, and repelling water providing thermal insulation even when wet.  The fibers in PrimaLoft Silver are a little longer than in the Gold styles and therfore, can be quilted at a greater interval.   PrimaLoft recommends quilting the 100 gsm at an interval of 24 inches. 

Which PrimaLoft® Insulation Is Right for You?

Choose Gold when lightweight warmth and premium performance are the priority.
Choose Silver for an excellent balance of performance, durability, and value.
Choose Black for dependable everyday insulation at an economical price point.

All three insulation types share the core advantages that make synthetic insulation popular: warmth in wet conditions, easy care, fast drying, and reliable durability for active use.
