- Quallifil® is a high-loft insulation made by Invista that is an
alternative to down. Quallofil insulation is engineered to provide
the optimum balance of compactibility, warmth, and durability.
Its patented seven-hole fibers hold more air, providing superior
warmth and softness, without extra weight. Quallofil is machine
washable/dryable, and is nonallergenic. In high performance
outerwear Quallofil offers 25% more warmth when wet than
down, and it dries three times faster than down. Quallofil
