What is PrimaLoft®? The US Army commissioned PrimaLoft® to develop a synthetic fibre in the 1980s to create a blanket with the advantages of 'down', which at the same time compensates for its negatives when it comes to weight, versatility and ease to care for. Since then, PrimaLoft® has commonly been used for outdoor clothing, sleeping bags or gloves. The benefits of PrimaLoft® are: High breathability, very good moisture regulation, durable bulkiness & extreme compressibility |
