A PrimaLoft buyer’s guide from Rock/Creek

What is PrimaLoft? PrimaLoft is a synthetic insulation used in high-end outerwear and accessories, particularly those intended for use in damp conditions (where natural goose down loses its insulative property). This ability to maintain effectiveness, even when wet, makes PrimaLoft-insulated gear incredibly versatile for snowsports, travel, or anywhere you need lightweight warmth that won’t fail when things get ugly!

Compared to other types of synthetic insulation, PrimaLoft uses an ultra-fine material for maximum warmth, compressibility and the softest feel possible. Its fibers repel water more effectively than competing products, ensuring maximum performance in nasty, wet conditions. Simply put, PrimaLoft is warmer, drier and softer than other synthetic insulations. It’s considered the best synthetic insulation in the world.

PrimaLoft is a sponsor of the Rock/Creek StumpJump 50k, and in celebration of the race they’re giving away two jackets! To enter to win a new PrimaLoft jacket — The North Face Anamagi Jacket for women, The North Face Redpoint Jacket for men — visit our Facebook wall and post a photo of your ratty, old, worn-out running jacket! The most “overtrained” jackets will be chosen as winners.
