Nylon Taslan Shell

Our Snap Jacks feature a lightweight Nylon Taslan shell. Air-textured yarn gives the fabric a durable outer-face and dull finish. The shoulder yoke features a burlier 80-denier shell, while the body fabric is a 40-denier weave with supple, cotton-touch characteristics. The face and construction of these fabrics lends the garment a rugged, durable look, while the final product remains incredibly lightweight and packable.

Primaloft® Silver Insulation

Primaloft® Silver Insulation is the perfect combination of lightweight, packable loft and durability for the Snap Jack garments. Featuring Primaloft®’s signature water-repellency, pack-ability, and softness, the Silver Insulation brings some added durability for rugged outdoor endeavors.

Soft-Touch Lining

Our soft-touch nylon lining with a hydrophilic coating wicks moisture from your mid-layer, and dries quickly for increased comfort.
