You’re not getting older: You’re evolving! And so is Marmot’s venerable PreCip® waterproofing technology. Seam-taped and equipped with secure closures and a double storm flap over the main zipper, the Storm Shield is impervious to the wet, and incredibly comfortable to wear—with comfy mesh and taffeta-lined hand warmer pockets.
PreCip® is Marmot's proprietary PU (polyurethane) coating technology, specially engineered for unlined garments. It combines a hydrophobic and hydrophilic PU with our special Dry Touch Technology to create a very precisely controlled 2.5 layer coating system.
Dry Touch incorporates ceramic particles in the surface of the coating reducing condensation and the sticky clammy feel of most coatings.
The key to PreCip® is its barrier technology: a microporous polyurethane that is permeated with silicon dioxide particles. These particles create small, numerous, very consistent airways that keep the rain out while releasing body moisture to keep you dry inside and out.
PreCip® is not only waterproof, windproof, breathable and comfortable, but compressible enough to travel with you wherever the road leads.
