J91 is J58's bigger bad brother. Sharing the same modular, lightweight, exceedingly comfortable DNA, but cut to fit over a broader section of layers and body shapes. The outstanding properties of PrimaLoft® insulation and WINDSTOPPER® shell make it formidable as both a component piece* or a jacket on its own. Category defining modular insulation and lots of zippers.
PrimaLoft® insulation is designed to regulate comfort levels during intense activity while offering uncompromising performance in all conditions. Combined with 2-layer Gore Windstopper®, the results are incredibly soft, warm, light, and protective. Effortless and effective.
*Specifically designed to layer underneath WIDE fit shells but can compress down to be worn under STRAIGHT fit shells. Can also be worn over top of PROFILE fit items
