Heavy Insulation (Layer 4) A hooded down or synthetic jacket. Go-To Layer This layering piece becomes the go-to for most guides on Denali. It spans the gap between a typical insulating layer and a down parka. As a result, they are worn more often than not around camp and climbing on cold mornings before the sun hits. Additionally, it is a great supplemental insulation piece to wear in combination with your other layers. Hard Shell (Layer 5) A jacket made of rain-proof material with an attached hood. We recommend a non-insulated jacket for this layer. What to Look for in a Hard Shell The hard shell jacket should be made of a water proof, nylon material (such as Gore-Tex®). A thinner and lighter weight jacket is ample, and ideal for the climb. It should have an attached hood for protection from the elements.
