Do Your Research: Insulation Types

At KUIU, we offer two types of insulation -

QuixDown, which is made from Polish goose down and 3DeFX+ which is made from continuous synthetic fibers. Both insulation types have performance advantages that will keep you comfortable on the toughest hunts. When deciding what’s best for you, consider your level of activity and the weather conditions.



Stationary versus Active

Mid Layer and Outer Layer Insulation

The weather and conditions are the deciding factor on where you decide to layer your insulation. If it’s cold, dry, and clear, it’s suitable to wear it on the outside. If it’s cold and wet, layer insulation under your rain gear.

We offer two styles of fit among our insulating layers. A mid-layer fit is sized to fit close to your body with minimal layers underneath. An outer-layer fit is sized to fit over base layers and mid layer insulation. For example, if you’re a size large, these combos would layer well together:

Mid-Layer Insulation Layering Example:

Outer-Layer Insulation Layering Example:

If you’re planning on wearing a garment sized with a mid-layer fit over multiple layers or you prefer a roomy fit, consider sizing up one size.
