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:
- Merino 145 Zip-T | Fit: Base-Layer, Size: Large
- Kenai Jacket Fit: Mid-Layer, Size: Large
- KUIU Kutana Storm Shell Jacket | Fit: Outer-Layer, Size: Large
OUTER-LAYER INSULATION LAYERING EXAMPLE:
- Merino 145 Zip-T | Fit: Base-Layer, Size: Large
- StrongFleece 235 Hoodie | Fit: Mid-Layer, Size: Large
- Kenai Vest | Fit: Mid-Layer, Size: Large
- Super Down PRO Hooded Jacket | Fit: Outer-Layer, Size: Large
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.
