Regulator® Insulation provides phenomenal compressibility, light weight warmth and moisture transport, whether used alone or as part of a layering system.

The lofted hollow-core fibers of Regulator Insulation conserve body heat while allowing body moisture to wick uninhibited during sweat-inducing activity. They’re also lightweight and highly compressible for packing – a boon when every inch of pack space counts.

These pieces may be worn alone in milder weather. When weather looms, they complement our Climbing, Skiing and Snowboarding shells and Performance Baselayer pieces.

Regulator Insulation comes in four weights: R4, R3, R2, and R1:

R4–WINDPROOF INSULATION
Stretchy, lightweight fleece for wind protection

R3–HIGH-PILE WARMTH
Fur-like fibers create heat-retaining loft

R2–MIDWEIGHT INSULATION
Fur-like fibers offer superior warmth and lightweight breathability

R1–CORE WARMTH
High/low grid fabric insulates and moves moisture off skin
