How to wash active insulation fabrics?

Active insulation provides breathable warmth against the cold. If the winter’s frigid temps don’t stop you from trail running, skiing, or hiking, active insulation is for you. Instead of exclusively locking in heat like a traditional puffer, active insulation helps move moisture from your body, making sure you’re not dripping with sweat during high exertion or freezing on your cool down.

To wash active insulation fabrics, use a gentle detergent designed for delicate fabrics or specifically for down or synthetic insulation. Wash on a gentle cycle with cold water, avoiding fabric softeners and bleach, which can affect insulation performance. Ensure you rinse thoroughly and dry properly, either by tumble drying on low heat or air drying.

Here's a more detailed breakdown:

Before Washing:

Turn the garment inside out: This helps protect the outer fabric and insulation from damage during the washing process.

Close zips and Velcro: This prevents them from snagging or getting damaged during the wash.

Loosen drawstrings and hook-and-loop fasteners: This allows for better cleaning and helps prevent them from getting tangled.

Washing:

Choose a gentle detergent: Opt for a detergent specifically for delicate fabrics, down, or synthetic insulation.

Use cold water: Cold water helps prevent shrinking and damage to the insulation.

Select a gentle wash cycle: Choose a cycle designed for delicate fabrics, wools, or handwash.

Rinse thoroughly: Ensure you rinse at least twice to remove all detergent residue, as this can hinder performance.

Avoid fabric softeners and bleach: These can negatively impact the insulation's performance.

Drying:

Tumble dry on low heat: Low heat helps maintain the insulation's loft and prevents damage.

Air dry flat: This is a good alternative if you prefer to avoid tumble drying.

Use tennis balls in the dryer (for down insulation): This helps fluff up the insulation and prevent clumping.
