3M™ Thinsulate™

The original warmth-without-bulk insulation, 3M™ Thinsulate™ Insulation is the brand trusted for warmth.

3M™ Thinsulate™ Insulation enhances your ability to enjoy the outdoors, providing:

  • Breathable, lightweight warmth and durability
  • Up to nearly twice the warmth of other synthetics and one-and-a-half times the warmth of 550 fill down when equal thicknesses are measured
  • Highly breathable, “keep dry comfort” under damp, sweaty or rainy conditions
  • The freedom of movement to enjoy your time outdoors with less restriction
  • Dependable thermal performance through repeated washings

Why is 3M™ Thinsulate™ Insulation so efficient? It’s the fibers. The unique fiber constructions of 3M™ Thinsulate™ Insulation are up to 10x smaller than the fibers of other synthetic insulations,* which helps make them more effective at trapping insulating air. The more fibers it has per square inch, the better an insulation can perform in containing the body’s radiant heat.

*With the exception of 3M™ Thinsulate™ Platinum Insulation – FR

Exceptional performance even in wet conditions: The fibers in most 3M™ Thinsulate™ Insulation products absorb less than 1% by weight of water, and are designed to keep you warm even in damp conditions. No other synthetic insulation performs better to help prevent rain penetration/water absorption under real-world conditions. Superior insulating efficiency does not diminish breathability: 3M™ Thinsulate™ Insulation allows moisture the body creates to exit.
