What makes this bag line so special?

Our Advanced Synthetic insulation is engineered to be:
  • High Loft
  • Water Resistant
  • Breathable
  • Packable
  • Lightweight
  • Durable
Moreover, when tested for warmth, our Advanced Synthetic tested WARMER than 600 Fill Power Goose Down!

Normally, synthetic insulation tests to be 300 - 400 Fill Power while our innovative, engineered Advanced Synthetic tested to have a loft equivalent to 625 Fill Power.

This means that our Advanced Synthetic insulation boasts a higher warmth-to-weight ratio than other synthetics.  To top it off, it's more compressible and durable too!


The secret sauce with these bags is that they are filled with an Advanced Synthetic that has tested to be 625 Fill Power and has been called “the closest synthetic insulation to natural down ever developed" by the Outdoor Industry Association.
