One of the topics I’m exploring in 2020 is fastpacking, and Goosefeet Gear agreed to take on the challenge of making an insulated top that pushed the limits of warmth while maintaining a weight that was as low as possible. Therein lies the motivation behind this particular down-insulated sweater.

Here’s a brief video overview:

First Impressions

  • This sweater may be the warmest sub-6 oz (170) insulated garment I’ve ever worn.
  • I specified a generous back and sleeve length. I’m pleased about that! The generous sizing makes it a more comfortable garment, especially in cold conditions.
  • I specified a slim profile. So as long as I can keep the “Covid 15” away, I can layer this under my rain shell if needed!
  • Packed size is tiny, which is perhaps my favorite feature, especially in the context of fastpacking, where I’m using a small (30L) backpack.
  • I can fit the sweater easily into a 5 in x 8 in (13 cm x 20 cm) stuff sack, and it could almost certainly go into one a little smaller.
