Avid wool manufacturing engineers at L. W. Packard were looking for high quality, warm, and comfortable garments for outdoor activities. There was a gap from what was available - expensive high end goods to poorly made, low cost inferior constructed synthetic garments. Minus33 was started to fill the gap in the market.
New Hampshire, being home to some of the worlds worst weather, has been the playground and testing field for Minus33. They've found that nature has given mankind the best fiber in the world, Merino Wool, to equip everyone from the avid outdoor athlete to the devoted couch surfer.
