The technical camping blanket space has gotten incredibly competitive as of late, but this one wearable.
The Honcho Poncho is a 75” x 57” camping blanket that transforms into a drawstring poncho with front zipper pocket and kangaroo hand pockets. The synthetic 37.5 insulation will keep you warm and dry, and by definition the Poncho is very breathable. Because you’re wearing a blanket rather than a potentially restrictive outer layer, you’ll also have full range of movement.
As an added bonus, the Honcho Poncho stuffs down into its own front pocket for portability.
