Big Agnes System Bags easily attach to a sleeping pad allowing you to comfortably roll around inside without rolling off your pad. The top panel of the bag creates a unique draping effect that feels more like the comforter on your bed at home. The insulation on the bottom of the bag is unnecessary in this system, so you won’t find any there, since heat is reflected from the sleeping pad back into the bag, you’ll want to make sure to add a pad to your cart!

What’s in a Name?

Frank Sandhofer had his eggs in many baskets: He owned houses in Hahns Peak Village, was a vegetable farmer, and struck gold ore in the area in 1908. The Sandhofer Houses became prime real estate in the area, as the corresponding Sandhofer Ditch provided ample irrigation for farming. One of the houses was turned into the post office for many years.
