Ultralight Bivy (chest zipper):


Our original bivy we've been selling since 2011.

Standard features:

- 1.3oz silpoly floor - waterproof and durable

- Water Resistant/Breathable upper fabric in either Argon67 or Argon90

- 0.7oz no-see-um netting top

- #3 YKK zipper across chest with two double sided pulls(if you want a side zipper, go here)

- 5.9 ounces for standard length, standard girth in Argon90

- 5.1 ounces for standard length, standard girth in Argon67

- Argon67 and 90 are ripstop DWR coated nylon fabrics. They both have excellent breathability. Both shed water nicely, with the 90 being slightly more water resistant than the 67.

- Grosgrain pull-loop to keep netting off face - includes shock cord

- Silnylon stuff sack included

- Made in Montana



Length: Standard fits users up to 6'1", Long fits users up to 6'4"

Width: Standard is 73" in girth at the shoulders, 64" at the feet. If the user is under 180lbs, use a regular width.

Wide is 78" at the shoulders and 68" at the feet. If the user is 180-220lbs, use a wide. If you use a 25" wide pad, go with a wide regardless of weight.

For users over 220lbs or 6'4", please contact us for custom sizing. Custom sizing is free in nearly all cases.

Each oversize option (long length, wide girth) adds about 0.3oz, so a long/wide would weigh ~0.6oz more
