tarp and bivy Y-zip Bug Bivy | Ultralight Bivy

To get started

Included: Rigging (shock cord, tensionlocks, mitten hooks, and cord locks) is included with the bivy. See the Specs for exactly what the bivy comes with.

You'll want to attach rigging to the: top corners of the tub (4), apexes (2).

To determine the length of the cords: Lay the bivy under your pitched tarp. Then, measure the distance from the bivy's corner to the tarp's associated corner. Cut the shock cord to that length (the two front lengths should be equal, as should the two lengths at the foot).

Installing the rigging at the Apexes

Shock cord is used to suspend your bivy from your tarp's apexes or ridgeline. Using 20" (51cm) at the head end and 24" (61cm) at the foot is a good starting point for use with the 1P Cirriform.

• Note: You will do the following twice; once for each end of the net-tent.
• At one end of the shock cord, tie on a mitten hook. We suggest a clinch knot.
• Thread the cord through the webbing loop at the net-tent's apexes (front to back at the head end, and back to front at the foot end).
• Pass the cord through a cord lock.
• Tie a loop on the loose end of the cord. We suggest a simple overhand loop knot.
• Note: The images below show the 1P Bug Shelter, but the process is the same.

Installing rigging at the corners

Shock cord is used to connect the top corners of the tub to your tarp's corners. We recommend installing tensionlocks (10mm size) at the floor's corners for easy adjustment. For use with the 1P Cirriform, start with lengths of 36" (91cm) at the front corners and 30" (76cm) at the rear corners.

• Using a girth hitch, install a tensionlock on the upper tie-out loop at each of the tub's corners.
• Tie a mitten hook to the end of each cord. We like to use a clinch knot.
• Thread the untied end of the shockcord through the tensioner as shown (first through the middle opening from bottom to top, then through the remaining hole from top to bottom).
• Tie a loop in the untied end of the cord. We like like to use an overhand loop knot.
• Repeat at each corner
• Note: The images below show the 1P Bug Shelter, but the process is the same.

If you want to pitch the Bug Shelter by itself (without a tarp), there are two approaches:

1. With additional guyline: You'll need six stakes, your poles and additional guyline for the apexes. See guyline options here.
2. Stand alone rigging kit: With our stand alone rigging kit, the Bivy pitches with four stakes and your poles.

The pitching guide linked at the top of the page provides instruction on each method.
