Description
This Bug Bivy features our unique "Y-zip" to allow entry from the front, side, diagonal, or above.
The width and height taper for efficiency, and the tub helps provide extra splash protection. Offered in two sizes and two lengths* to help dial in your setup.
- Y-zip offers multiple entry options
- Tapered shape for efficiency
- Slightly curved ridge to reduce slack
- Tub-floor provides extra splash protection.
- Rigging for connecting the bivy to a tarp is included.
New fabric option - The floor is now available in a 20D Ripstop Polyester with a Sil/PU coating. The PU coating on the inner face significantly improves puncture resistance and reduces slipperiness over the lighter 20D silpoly option (Sil/Sil coating) and our previously available 40D fabric.
Available in two lengths - The longer option provides an additional 6" (15cm) of length at the foot end. Please note that the additional length does not affect head or elbow room. The longer Bug Bivy will work with either length of our Cirriform Tarp, but will pair a little better with the longer Cirriform.
The bivy is best used under a-frame style tarps with the points above the head and foot suspended off of you. Create a tub-floor by clipping the top corners of the floor to your tarp. If you prefer to keep things simpler, just let the bivy drape over you and suspend the front apex to keep the netting off of your face.

Set-up & use
Download our here.
The tub-floor is intended to be suspended from its top corners by clipping them out to your tarp's corners using the included rigging. Suspend the upper off or your face and feet by clipping it to points above. For recommendations on how to install the rigging, please see the "Rigging" tab.
You may wish to the corners of the tub-floor. It shouldn't be necessary for most situations, but may be helpful should you find water pooling on the ground around you.
For simpler set-up when pitched without a tarp, consider using the which allows the bivy to be pitch with only 4 stakes and your poles. For more information, please see the link.
Rigging
To get started
Included: Rigging (shock cord, 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 6 to 7 locations on the bivy: top corners of the tub (4), apexes (2), middle of ridge (1)(optional on Ridge & Y-zip).
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).
To install the cords:
You don’t need to follow our method, but this is how we like to do it.
At the corners
- Tie a loop on one end of the shock cord. We like to use a simple overhand loop knot.
- Using a clinch knot, tie on a mitten hook to the other end of the cord.
- Attach the loop end of the cord to the tub's upper tie-outs with a girth hitch.
At the apexes
- Tie a loop on one end of the shock cord using an overhand loop knot.
- Pass the free end of the cord through a cord lock.
- Pass the free end of the cord through the small webbing loop at the apex.
- Using a clinch knot, tie on a mitten hook to the free end of the cord.
- NOTE: On the Ridge & Y-zip, webbing loops are found on both sides of the zipper at the front apex. Pass the cord through the loop on the side opposite the side you'd like to bivy to open towards.
Optional on the Ridge and Y-zip bivys
- Repeat the process used for the apex lines at the middle of the bivy's ridge.
Stand-alone rigging kit:
For pitching the bivy on its own, we also offer a . This lightweight kit allows you to pitch the bivy with your poles and just four stakes. Please see the for more information and instructions.
