Description

Simple, fully enclosed insect protection with a tub-floor and wind-resistant upper.

The Wind Bivy features our unique "Y-zip" to allow entry from the front, side, diagonal, or above. It's a great for use during cooler weather, as well as in locations with blowing sand. The woven, wind resistant upper provides high breathability and good transparency, with additional splash protection.

  • "Y" Zipper provides entry from the front, top, or either side
  • Upper material maintains visibility to the outside world
  • Highly breathable, yet wind resistant upper
  • Vented apex
  • DWR treated, splash resistant upper
  • Silpoly Tub-floor

Note that since the upper restricts airflow, it will retain some warmth and may become stuffy in warmer, humid weather. We've added venting to the apex, to reduce this, but in such environments, our Bug Bivy would be a better choice.

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, maybe suspending the front apex to keep the fabric off of your face.

*When paired with our Cirriform tarp, the longer option will fit under the Regular Length 1P Cirriform Tarp.

Made in the USA from imported materials.

Set-up & use

Download our PDF pitching guide 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 seam seal 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 Stand-alone rigging kit 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

  1. Tie a loop on one end of the shock cord. We like to use a simple overhand loop knot.
  2. Using a clinch knot, tie on a mitten hook to the other end of the cord.
  3. Attach the loop end of the cord to the tub with a girth hitch.

At the apexes

  1. Tie a loop on one end of the shock cord using an overhand loop knot.
  2. Pass the free end of the cord through a cord lock.
  3. Pass the free end of the cord through the small webbing loop at the apex.
  4. Using a clinch knot, tie on a mitten hook to the free end of the cord.
  5. 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

  1. 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 stand-alone rigging kit. This lightweight kit allows you to pitch the bivy with your poles and just four stakes. Please see the rigging kit's page for more information and instructions.

The best programming book you will ever read
Format: Paperback
This is without a doubt the best introduction to any programming language you will find. This book takes a hands on approach to learning Python. Concepts are explained clearly and examples and counter-examples are littered throughout each chapters. I like the direct/no waste time with useless preamble approach to explaining key concepts. The explanations are as succinct as it can get. The writer give general advice like not making your solution too generic initially but focus on solving the problem at hand first and then make the code more elaborate. The writer give off a patient tone as he encourages the reader to not be too hard on themselves when they make mistakes but view this as part of the learning process. He gives his own experience and also that of other programmers to encourage the reader to realistically evaluate their circumstances. What I like most about this book is that the exercises are intersperced between the sections within the chapters. That way you get to practice just after learning a new concept. There are final exercises incorporating what was covered in the chapter, the they do not seem to be a summary of all the content. I am reviewing now 23/02/2025. I have read the first 9 chapters and i am currently on chapter 10. When I am done i will update this review. I use Jupter Notebooks to complete exercises. I head the first cell with the problem number and title and set it as a mark-down cell so it heads that mini section and the code window below contains my solution. That way I have all exercises for a chapter in one file and can easily scroll up to see previous solutions and copy code which the problems requests at times. In the end I envisage I will have 20 files - one per chapter.

Great book!
Format: Paperback
Great book! I really like how the instructions are explained in the book and how it encourages you to both use the terminal / python interpreter and make files in vscode. This book can be used for intermediate python programmers and brand new programs. for the intermediate people, its a good refresher of the basics, and by the end you will definitely KNOW, KNOW them. I got this book in prep for new grad job applications, code assessments, game jams, and general practice. So I think you would do good to get this book at any level if you really want to get the basics down and know them!

One of the best Python books
Format: Paperback
I bought 5 Python books as I needed to learn the language quickly for an upcoming project. Of all the books that I purchased, I found this one to be the best. It starts out with the basics and works its way through more complicated areas. Each chapter builds well upon the other. There is very little redundancy, and I was able to get through the book in about a week. I have a background in software development, so this book was able to show me how Python implements different concepts that I already knew, but I think a beginner would also be comfortable with the material.
