Tent Rainfly Modification




Introduction: Tent Rainfly Modification

The purpose of this Instructable is 3 fold.

1) Improve air circulation and help remove condensation buildup inside the tent. As well as keep any condensation that does form away from your head/feet.

2) Add stability to the tent in high wind environments

3) Help shed rain away from the base of the tent.

This is accomplished by pulling the front and back of the rainfly away from the base of the tent.

Step 1: The Improvment

The first picture shows the tent as usual. Don't get me wrong, this tent is the best I've ever owned, but there is always room to improve. The grey panels are the doors (sides) and the green panel is the front/back. It is the green panel that we are modifying. It will be pulled out via guy line to keep it taught and allow for air to flow into the tent.

Step 2: Measure It Out!

The first step is to find the center point of the rainfly panel you want to guy out. In my case, the panel was 71" long, so I marked 35.5" (half way). We are applying the glue and loop to the underside of the rainfly panel, so be sure you have it oriented correctly.

Step 3: The Materials

Essentially, what we are doing is adding an attachment point to the front & back panels to attach a guy line to. The materials we will be using are pictured...

paracord (material used for the attachment point)

2 clamps

wax paper

Shoe Goo (I LOVE this stuff)

scrap wood

-1 board as a working surface

-2 flat pieces to press everything together evenly

-1 pieces to spread the glue

Step 4: Apply the Glue

Stretch the rainfly, underside up, over the board. Add glue to both the rain fly and the paracord.

Step 5: The Glue Up

Carefully place the glued surface of the paracord to the glue on the underside of the rainfly. Lay wax paper on both sides to prevent any leak out. Then hold a piece of flat scrap wood on both sides to allow for even clamping pressure to the whole assembly. Finally apply the clamps. See order below

Step 6: Attaching Guy Lines

The first photo shows the loop attached to the rainfly after it has dried completely as well as the guy line material.

The next step is to attach the guy lines. I choose to use bungee cord to help absorb and stress put on the tent due to wind. You could certainly use a traditional guy line cord like paracord or bankline. I have two loops of cord pictured. One will be attached to each end of the bungee guy line and hook around the tent stake.

I found the easiest way to attach the bungee guy line to the newly created tent attachment loop is to make an overhand loop in the paracord line then feed the bungee guy line through it as seen in the second photo. Simply flip the loop over the bungee cord and you have essentially created a square not, see photo 3.

Repeat on the opposite end for the loops that attach to the tent stakes Photo 4. Alternatively you can simply tie a loop in the end of the bungee directly or attach a triple slide line tensioner

Step 7: Finished Product

Thats it! You now have a tent that allows for more airflow to eliminate condensation buildup, is more stable and directs rain away from your floor more effectively. This method can be used for all sorts of other mods requiring additional attachment points. I would just encourage you to attach loops on the underside of the rainfly whenever possible.

Happy Camping!!!

    Question 1 year ago on Step 7

    Thank you for your clear instructions. I am very happy to have found them as I want to do almost the same. I was just wondering if this will work when I would do it in the middle of the rainfly as that's where the problem is. (There is already one on the underside of it) And will this glue work for all materials? My fly is made out of 20D nylon coated silicone. My tent is a naturehike cloudup2. It's very thin and I am a bit afraid it will break the fly. Myself I was thinking of adding a extra part of material on the fly and on this material the paracord, but I am really a leak in this. Would love to hear your opinion on this. Best, Saskia

    Nice fix!

    Any thought to sew the paracord loops to the rainfly? I love shoe goo too, but wonder if having it stitched on might be a longer-lasting fix. I'm just thinking out loud here! :)

    Thanks for the kinds words and suggestions, always appreciate alternative approaches.

    I did consider stitching and have done both in the past, shoe goo & sewing, on a project to add sleeping bag attachment loops to the bottom of a backpack. From a strength and durability standpoint it is absolutely the best of both worlds.

    The reason I decided to go with the shoe goo on the underside of the rainfly was to avoid compromising the waterproof liner of the rainfly. If I were to stitch and then coat the top of the stitches with a shoe goo to re-waterproof it, it would look a little unsightly. Just my opinion, would love to hear some feedback from someone who did this project with stitches as opposed to adhesive.

    Thanks again for the feedback!
