Rain has a way of sneaking into even the best-laid camping plans—and nothing ruins a trip faster than packing up early or bedding down next to a soggy tent. That’s exactly why we designed this system to function like a traditional rainfly… and then pushed it quite a bit further.

Constructed from silver reflective, urethane-coated polyester, this rainfly keeps water from ever making direct contact with your pop-top tent*. But its real magic shows up when the weather refuses to cooperate. Acting like a windbreaker for your camper, it blocks biting gusts while creating a protective air gap between the fly and your tent. That buffer zone adds noticeable insulating properties—helping retain warmth in cold conditions and stabilize interior temps when the elements get rowdy.

When the sun comes back out, the reflective silver finish helps keep things cooler inside, so you’re not trading rain protection for a rolling greenhouse. It’s a true all-weather layer, built to handle more than just precipitation.

We also designed it to fully cover the pop-top luggage rack, creating a handy vestibule-style storage area. Zip down the front screen on your pop-top tent and stash bulky gear “outside” without actually exposing it to the elements. Clean, dry, and out of the way.

From cold morning winds to sideways rain, sleet, or even light snow, this isn’t just a rainfly—it’s a year-round shield that keeps your camping setup comfortable, protected, and ready for whatever rolls in next.

Features:

  • All-Weather Performance: Protects against rain, wind, sleet, and light snow for four-season use
  • Wind & Draft Reduction: Acts as a windbreaker to minimize heat loss and improve interior comfort
  • Thermal Air Gap: Adds insulation by creating a buffer zone between the fly and tent
  • Waterproof Material: Durable urethane-coated polyester keeps your tent dry
  • Reflective Temperature Control: Silver exterior helps reduce heat buildup in direct sun
  • Expanded Storage: Fully covers luggage rack to create a functional vestibule area
  • Protected Gear Access: Store items outside your tent while keeping them dry and sheltered
  • Compact & Efficient Design: Low-profile fit without bulky hardware or complicated setup

*While we can't guarantee that this product will keep the pop-top tent, the interior of your camper, or the contents of your camper 100% dry, our testing has shown that it provides a high level of weather protection when it comes time to pop that top!

Step-by-step instructions and hardware are included. Let it rain!

Went camping last weekend at a VW event with a rather sketchy forecast, so I put it on as soon as I popped my top. It stormed and poured off and on throughout the weekend, and my van stayed dry. This thing is incredible.

Found this rain fly in the Vanagon after I bought it, it was not installed and did not come with hardware so I was a bit lost. After a couple hardware store trips and creativity, we are up and dry! The installation took a bit of umph, but overall was an okay experience. Initial set up is hardest, now I can have it up in less than 5 min.
I did use snaps, and am overall pleased with how it looks, how it holds, and how dry the canvas stays. It’s been used about 6 times and dries pretty quick. It could use better gutter strap hooks and maybe heavier duty snaps but overall…. No complaints yet.

Big bang for buck

We use ours rain or shine. It does everything claimed: Kees the canvas dry, reflects sunlight for cooler temps in the heat, insulates. We bought it for the rain, but love it for the extra insulation and extra vestibule. No Westy owner should be without one.

We just spent a week camping in mostly rain. The rain fly kept us warm and dry. Installing the snaps was straightforward. Some of the instructions for the snaps weren’t quite so but we figured them out with little trouble. So worth it.

Generally good product... some components could be better...

The material of the Wasser fly is very good. The male snaps that were screwed in the pop-top did not connect securely with the female snaps... they created a weak attachment. I think I can work with this, but I did expect a more rugged connection in these snaps, needed to hold the fly on in a wind/rain-storm. We'll see what happens. I've been thinking about how I could replace the snaps with a more rugged connection to hold up in a windy storm. The black plastic connector joining the fly's narrow ends at the back of the Vanagon broke in their third connection... I resolved that by adding a short rope to connect the ends of the fly. The snap on the lower end of the pop top (on each side) is located where the gas cylinders are installed to pop the top more easily, and therefore those two snaps could not be installed without removing the gas cylinders, which I did not do... in that location the snaps would have been difficult to connect even if I did remove the gas cylinders to install them. A better placement of the lower side-snap would be helpful. However, I don't think I'll lose much by not being able to snap those lower side snaps.

Needs some improvement

Snaps come off easily. Marine twist lock fasteners should have been used instead. The straps and fasteners up front are good quality but are not long enough to attach to my tube bumper. No way to attach it when running it through the cab.

Hi Keith, we appreciate your feedback and will look at these areas for future improvement. All the best, GW

Weak snaps. Not confident it will do well if there is any wind during a downpour

Material seems good. Appreciate the extra protection at the corners, etc. I can’t seem to adjust mine to a nice “taught” point as the installation pictures show. The snaps are really weak. A light tug and they pop right off. I’m not sure what that is, but it sure feels like the female snap “heads” aren’t catching the male snaps enough. There is no crisp “snap” like the stock curtain holds inside have for example. In fact, the upper snap straps that hold the rain fly along the inside of the pop top on my drivers side pull right off when I attempt to tighten the gutter anchors just to the point where they aren’t falling off the gutters. Once the side snaps pop off, the front corner along the front edge of the pop top pops off too. Which leads me to wonder just how well this will do with any wind.

Installing a Wasser-Stipper

The installation was interesting, I have the HD pop top assist. The attachment for the snap strap is directly in line with the assist. I had to drill the 1/8" hole about 1/2" forward of the assist hardware. I made 2 strips out of leather (5" long with a snap on one end) that made up for the different attachment point

We have won debby !

Debby became a tropical storm in north of Québec (Canada) with winds over 100 km per hour and 150 mm of rain, and we slept in the dry. Thanks GoWesty !

quality is great except for ONE KEY THING

out of the box i was extremely impressed. directions were easy to follow. know that you will have to drill holes into your pop top. the buckles in the front and material are GREAT QUALITY. BUT- the back buckle is garbage in comparison! :( very nice metal buckles in the front… and a crusty plastic buckle in the back that is responsible for holding all the tension of the sides wrapped around? Well, you can guess what happened right after my initial setup. SNAP! the buckle broke in the back. I have no idea why the same high quality metal buckle was not used in THE BACK! we may never know. that being said, GoWesty customer service was top notch and sent me a replacement plastic buckle immediately. when the products fail (which is fortunately rare) at least the company does not! Dear gowesty, we love you. Please change the back buckle, it is junk!

Extra protection

Seems like a good backup to stop rain from getting past the canvas on the pop top. Haven’t had a chance to try it out yet. Mounting was a little difficult but not too bad. Had trouble with some stitching and a snap but Gowesty took care of me.

Great product, instructions could be improved

This is a great idea and a great product. We haven't put it through its paces too much yet, but it's clearly going to keep lots of rain off and appears to be high quality. That said, as has been my experience with several GW products, the installation instructions are a bit of a mixed bag. With this product particularly, there are lots of screws and snaps included, but nothing noting what each is for. The PDF instructions don't mention that for late-model Vanagons, the side straps can just go to existing screws in the tent hold-down rail, rather than drilling new holes. There's also no mention of what size drill bit to use for the side strap mounting holes if you are drilling (presumably the same size as the previous holes drilled in the front, but why not reiterate and clarify?). So 5 stars for the product, -1 star for the missing details in the instructions.

Easy to install

This is GREAT. It is a very easy install with a drill and a friend. Out in the elements, it is a perfect protection from the rain. The little prop stick is excellent and the perfect little tool for quick inclimate weather setup.

Pot-Top Rain Fly

Fits good. Have not tried it in the rain yet ;( Front buckles are over kill. I would prefer high quality plastic (Fastex brand) so they will not damage the paint.

Wasser Stopper Okay?

Don’t get me wrong GoWesty, products are very good, the Wasser Stopper, just has a few issues. One the color is now a super bright silver, not as pictured on the website. I guess this will help reflect the Sun’s rays. Not the best for stealth camping, as you look like a UFO landed. Another thing is where they put the attachment points along the sides of the pop top it interferes with my assistant lifts for the pop top(I use Jack Bombay struts), so I can’t use the rear side snaps. It would have been nice if the 2 front straps were not reversed from each other. Easy to fold up and fit in the provided storage bag. Usual GoWesty quality, should last, but I haven’t tried it in a rain storm yet. Great customer service as always.

Rain Fly easy

Installed but has yet to be tested. It seems durable, well designed. Easy to install.written instructions not provided but downloadable PDF file was simple.
Quality buckles on straps.
My only advice is to add some type of rubber material so straps don't rub on painted surfaces. Im using peices of old inner tube that can be stored in the rainfly bag.
Included are 2 rubber pads for the buckles.

Best alternative to a wet canvas top

It seems to work in foul weather with low winds. Needs to be tethered more for windier conditions. It would be great if the gutter clips were more secure. They find a way to pop off easily since they don’t have much to anchor to. I had a snap on the rainfly break off and bought a snap rivet tool on Amazon to fix. Concept is great, but hardware could use better QC for the price.
