- Panel pull kit is no longer available for purchase. Only in-stock models are available for purchase currently. We add more hammock inventory in weekly. If you make a complete selection of an out-of-stock item, checking all boxes including color, suspension etc, you should see a blue box down below the add-to-cart button that allows you to enter an email address for an email notification when that color/model is added back to inventory. If every color within a variation are out of stock, then the box may not appear unfortunately and you’d have to just check back, but using the email notice is the best option if you are able. We recommend signing up for a couple different color choices to ensure faster notification.
We’re happy to introduce the ThunderFly as one of our newest tarp designs. This rain fly tarp is built for those that want the simplicity and convenience of a standard hex tarp but with extra end-coverage when the weather gets nasty.
We’ve taken the standard hex tarp and given it major end-coverage that can be deployed as needed by adding a split-beak (small doors) to the ends that can be clipped together and deployed with a single guyline to add a significant amount of end protection right where you need it (higher up near the ends of the hammock where a standard hex shape offers the least coverage). When the weather is nice these small doors simply stay clipped back and out of the way until you need to deploy them. Once deployed, the rain fly tarp will protect the hammock from windblown rain coming in from the ends of the tarp.
Looking for something slightly lighter/smaller? Check out our MiniFly tarp model, it’s a slightly downsized version of the ThunderFly and will save you a couple oz while still offering great coverage
We offer all our rain fly tarp models in 11′, 12′ and 13′ lengths. This length refers to the length of the Ridge-seam. In general, the 11′ tarps are most appropriate for end gathered style hammocks like our Blackbird, XLC and Eldorado, while the 13′ versions are best suited for bridge hammocks like our Ridgerunner. The doors on any of our 13′ “Fly” series of tarps will fully close around the suspension triangle of the Ridgerunner.
We also offer a 12′ option which would be most useful on a Hex shaped tarp like our Mamajamba, with the 12′ MJ giving more end coverage than the 11′ MJ.
Unlike the MJ hex tarp, this tarp with doors does NOT see an increase in end coverage by jumping from 11’ to 12’ version.
We are currently offering rain fly tarps in both Polyester and Nylon options (camo print available in Polyester ONLY). The Polyester fabric is more stretch resistant and has lower water absorption, while the Nylon is a stronger more durable fabric. Both are good options, weights are similar for each. Both fabrics have a minimum 2000mm hydrostatic head waterproof rating.
The Thunderfly now comes stock “without” panel pulls. You can still order them with panel pulls, to do so

So on an 11′ end-gathered style hammock, an 11′ rain fly tarp will give more coverage down low than 13′ would. But on our Ridgerunner bridge hammock, there is no ridgeline and the hammock is usually hung a little flatter…so you can get a 13′ tarp to come down for sufficient side coverage. The 13′ also allows the doors to fully shut on the Ridgerunner, the shorter 11′ tarp with doors is also appropriate for a Ridgerunner but the apex of the RR’s suspension triangle will poke out between the doors, creating a small opening. Bumping to a 13′ eliminates that issue, but is not necessary… the opening is a narrow vertical slot that is about 3 feet beyond the ends of the hammock fabric. There is a photo of the RR suspension triangle poking through the door slot in the gallery on the Thunderfly page for reference.
The MiniFly and ThunderFly are both good lightweight 3-season rain fly tarp options. You also can add our Underquilt Protector to the bottom of your XLC/Eldorado and turn either of these tarps into a solid winter shelter. On their own, both provide good 3 season coverage. For someone looking to go minimal I would recommend the Thunderfly for a true 3 season tarp in the Rockies or Sierra/Cascades where you might actually encounter snow, freezing temps, and high wind in spring and fall, while the Minifly would be more than adequate as a 3-season rain fly tarp in anyplace you don’t expect lots of cold wind. The ThunderFly is simply 12″ wider so offers more wind block (which is more important the colder it is)
The Superfly is our best-selling tarp with doors because it is our “all season/all weather” tarp model. The main reason someone might select a different model tarp would be if they want to save pack weight in the warmer months when the Superfly coverage is overkill for the conditions and weight savings is more desirable. Other than a little extra weight, there is no real downside to using the Superfly in warmer conditions. For information on choosing the right tarp for you, see our Tarps 101 page.
The 30D Silnylon is slightly more durable than 20D Silpoly.
In general nylon has a higher tear and tensile(breaking) strength than the same weight polyester simply because nylon is all-around stronger pound for pound than polyester is. Poly will stretch less (when soaked or otherwise) and it will absorb less water weight. Poly still stretches some, just not as much as nylon. The extra stretch of nylon adds to its strength though, in that it acts as a built in shock absorber during a heavy wind gust, so with poly stretching less in that situation, in theory the nylon rain fly tarp would have a lower wind load due to extra stretch.
We’ve had excellent long term durability results from our 30d Silnylon.
Ploy is said to have better UV resistance, but don’t think you can treat your rain fly tarp any differently than before, we tested a polyester tarp with doors outside for about 2 months and the fabric lost ALOT of strength from the sun exposure, so you still want to avoid things like that regardless of whether your tarp is poly or nylon.
Our 11-foot hammocks have a ridgeline length of 112″ (the body fabric hangs in an arc) so with an 11′ (132″) tarp this gives you 10″ of rain fly tarp overlap at each end of the hammock. If the tarp has doors then those doors will be able to shut or overlap enclosing you all the way around. How far down does the tarp come? This depends on tarp width but also how high you hang it up above the hammock, hang it higher and it doesn’t come down as far . Your hammock suspension runs uphill at an angle and the tarp is longer than the hammock, so you can only pitch the tarp so low that it contacts the hammock suspension. So the longer the tarp length the higher you have to pitch it above the ridgeline of the hammock and the more coverage you lose down low. Generally go for the 11′ Fly series tarp with any of our 10′ or 11′ end gathered models like the Blackbird, XLC and Eldorado. This will give max wind block down low near the bottom of the hammock.
All of our rain fly tarp models come with a single-ended stuff sack included. Recommended items are listed on each tarp page.
