Bear Butt Rain Fly Review: Budget Coverage Champion

I've spent the last three months testing budget hammock gear, trying to find equipment that performs well without breaking the bank. After dropping over $400 on premium tarps that I was afraid to actually use, I wanted something I could put through real weather conditions without anxiety.

The Bear Butt Rain Fly is an 11x9 ft waterproof tarp that costs less than most dinner entrees at outdoor retailers, making it one of the most accessible hammock tarps on the market today.

This budget-friendly tarp from Bear Butt delivers impressive coverage for hammock camping with a waterproof nylon construction that punches above its weight class in the budget shelter category.

I put this rain fly through spring showers, summer thunderstorms, and everything in between to see if budget gear can actually perform when the weather turns rough.

First Impressions

When the package arrived, I was honestly surprised by how compact it was. The entire rain fly stuffs into a sack roughly the size of a grapefruit, which matters when you're counting every ounce in your pack.

Unfolding it for the first time, the 11x9 foot dimensions became clear. This is a diamond-shaped tarp with enough coverage to protect a hammock from driving rain while still maintaining a relatively light packed weight.

The material feels thin but that's actually what you want in a hammock rain fly. Thinner material means lighter weight, and when properly constructed, modern waterproof nylons are incredibly strong despite their gossamer appearance.

I noticed immediately that the tie-out points are reinforced. This is where cheaper tarps often fail, so seeing proper reinforcement at all the critical connection points gave me confidence that Bear Butt understands how hammock tarps actually get used in the field.

Bear Butt Rain Fly - Budget Coverage Champion

What immediately stands out about this rain fly is the sheer coverage area you get for the investment. At 11x9 feet in a diamond configuration, you're looking at enough coverage to keep you dry through sideways rain while still maintaining sight lines around your campsite.

The waterproof nylon construction does its job well. I've spent multiple nights under this tarp during steady rain and woke up completely dry. The water beads up and runs off effectively, which is really all you can ask from a budget rain fly.

Weight is where this tarp really shines. Coming in well under a pound, it's light enough that you won't think twice about throwing it in your pack even on shorter trips where you might chance the weather.

The reinforced tie-out points give me confidence for long-term use. I've pitched this tarp tight in windy conditions and never worried about the corners pulling through, which is something I can't say about every budget tarp I've tested.

Key Features & Specifications

The 11x9 foot diamond shape is the star here. This configuration provides excellent coverage for a single hammock while maximizing the usable space underneath. The diamond pitch naturally sheds water and creates a streamlined profile that handles wind better than rectangular alternatives.

Material-wise, you're getting waterproof nylon that's treated to shed water effectively. It's not the thickest material I've seen, but thickness doesn't always correlate with waterproof performance and durability in modern camping fabrics.

The tie-out configuration deserves mention. With reinforced points at all corners and additional options along the edges, you have multiple pitching configurations available. This versatility means you can adapt the tarp to different conditions and campsite layouts.

Specification	Details
Dimensions	11 x 9 feet (diamond shape)
Material	Waterproof nylon
Weight	Under 1 pound (ultralight category)
Shape	Diamond/rhombus configuration
Tie-out Points	Reinforced corners + edge points
Best Use	Hammock camping, backpacking
Season Rating	3-season (spring, summer, fall)

One feature I appreciate is the simplicity. There are no fancy zippers or complicated attachment systems to fail. This is a straightforward tarp that does exactly what it's supposed to do, which is keep the rain off your head while you sleep.

Real-World Performance Testing

I tested this rain fly across four different states and varying weather conditions over a three-month period. Here's how it performed when the weather actually turned nasty.

Waterproof Performance

The most important test for any rain fly is simple: does it keep you dry? After a particularly wet weekend in the Smokies with nearly two inches of rain overnight, I woke up to a completely dry hammock setup underneath the Bear Butt tarp.

Water beads up on the surface and runs off effectively. The waterproof coating does its job well, and I haven't noticed any saturation or through-water issues even during extended rainfall. The material sheds water nicely rather than absorbing it.

That said, I did notice some minor dripping at the seams during very heavy downpours. This is common with budget tarps that don't come factory seam-sealed. If you're planning extended trips in heavy rain, I'd recommend adding seam sealer to the stitching for extra protection.

Wind Resistance

The diamond shape naturally handles wind well. With a low, aerodynamic profile, this tarp doesn't catch the wind like larger box-style shelters. I've had it pitched in 20+ mph gusts without any drama.

The key is pitching it correctly. A tight pitch with the low edge toward the wind makes a huge difference. I've learned that proper tension is more important than the tarp itself when it comes to wind performance.

Durability Observations

After three months of regular use, the tarp is showing no signs of wear. The reinforced corners are still solid, and I haven't noticed any fraying or material degradation despite setting it up in various terrains from forest sites to rocky alpine environments.

I will say that the material requires some care. This isn't a throw-it-on-the-ground kind of tarp. You need to be mindful of sharp objects and abrasion, but that's true of any lightweight nylon tarp regardless of price point.

Setup & Configuration Options

Setting up the Bear Butt Rain Fly is straightforward, but getting the perfect pitch takes some practice. Here's the basic process I've refined over multiple trips:

1. Attach your ridgeline: Run a cord between two trees at approximately head height when sitting in your hammock.
2. Drape the tarp: Center the rain fly over your ridgeline, positioning it so your hammock will be protected.
3. Stake the corners: Start with the two corners that will form the sides, then move to the head and foot ends.
4. Adjust tension: Fine-tune each guy line until the tarp is drum-tight with no sagging.
5. Test coverage: Sit in your hammock and verify you're protected from expected wind direction.

The diamond shape gives you multiple configuration options depending on conditions. For maximum weather protection, pitch it low with steep sides. For better visibility and ventilation in milder weather, raise one side higher to create a more open shelter.

One setup tip I learned the hard way: attach your guy lines to the trees before staking the tarp. This lets you adjust the positioning before committing to your stake locations, which saves time when you're setting up in fading light.

How It Compares to Alternatives

When you're spending under $30 on a rain fly, the natural question is how it compares to more expensive options. Here's my honest assessment after testing multiple tarps in different price ranges.

vs Premium Options (ENO, Warbonnet, Dutchware)

Premium tarps typically cost 3-5 times more than the Bear Butt. What you get for that extra money is generally better materials, factory seam sealing, and more refined tie-out systems. However, for basic weather protection, the Bear Butt performs 80-90% as well as tarps costing three times as much.

The main differences I've noticed are in material feel and finishing details. Premium tarps feel more substantial, and the seams come sealed from the factory. But if you're willing to do a little DIY work and treat your gear with care, the Bear Butt covers the same essential function.

vs DIY Options

I've known plenty of hammock campers who've made their own tarps from raw silnylon. If you have sewing skills and can source materials at wholesale prices, DIY can save you money. But by the time you buy material, seam sealer, and guy line hardware, you're often in the same price range as the Bear Butt with hours of work invested.

The advantage of buying a complete tarp is that all the engineering work is done for you. The tie-outs are properly placed, the shape is cut correctly, and you can spend your time camping instead of sewing.

vs Other Budget Tarps

This is where the Bear Butt really competes well. Compared to other budget options, the 11x9 foot sizing is generous and the reinforcement at critical points is better than I've seen on similarly priced alternatives. Many budget tarps skimp on corner reinforcement to cut costs, but Bear Butt didn't make that compromise.

Factor	Bear Butt Rain Fly	Typical Premium Tarp	DIY Silnylon Tarp
Price	Under $30	$80-150	$15-25 (materials only)
Factory Seamed	No	Yes	No (you seal it)
Material Quality	Good	Excellent	Varies by source
Tie-out Quality	Reinforced corners	Reinforced + webbing loops	DIY quality
Weight	Under 1 lb	0.75-1 lb	0.5-0.75 lb
Setup Required	None	None	Cutting + sewing + sealing

Who Should Buy the Bear Butt Rain Fly?

This rain fly is ideal for beginner hammock campers who want reliable protection without investing heavily before committing to the hobby. If you're just getting started and aren't sure how much you'll actually use hammock gear, this is a low-risk entry point that performs well enough to satisfy most users.

Backpackers watching their weight will also appreciate how this tarp disappears in a pack. At well under a pound, it's light enough that you'll bring it even on trips where weather looks questionable, which means you'll actually have protection when you need it.

Budget-conscious campers who want maximum value will find a lot to like here. The coverage area and waterproof performance exceed what I'd expect at this price point, making it one of the better values in hammock camping gear.

Who Should Avoid?

If you camp exclusively in severe weather conditions, you might want to step up to a premium option with factory-sealed seams and heavier material. The Bear Butt will handle rain and moderate wind, but extreme weather camping requires specialized gear.

Ultralight purists counting every fraction of an ounce might prefer DIY options or premium ultralight tarps that shave additional weight. While the Bear Butt is light, it's not the absolute lightest option available.

Those who prefer set-it-and-forget-it gear might be frustrated by the need for seam sealing. If you want a tarp that requires zero preparation out of the box, you'll need to spend more for a premium option that comes factory sealed.

Frequently Asked Questions

Final Verdict

After three months of testing across multiple states and weather conditions, I can confidently say the Bear Butt Rain Fly delivers exceptional value for budget-conscious hammock campers. It's not the fanciest tarp on the market, but it covers the essentials reliably.

The waterproof performance is solid, the 11x9 foot coverage is generous, and the weight is low enough that you won't hesitate to bring it on every trip. While premium options offer refinements like factory seam sealing and more sophisticated tie-out systems, those advantages don't justify the 3-5x price difference for most casual users.

If you're getting started with hammock camping or simply want reliable protection without a premium price tag, the Bear Butt Rain Fly is an excellent choice that won't disappoint.
