Female urination devices for hiking, compared

By GO! Editorial Team ·October 4, 2026

A female urination device (FUD) lets you pee standing up without dropping your pants. On a windy ridge, in a busy trailhead lot, in a climbing harness or in a sleeping bag at 2 a.m., that is not a gimmick. It is the difference between a 30-second stop and a cold, exposed squat.

This guide compares the devices that are easy to buy in the US today. We compared manufacturer specifications and the design of each device: material, weight, length, number of parts and what comes in the box. We have not run a lab test, and we say so wherever it matters.

Quick picks

How we compared them

We judged each device on six criteria, using the manufacturer’s own specifications. Where a maker does not publish a figure, the table says so instead of guessing.

• Weight: matters most on long hikes, where every ounce is carried all day.
• Length: a longer spout carries the stream further from your boots and pant legs.
• Material: decides whether the device holds its shape through clothing or packs small (see the next section).
• Parts to clean: tubes and hinges trap moisture; one-piece devices dry fastest.
• In the box: a case or tube keeps the device away from the rest of your gear.
• Made in: for readers who prefer to buy locally made gear.

Rigid, flexible or disposable?

The material decides most of how a device behaves on the trail.

• Rigid (pStyle, Shewee Extreme): holds its shape when you push it through a fly or under a waistband, so it does not fold and spill. The trade-off is bulk in a pocket.
• Flexible (Shewee Flexi, silicone funnels such as GoGirl): rolls or squashes into a small pocket. Soft silicone can collapse if you grip it too hard, a common problem with soft funnels.
• Hybrid (Tinkle Belle): a hard cup with a folding spout. It packs short and stays rigid where it touches your body.
• Disposable (cardboard funnels such as Pee Pocket): good for a festival or a one-off trip. On a long hike you have to carry every used one out, so they make little sense for regular use.

The devices

pStyle: best overall

The pStyle is a single piece of rigid polypropylene, 7.5 inches long and 0.8 oz. The back of the funnel is open, so there is no closed tube where urine can back up. The rounded rear edge works as a squeegee, which means you need less toilet paper.

• Good: lightest rigid device here; made in the USA; the mirror-smooth surface sheds liquid, so a shake or a splash of water cleans it.
• Watch out: the open design needs correct placement and a slight forward tilt. Expect a few practice runs before you trust it.
• Best for: day hikes, thru-hikes and anyone counting ounces.

The current version is made with recycled ocean plastic in partnership with Oceanworks.

Tinkle Belle: best for beginners

The Tinkle Belle combines a hard cup with a long folding spout: 9.25 inches unfolded, 2 oz. The length is the point. It carries the stream well away from your boots and pant legs, which is where most beginners get wet.

• Good: the hard shell does not collapse through clothing; a soft squeegee lip removes the last drops; it comes with a case.
• Watch out: more parts to clean than a one-piece device, and twice the weight of the pStyle.
• Best for: first-time users and anyone who wants maximum distance from the stream.

Shewee Flexi: best packable

The Shewee Flexi is made in the UK from flexible polyolefin and weighs about 32–35 g. It is larger than the Shewee Extreme, and the material flexes without going floppy. It ships with an extension pipe that improves aim.

• Good: packs into a hip-belt pocket; the extension pipe helps when you are wearing bibs or a harness.
• Watch out: with the pipe attached, rinse it well; a tube is harder to dry than an open funnel.
• Best for: travel, festivals and hikers who want flexibility without silicone’s collapse risk.

Shewee Extreme: most durable

The Shewee Extreme has been made in the UK since 1999 and was the first device of its kind on the market. It is hard polypropylene, 3.5 oz, with an extension tube and a carry case.

• Good: nearly indestructible; a proven design, on the market since 1999.
• Watch out: the heaviest option here, and its smaller funnel is less forgiving than newer designs.
• Best for: winter, mountaineering and anyone who will throw it in a pack and forget about it.

GoGirl: best US-made silicone

GoGirl is a one-piece funnel of medical-grade silicone, made in the USA. The angled spout directs the stream forward and away from your feet, and the device rolls up into the storage tube it ships with. The maker says the silicone is antimicrobial and water-resistant, so on the trail a shake and a wipe is enough; wash it with soap and water at home.

• Good: one piece, nothing to assemble; soft against the body; the storage tube keeps it separate from the rest of your gear.
• Watch out: like any soft funnel, it can fold if you squeeze it while pushing it through clothing. Published weight and length vary between retailers, so we have not included them.
• Best for: hikers who prefer silicone to hard plastic and want a device made in the USA.

Sunany silicone funnel: best soft silicone

The Sunany funnel is soft silicone with a large cup and a long spout, 6.7 inches (17 cm) tall. It folds into its drawstring bag. Its size makes it forgiving while you learn placement.

• Good: comfortable against the body; rolls up small; easy to wash with soapy water.
• Watch out: the large funnel is awkward to fit inside a waistband; squeezing it too hard can make it fold.
• Best for: car camping, travel and practice at home before switching to a rigid device.

Note: the listing does not give a reliable weight, so we have not included one.

Pee cloth: the accessory that completes the kit

A FUD solves the standing part. A reusable pee cloth solves the drip-dry part without toilet paper, which you would otherwise have to pack out. This silver-infused polyester cloth is a simple option that you clip to the outside of your pack to dry.

If you prefer to buy from a small brand, Kula Cloth makes a similar cloth with an antimicrobial absorbent side, a waterproof printed side and snaps to clip it to your pack. It is hand-sewn in the USA and sold directly by the maker.

How to use a FUD without getting wet

1. Practice in the shower first. Every body is different, and placement takes a few tries. Do the learning where a spill does not matter.
2. Place the cup firmly against your body, covering the urethra, with the back edge well back.
3. Tilt the spout down and forward. Gravity does the work; a level spout is how overflows start.
4. Start slowly. Relax and let the flow build. A full-force start can overflow any funnel.
5. Stand with your back to the wind.
6. Finish with the squeegee edge or a pee cloth, then shake the device and store it.

Cleaning and storage

• On the trail: shake it, rinse it with a splash of water if you can spare it, and store it in a dedicated pouch or zip bag on the outside of your pack.
• At home: wash with warm soapy water. Smooth rigid plastic is the easiest to clean; tubes and folds need more attention.
• Hygiene: keep the device in its own bag, away from food and water bottles.

Leave No Trace

Pee at least 200 feet (about 70 adult steps) from lakes, streams, trails and camp. Choose rock, gravel or pine needles over vegetation, because animals dig up plants to get at the salt. Never leave toilet paper behind: pack it out, or use a pee cloth.

FAQ

Can I use a FUD without unbuttoning my pants? Yes, with a fly. Rigid and hybrid devices (pStyle, Tinkle Belle) go through a zipper fly most easily. With leggings, pull the waistband down in front only.

Which one works best with a climbing harness? A rigid device with a longer reach, such as the Shewee Extreme with its extension tube or the Tinkle Belle, lets you go without unclipping your leg loops.

Can I use one in a tent at night? Yes, if you pair it with a dedicated wide-mouth bottle that you never use for drinking. Label the bottle clearly and practice at home first.

Rigid or silicone for a first device? Rigid. Silicone feels friendlier, but it collapses more easily when you push it through clothing, and that is a common source of first-time spills.

Our verdict

Start with the pStyle if you hike often and care about weight. Choose the Tinkle Belle if you have never used a FUD and want the most forgiving option. Add a pee cloth either way, and practice in the shower before your first trip.
