Marathon Trail Running Waist Pack – Dual Pocket Sports Fanny Pack for Phone & Water Bottle

Your phone stops slapping your leg at mile three

Every runner solves this badly at least once. The phone goes in the shorts pocket and beats against your thigh with every stride. It goes in your hand and your arm never relaxes. It goes in an armband that slowly rotates until the screen is facing your ribs. And water is a separate problem entirely, so you carry a bottle in your fist for an hour or plan the whole route around a drinking fountain.

This waist belt takes care of both at once. A zipped pocket across the front holds your phone and keys, and an angled holster on each hip holds a water bottle that is already in the box. You run hands-free, hydrated and ready from the first step, with no hunting for flasks that fit.

Room for your big-screen phone

The front pocket is rated for phones up to about 6.6 in. That is the screen measurement you see on a spec sheet, and it covers the large-screen phones most people carry, the Plus, Pro Max and Ultra sizes included.

The pocket is stretch fabric rather than a rigid sleeve, so it gives around a phone in its everyday case and holds it snug while you run. It runs horizontally across your front, roughly the length of your hand, so the phone lies flat against you instead of standing on end.

One size fits waists from 27.5 to 59 in

The strap measures 27.5 in (70 cm) at its shortest and stretches to 59 in (150 cm), so it covers small waists and large ones, worn over bare skin or over a winter layer. Set the length once with the slider, then it is a side-release buckle: one click on, one click off, with no re-adjusting every run.

The belt is a narrow band, no taller than the width of your hand, so it sits in the hollow above your hip bones rather than across your stomach. Wear it at the front for quick access, or spin it round to the small of your back, the way runners do with a race bib pinned on the front.

Two bottles, one on each hip

Both water bottles come with the belt. Each one sits in its own fabric holster, angled outward and nose-down, so you can pull one free with the hand on that side without breaking stride and push it back the same way. Push-pull sport caps let you drink one-handed with no lid to unscrew.

Carrying one on each side is why this design beats a single-bottle belt: the weight is balanced across your hips instead of dragging on one side, so the belt sits steady as you run.

A short elastic drawcord beside each holster cinches down over the bottle on rougher ground. Swap a bottle out for a gel, a folded buff or a compact windbreaker whenever you want the space.

Set it once and it stays put

Snug and low is the whole trick, and it takes about five seconds. Pull the belt a little tighter than feels natural at a standstill, so a flat hand will not slide between it and your body. The elastic gives as you move and the belt stays exactly where you put it.

Then drop it onto the shelf of your hip bones rather than the soft part of your waist. Bone holds it in place. Put a bottle on each side and the phone in the center pocket, and the load is balanced for the whole run.

Built for the run, in all weather

Reinforced stitching and water-resistant material give the belt long-lasting durability for all-weather running. The fabric is a stretch knit that moves with you rather than a stiff nylon shell, which is what lets the pocket hug your phone.

Narrow silver-grey reflective strips sit beside each holster, adding visibility on early-morning, evening and low-light runs. A small port at the front of the pocket lets you run a wired headphone cable up to your ears with the phone zipped safely away.

Run with it, risk free

Every belt is backed by our 90-day money-back guarantee, so you can take it out on the trail and make up your mind with miles behind you.

Frequently asked questions

Do the water bottles come with it?

Yes. Two bottles are included with every color, so you are choosing a trim color and the bottles come along either way. You do not need to buy flasks separately or work out which ones fit the holsters.

Is one size going to fit me?

Yes. The strap runs from 27.5 in (70 cm) up to 59 in (150 cm), a much wider span than most belts offer. Measure where you want to wear it, low across the top of your hip bones, rather than at your natural waist.

Will my phone in a case fit?

The pocket is rated for phones up to about 6.6 in, and the stretch fabric gives around a phone in its everyday case. For a bulkier case, measure the case rather than the handset.

How do I keep it from bouncing?

Cinch it a little tighter than feels natural standing still, wear it low on your hip bones, and put a bottle on each side so the weight is balanced. Set up that way, it stays where you put it.

Are the four colors different belts?

Same belt, different trim. The belt body is black in all four, and the zip and the two drawcords come in black, blue, orange or fluorescent green. Pick the one you like.

Can I use it for hiking, cycling or walking the dog?

Yes. It is the same belt for a hike, a bike ride, a dog walk or a day at a theme park, and the two bottles matter more the longer you are out.

How do I clean it?

Empty the pockets, hand wash in cool water with a little mild detergent, and air dry away from direct heat to keep the elastic springy. The bottles come out and wash separately.
