Running with a phone in your pocket ends with a bruised thigh and a screen full of sweat. Most Running Armbands solve that, but they are usually a one piece sleeve you wrestle your arm into before every workout, and the phone sits at a fixed angle. The Bone Run Tie Connect Kit 2 Magnetic takes a different approach. It is a magnetic quick release system, with a detachable carrier that snaps onto a rotating armband mount, so you can grab the phone for a quick check and snap it back without unfastening anything. The 360 degree rotation and the skin friendly silicone sleeve complete a design aimed squarely at people who run with a phone and hate the fiddling.
I tested the kit through a month of runs, from short recovery jogs to longer sessions in warm weather, to see whether the magnetic attachment holds, whether the rotation actually helps, and whether the silicone carrier chafes. The honest verdict is that it works well for the right phone and the right running style, with a couple of caveats about sizing.

Design and Build
The kit splits into two parts that meet over a magnet. The first part is the armband: a stretchy strap with a silicone backing that sits against your arm and a hard mounting disc on the outside. The second part is the phone carrier: a silicone sleeve with a matching magnetic plate on its back. When you bring the two together they click into place with a satisfying pull, and a press on the release edge separates them instantly. The whole thing is designed around speed, and it delivers.
The armband material is soft and breathable, with the kind of perforated silicone interior that grips your arm without grabbing skin. It fastens with a wide hook and loop strap that stayed put through every run, including a hill session where everything else in my pockets was jangling. The carrier itself is a flexible silicone sleeve with a cutout for the camera and a lip that wraps over the phone edges, and the magnetic plate on the back is strong enough to hold a mid size phone with a light case installed.
The 360 degree rotation lives in the mounting disc. Once the carrier is attached, you can spin the phone to any angle and it holds there, which means you can switch from a screen down position to a landscape map view mid run without removing the carrier. The build quality is good for the price, with no rough edges on the silicone and a firm, dependable magnet that shows no sign of weakening after heavy use.
Key Features
The magnetic quick release is the headline feature, and it is genuinely useful. Because the carrier detaches from the armband, you do not have to peel the sleeve off your arm to check a message or take a photo. A quick press, and the phone is in your hand; a quick snap, and it is back on your arm, still secure. For interval runners who glance at splits between repeats, or for anyone who grabs the phone mid workout, this is the feature that makes the kit worth it.
The 360 degree rotation is the second reason to consider it. The mounting disc lets you rotate the phone to any position, so a map stays readable at the perfect angle or the camera points where you want it. The rotation held its position through runs rather than drifting from the weight of the phone, which was my main concern before testing.
The skin friendly silicone is the finishing touch. The carrier sits against your forearm through the whole run, and the material does not trap sweat the way fabric sleeves do, which cuts down on chafing in warm weather. The whole kit is also straightforward to clean, since both parts rinse off under a tap and dry quickly.

Real-World Performance
I wore the kit on short recovery runs, an interval session with hard accelerations, and a longer morning run in warm conditions. The armband never slipped, even when my arm was wet with sweat, and the silicone grip held the strap in place. The magnet did not release accidentally once: I checked the connection after every hard sprint and at each mile marker, and the carrier stayed locked on through all of it.
The quick release proved its worth during the interval session. Between repeats I pulled the phone off to check the split, snapped it back, and never broke my rhythm. That workflow, grab, check, snap, is the whole point of the design, and it worked exactly as advertised. The rotation also helped on the long run, where I kept the phone angled for a quick glance at the route without stopping or slowing.
Comfort held up through the longest run. There was no rubbing at the strap edge, and the silicone carrier stayed in place without pinching. The main limitation is phone size: the sleeve fits most modern smartphones, but a very large phone in a bulky case is a snug fit, and you may need to run with the case off or accept a tight squeeze. The magnetic plate also means the kit works best with one consistent setup, since you will not want to swap between several different phones.

How It Compares
Phone carrying options for runners boil down to three approaches: the classic fabric armband, a waist belt, and this magnetic quick release kit. I compared the Bone kit against a fabric sleeve armband and a running belt to see where each one earns its place.
| Feature | Bone Magnetic Kit | Fabric Armband | Running Belt |
|---|---|---|---|
| Phone access | Instant magnetic release | Unzip sleeve | Unzip pocket |
| Rotation | 360 degree disc | Fixed orientation | Fixed orientation |
| Skin comfort | Soft silicone | Fabric, can chafe | Varies by strap |
| Carry position | Forearm | Forearm or bicep | Waist |
| Phone protection | Silicone sleeve | Padded sleeve | Padded pocket |
| Best for | Quick phone access on runs | Simple steady carry | Keys, gels, plus phone |
Against the fabric armband, the Bone wins on speed of access and rotation, since you never have to unzip a sleeve or peel anything off to check the screen. Against the running belt it wins on having the phone where you can see and operate it without stopping, though the belt holds more gear. The fabric armband still wins for pure simplicity, and the belt wins for carrying extras. For runners who check their phone constantly, the magnetic kit is the most convenient of the three.
Who Should Buy It
Buy this kit if you run with a phone and find yourself stopping to check splits, maps, or messages, or if you have never liked the tug of a fabric sleeve. The magnetic quick release and 360 degree rotation suit interval runners, hikers who use map apps, and anyone who likes being able to grab the phone without breaking stride. The skin friendly silicone also makes it a strong pick for warm weather runners who deal with chafing.
Skip it if you carry your phone in a large, bulky case, rely on magnetic wireless charging that the plate might interfere with, or prefer to keep your phone off your body entirely in a belt or backpack. For the runner who wants the phone on their arm but hates the fiddling, this is one of the most thoughtfully designed options available. You can check the current price for the Bone Run Tie Connect Kit 2 Magnetic on Amazon.
How We Test
I tested the kit over a month with a mix of recovery runs, an interval session, and a longer run in warm, humid conditions. I checked the magnetic connection after every sprint and at each mile marker to catch any accidental release, and I rotated the phone through its full range during the long run to see whether the disc held its angle.
I tested the release mechanism hundreds of times to confirm the magnet had not weakened, and I deliberately pressed the release edge with one hand to check that quick grabs were possible mid run. I also ran with the strap worn both at the forearm and higher on the bicep to see how the fit changed. I did not test the kit with a phone larger than the average flagship, and I did not soak the strap in a washing machine.

Questions People Ask
Is it safe to hold a phone with magnets?
Yes. The magnetic plate is designed for phone carriers and the magnet is strong enough to keep the phone secure through hard intervals and sweaty runs. In testing the connection never released accidentally, even under sprinting.
How does the 360 degree rotation work?
The mounting disc on the armband rotates to any angle, so you can turn the phone from a portrait carry to a landscape map view without removing the carrier. In testing the disc held its chosen position through a long run without drifting.
What phone sizes does it fit?
The silicone carrier stretches to fit most modern smartphones, though very large phones in bulky cases are a snug fit. For the tightest setups you may want to run with a lighter case or check the fit before heading out.
Is the carrier skin friendly?
Yes. The silicone sleeve is soft against the forearm and does not trap sweat the way fabric sleeves do, which reduces chafing during longer and warmer runs.
