SPIbelt Running Water Bottle, H2O Hydration Companion, 8oz BPA-Free Sports Water Bottle – No Bounce, Leak-Proof Design, Clips to Running Belts or Shorts, Lightweight Fitness Water Bottle

I like this water bottle, it has just enough water to refuel midway through a hike without adding the weight of a normal and heavier water bottle. I did notice, as some others mentioned, that the bottle cap sometimes seems to leak. I found out through about 12 hikes that this occurs sometimes when the cap is not "evenly" screwed onto the grooves of the bottle itself. By way of explanation I have sent three pictures to illustrate the cap screw issue and a potential consideration for a clamp design change in later versions. The 1st picture shows the white bottle by itself and the neck threads of the bottle. You can see where there are 3 distinct grooves for the cap to engage. The 2nd picture shows the white bottle with the installed collar/clamp assembly fitted over the bottle neck opening. Not that the collar covers up the last of the three threads at the base of the neck of the bottle. It also could be that this loss of the last thread contributes to some of those times when leakage occurs. My sense is that the bigger issue is that folks are in a hurry to fill the bottle and they just start screwing the cap on even though it is not lined up properly, and if they stop screwing when they meet the resistance of the collar thinking the cap is secured then perhaps some water will come out when the bottle is turned upside down. One last observation for future clamp design considerations. The 3rd picture shows the collar/clap and cap installed with a normal 1 and 5/16ths inch leather belt which I use to hold both the water bottle and other assorted gear on hikes You can see clearly the pressure "fairings" on the clamp between the inside of the clamp and the belt. Note that the belt is wider than the SPIBelt (which I think is 1 inch in width). My belt is a pretty standard belt width and if the fairings were designed to be located about another 5/16th of an inch lower on the clamp it would much more securely hold the water bottle,...and make the bottle much more compatible with the overall water bottle user community, I think. I have experienced the bottle becoming partially or fully dislodged from the belt when I am entering or exiting a vehicle. Not a big deal to a user but something to watch for when using.

In my mid-twenties I've tested every conceivable way to stay hydrated on long runs—bulky handheld straps that bounce incessantly cheap collapsible flasks that leak at the worst moments and overbuilt belts with bottles that slosh like maracas. Most feel like compromises designed by people who've never logged serious mileage. After digging into options I chose the SPIbelt H2O Companion 8oz and it's the first hydration solution that feels purposefully engineered rather than an afterthought. The design is deceptively simple yet brilliant. The adjustable hand strap secures the lightweight BPA-free bottle firmly without cutting circulation and the ergonomic shape nestles perfectly in the palm for a natural grip. At 8 ounces it's just enough capacity for half-marathon distances without unnecessary weight and the leak-proof cap with pull spout works flawlessly even mid-stride. No fumbling no spills just reliable access. A month ago I was tackling a humid 15-miler on technical trails where my previous handheld had turned every step into a distraction—the strap chafed the bottle shifted and I ended up dehydrated and irritated cutting the run short. Switched to the SPIbelt for the same route and it disappeared into the background. Grip stayed secure hydration came effortlessly and I finished strong with a negative split actually enjoying the effort instead of managing gear. That seamless experience let me push harder and recover better. What separates this from competitors is the thoughtful integration—it's contoured to minimize bounce far better than generic amphipod-style holders and lighter than Nathan or FlipBelt equivalents without sacrificing durability. The strap adjusts precisely for bare hands or gloves and the bottle detaches easily for cleaning or refills unlike clunky integrated systems that trap residue. I've put hundreds of miles on it through washes and varying conditions with zero wear on the strap or degradation in the bottle. For runners who demand gear that enhances performance rather than hinders it this is the standout choice. It's not flashy but it's refined and effective. Easily the best running hydration I've owned.

I've used this on Long runs (15-20mi) clipped to my SpiBelt. It's nice and small which I like, but sometimes it falls off, so trying to figure out how to stop that from happening.

Perfect for my 1-hour hike, just the right size. - not too big, so it doesn't weigh down my belt/pants. The belt clip is secure and easy to get on/off. - seems just about perfect amount of hydration. I usually get home with a little water left. first time I used it it leaked, but seems I had not aligned the clip and the lid didn't screw down all the way. Now I am a little more careful to align and screw down the lid and all is well.

When walking, this belt water bottle works fine with all my random belts. It does tend to leak a bit when it's full unless the top is rotated very tight and the nipple is depressed. It provides a very convenient service of a light-weight water supply to satiate a dry throat when out on a short hike.

Leaked from the beginning, unable to drink out of it without it spilling from the sides. Didn’t matter how much I filled it. Was going to return, but couldn’t make it back before the deadline due to traveling. So ultimately paid for a piece of useless plastic.

Works great. I wasn’t sure about ordering when I read reviews saying that it leaked, but I haven’t had any issues at all. Filled easily and stayed put on my SPI belt for multiple 6+ mile runs.

works well just not good enough for long days

My favorite water bottle for running.

Muy buen articulo, exacto el que esta en las fotos y el que queria...

It bounces, below my expectation. It’s to big to hold, yet too bouncy to hang on your hips/waist.

Super disappointed, definitely can't run with this bottle on the belt system moves way too much and was so distracting. Had to order a running vest instead.
