    1. Works great

      My iPhone 7 fits (snuggly) into the zippered section and the outer section held my water bottle.
      The belt is comfortable and secure.
      I would add that the online assistance with my order was great!
      Good job UD!

    2. Light weight, secure, plenty of room

      I use a Pixel phone for music when I run and this fits great, there is plenty of room for lots of running/biking essentials. The only reason that I didn't give it five stars is that it the material doesn't breathe well so your belly or back where ever you wear it gets a little sweaty. on Jun 3rd 2017

    3. this thing is great but...

      this bel is great, i wear it all the time, the only thing that would make this belt better is if i could buy the stereo flip up pocket by its self to add to the mono with out having to buy the entire stereo. for those long 50 or even 100 mile race i prefer a couple of the other guys 12oz exo shot flasks in the hands and one flask in the belt, so storage on the mono for other needed items would be perfect. absolutly perfect on May 18th 2017

    4. I love the entire Groove System!

      I bought the entire Ultimate Direction Groove System (AMP, Mono belt, and Stereo belt) in May for my fall marathon's summer training. It gets hot and very humid in Southwestern Pennsylvania, so I opted to go with the Groove system because I thought they'd be cooler than the vests. I bought the entire system for a few reasons--I have a big cell phone, I'm not a fast runner and like the idea of having extra water with me, and a few others. Here's what I've learned about these products after three months of long, medium, and short runs.

      The AMP:
      Yes, it takes a few runs to get used to to what another reviewer called the "soggy baguette" feeling of a half full bottle. The body bottles are soft and have no structure when they are empty. However, after 3 or 4 runs I really didn't notice a problem. I adjusted to the feel and it's no longer a problem. I like the ability to strap the AMP to my hand with the "X" shaped straps on the back; however, as the bottle is consumed, I find that I don't use the straps and move the bottle from my right to left hand as I go. Whatever is comfortable. Again, I love a handheld and feel strange running outside without one--even take one with me on 5K's! The two pockets on the outside are about the size of a gel pack each and there's a small velcro pocket on the bottom big enough for a few electrolyte capsules. I don't use gels, and since the side pockets don't have closures, I really don't use them for anything. I have put my car key in the side pocket and clipped it to one of the bottle straps for fear of loosing it.

      So, for the AMP--I love it.

      The MONO Belt:
      I bought this belt because I have a Samsung Galaxy Note 5. It's a big phone, but when you add the case, it's even bigger. The description of the Mono says it's iPhone 6 Plus compatible (which is about the same size as my Samsung) so I bought the belt more for carrying my phone than carrying water. It fits great, doesn't bounce and has a small velcro pouch on the right side that holds my car key perfect--I think it's meant for electrolyte capsules. The zippered pocket is moisture proof will hold my phone outside of the phone case. It won't fit with the case on. However, the outside pouch that's meant for the water bottle holds my phone perfect. If there's a slight chance of rain, I put my phone in a zip lock bag ad don't worry about it. The front part of the belt can be swapped out for the front part of the Stereo belt that has pockets and creates a new system. I use the combined system occasionally because my phone does fit in the front pocket of the Stereo and I can carry an extra bottle of water in the Mono portion.

      So, the Mono--I love it.

      The STEREO:
      I bought the Stereo with the bottles. My older, rigid UD bottles will fit in the Stereo without a problem, but I liked the idea of the Body Bottles fitting up against me and reducing bounce. The Body Bottles aren't cheap by themselves, and there's a definite cost savings buying the belt with the bottles. The belt fits well and doesn't bounce. My phone fits in the front zipper pocket, albeit a snug fit, but it fits without fear of damaging the belt. The front pouch also has two pouches that would be great for gels or such. I use one for my electrolyte capsules and the other is usually empty. The back portion of the belt holds two body bottles and has a zippered pouch that will hould a fair amount for a belt. I put a 300 ml soft flask with my nutrition in this pouch on my long runs and it fits without a problem. When my hand held is empty, I blow it up with air and swap it out for a full bottle from the Stereo--blowing it up makes it easier to get in and out of the belt. On my really long runs, three bottles aren't enough, so I have to plan having a place to fill up my empties--a water fountain, convenience store, or even circling back to my truck.

      So, the Stereo belt--You guessed it.... I love it.

      I really can't find anything about the Groove system that I don't like. The bottles do warm up pretty fast (I'm guessing it's because of the thin nature of the bottle and lack of insulation,) but since I only put water in them it hasn't been an issue.

      Hope this review helps you in your decision!!!

    5. Impressed!!

      I bought primarily as an alternative to carrying my poles at times during UTMB and also for an an additional water store. I've been training with it and love it!! I'm super excited to bring it to Chamonix!! on Jul 13th 2016

    6. The best fit yet of any waist belt I've tried!!!!

      Easily carries my id, cards, keys and iPhone plus 6 with some room to spare. You can hardly feel it's there at all with no bounce and no chafing!! Love it!!

    7. very good kit!

      I love the Groove Mono. I bought it for shorter trail/road runs where it wasn't necessary for me to carry lots of water or kit. I recently ran a trail up to 2200 meters in the Tatra mountains in Poland wearing just the Mono and one body bottle and it was just right with very little movement. The inner zipped pocket is great for gels etc. My only dislike I have is the closing system for the main pocket. The loop and hook system is annoying to open and close when on the move. It just takes too much effort to open when running. on Jun 28th 2016

    8. Hands down - Best belt system available

      Actually bought the mono with a separate stereo pack (holds 2 bottles) to interchange for longer runs. Very lightweight and comfortable. I choose it over hand-held bottle even for shorter runs because it allows for a normal gait. on May 31st 2016

    9. The Groove Mono rocks..,

      Tried the Mono out after trying multiple other waist belts that hold a water bottle. The Mono is the best I've tried. Fits great. Easy adjustments even while you're running. Most impressive is NO BOUNCE. I carried the Body Bottle and my iPhone. Don't even feel it when running. I'll be giving the other waist belt to a friend but I'll be honest and say the mono is much better. Great design-stable with a load, very comfortable and good design feature. Also picked up the Stereo for longer runs when I don't want to wear the SJ vest. You won't be disappointed. on May 25th 2016

    10. Great product once you adjust it correctly

      I have been able to test it on different conditions and I think it is safe to say that this is a great product. I used it with and without the bottle, and it does not bounce as much as you would expect, as long as you fit it correctly by firmly tightening the belt.

      I ran 8 miles at the mountains yesterday with an elevation gain of 1300 ft and the belt was always in place. I am very satisfied, but it took me a couple of times to get the right adjustment, and once that was set, I was very happy.

      The inner pocket is not big enough for an Nexus 6P (or an iPhone 6 Plus), but you can carry the phone safely with the soft bottle.

      The only reason I am not giving it a 5 star review is because the logos are gone after a few runs, although that is not important for me since it performs as I want it to.

    11. Didn't even know it was there

      I was skeptical because it was significantly bigger than the Jurek belt. I ran 19 miles in it and was very pleased. I did not use a bottle in it but i did have a shell and calories and keys and headlamp. Nice to have the stash pouch and a zipper pocket as well. Really great belt. on Feb 16th 2016
