Ultimate Direction Jurek Endure Waist Pack

This is definitely a lightweight waist pack, and has some decent storage for being as light as it is, but it fails at the primary purpose for which it was bought. As soon as you start running and the liquid starts sloshing, it starts leaking from the bottles. I can't for the life of me understand why no one who makes these types of bottles can be bothered to put a rubber gasket in the lid to prevent this. You can fill the bottles halfway, but what's the point in that? It's advertised as having two-10 ounce bottles, not two bottles than can hold up to 5 ounces without leaking. You can also put plumber's tape around the rim, but why should someone who purchased this item be forced to modify it just to get it to do what it was sold to do?Another annoying part of this belt is the way it will constantly move around your wait- you set it up and get it nice and tight. Then you start running, and before you know it, the bottles are moving toward the front. It appears that the belt loosens over time, so a clip to lock it in place would probably fix this.This is not a very expensive waist pack, but between the baffling leak problem and the sliding problem, I'm still disappointed in companies like UD who continue to overlook such simple yet glaring design flaws.

I wanted to love this, but sadly, Im returning it.First the pros:I run with my phone and prefer to have it in front, So the pouch was important to me. Its big enough for my phone (Iphone5, with small case that holds credit cards and headphones plugged in) as well as room for the emergency Ziploc bag i carry as backup rain protection. It rides on the front and can slide along the strap for a perfect fit, while the bottles ride along the back. perfect for me.I love the pocket between the bottles for storage of gu (or whatever)!Love the concept of the bungee cord to hold a jacket i need to take off or whatever. (Never got to use them though)Hate that theyre orange! Kinda just want the whole thing to be black or black and gray, but whatever.Bottle capacity was great. Bottles felt secure in the belt. I did drop one while trying to take it out while running, but practive would probably improve that.On to the bad...It bounces a lot! And worse yet, it spins! Literally, around my body! From the back around the side, to the front, around the other side tangling my phone cords and making me insane! I tightened to the point of discomfort. Adjusted. Stopped. Started. Cursed. Tugged, Pulled. For a while I was just running holding onto it! On the first trial run, I went 5 miles. Meant to go more, and even though it finally settled kind of side saddle on my right hip, (one bottle in front and one it back. it was weird) I still couldn't complete the 7 mile run I intended. I gave it a second chance in different clothes, figuring maybe they effected it, but no luck. I ran to the edge of the neighborhood and gave up in frustration. One reveiwer mentioned his pace mightve been a factor. My pace was just under 9min miles. About the same as his, so maybe thats a contributing factor? Regardless, I have no intention of getting any slower, so its going back! I also got the fitletic belt at the same time, and though its not perfect either, Im keeping that one. Ill be reviewing it too, if youre interested. Hope this helps!

I bought this waist pack in the hopes that it would serve as my lone encumbrance for hydration and nutrition for my long runs and long-ish tempo runs. Unfortunately, I found it apt at neither.PROs: * Quality build * Balanced when bottles are about the same level * Spacious for its size * "Feather" weight.CONs: * If you go faster than 9min/mile or so, this belt will start shifting up and down and to the sides, even if buckled uncomfortably tight. * The strap loosens after a few miles, which means you'll need to stop to re-tighten it. * When drinking out of a bottle, specially if both are fairly full, the waist pack loses a fair amount of balance and there's considerable shifting.Overall, it's a great belt pack that I would personally use for hiking trails, but definitely not as useful as a Marathon training hydration/nutrition companion.

This is the best waist pack I have ever owned - and I have owned a bunch of them. Dual bottles makes the difference - it's all about balance. When I ran with packs that had only one 20 oz bottle, the pack would move around on my waist, no matter how snug I made it. This one stays in place through my entire run. The zippered pouch is easy to get to - so if you get a phone call while you're out running, you can easily grab your phone.The pack is made of light, breathable synthetic fabric, which keeps it light even when wet, and dries in minutes, not hours. There is no bad smell on the pack after running with it day after day without a wash.The only con I can think of is that the water bottles, being in the back, are a bit hard to reach on the run. That's why I'm buying the Ultimate Direction Jurek Bottle Grip - which comes with a BPA free 20 oz bottle. So I will use the bottle grip for my main source while running, and the two 10 oz bottles on the waist pack as reserve, or for my nutrition drink.Honestly, the main reason I bought this pack was that I happen to like Scott Jurek a great deal - I even ran with him in NYC a couple years ago. He is a great guy, and deserves every penny he makes from the sale of this product, which bears his signature.
