Synaptic 2.0 Waist Pack

(11 customer reviews)

$59.95

The Synaptic 2.0 waist pack is highly versatile and ideal for most training runs and races. The versatility comes from access to all compartments without taking the belt off. This pack provides the ability to carry hydration, nutrition, home essentials, and is equipped with Z-pole attachments all while remaining very lightweight when loaded down. The original Synaptic was Ultrarunning Magazines’s Top Pick for stability; the Synaptic 2.0 features the same weight distribution ratio and conical belt shape but with upgraded functionality. This pack comes with an UltraFlask 550 Hybrid Bottle in the holster. This bottle is simple, intuitive, and the construction allows for easy access to remove or holster the bottle on the go allowing for a more regulated hydration schedule. This pack features a mesh zippered pocket and additional quick stash pocket on the side of the holster. The front 4-way stretch mesh pocket has capacity for a large cell phone but remains flat even when fully loaded. Shock cord attachments on the front give you carrying options for Z-poles or layers of clothing you want to carry with you. One size fits most.

    I would like to start by saying that I have avoided using waist belts/packs for a long time. I tried one out a few years ago and what I disliked most about the experience was that I felt like I was fighting with the gear the whole time. It did not feel natural at all.

    I decided to take a chance with the Synaptic 2.0 because I needed something for my shorter training runs. I have used handheld bottles for years, but prefer to be hands free. At first, I was a little concerned because I was not used to the feeling of a bottle resting against my lower back, something that I found particularly noticeable when standing still. But I was pleasantly surprised when I didn’t really feel a thing once I started running.

    In terms of fit, this waist pack is amazing. The dual adjustment straps ensure that I can get a comfortable, even, and natural fit. The pack feels super secure with no bounce and the way it molds to the body almost makes you forget that it is there. I think it also worth mentioning that I didn’t really have to adjust the straps once they were set.

    In terms of storage, the zippered mesh pocket is large enough to fit a drivers license/cash/card/key comfortably. I was also pleased that the front pouch could hold my phone and still keep a low profile. I even managed to fit 3 gels in with the phone with no issue. Inevitably on short training runs we’re often forced to make choices on what to bring and what to leave behind. I really love that the Synaptic 2.0 is versatile and gives you more options to consider when it comes to carrying capacity.

    I like that the bottle is very easy to holster and that it remains static throughout the run. Bottle removal, however, is user dependent…everyone will likely have a different method based on what is most comfortable for them. I find the easiest way is to grip and pull from the top with one hand while pushing the bottle up from the bottom with the other simultaneously.

    In an effort to be transparent, I have not (needed to) use the quick stash pocket on the outside of the holster (yet). This is likely because I prefer that my “workspace” remains in front, but I can see how this pocket would be useful to store empty gels packets/trash until you can dispose of it properly.

    All that said, I am very happy with this product and am excited that it is part of my gear lineup. I think the Synaptic 2.0 is a fantastic option for those looking for a hands-free, high capacity solution for shorter runs and races.

    The first Synaptic was the first waist pack I’d run with where I did not experience any bounce when the belt was adjusted properly. I wore that belt for the first 50 miles of the Wasatch 100 and loved the feeling of my upper body being free (especially in the heat!). I was able to tuck empty soft flasks under the belt and 12 gels in the front pocket. My main complaint about the first edition was that the belt was difficult to cinch down to my 31″ waist size, which also meant that I had a lot of extra material after pulling the belt tight and nowhere to put it. The belt also was not very flexible, and sometimes came loose as I ran.

    The Synaptic 2.0 is a huge improvement on an already solid waist belt. The belt now fits my waist size and there is a small loop where extra material can be tucked. The new materials provide some stretch without compromising on the secure, no-bounce feel. The mesh front pocket keeps nutrition and gear flatter and closer to the body, and the zipper is removed so the access is similar to the Fitted Race Belt. I now use the small pouch near the bottle to carry an extra “emergency” gel that’s easy to forget about when I don’t need it but assuring to know that it’s there when I do.

    I tested this belt at The Capstone 50k and spent the first few miles playing around with the fit, then didn’t need to make any adjustments for the rest of the race. The course is very technical, with steep downhills over slickrock, and the pack remained secure the entire time. I wore the belt directly against my skin and experienced no chafing or discomfort. The bottle stuck out the back outside of my shirt for easy access. I found it easier to remove with the left hand and replace with the right. What I was most impressed with was that I was able to carry all my nutrition and gear for the entire race in such a low profile belt! I carried six gels, gloves, and a light jacket, and only had to refill/replace my water bottle at aid stations. It was a perfect trial run and I now feel confident that I’ll be using this at 100-milers in 2020 where carrying more nutrition and gear between drop bags is essential.

    I haven’t had a chance to test the belt with a waist light but I’m curious to see how that works. I also haven’t tested the front loops with trekking poles, but I imagine the flatter profile on the front will improve the security of the poles from the first Synaptic.

    My only suggestion for the Synaptic 2.0 is to offer the option to purchase the hybrid flask separately. Anyone who’s purchased UltrAspire packs/belts in the past probably has a handful of these already!

    I highly recommend this belt for any run from short training runs to 100 miles. It’s recommended for 1-hour between aid stations, which I think makes sense. A creative solution to be able to carry more water is to carry a soft flask or two in hand that can be tucked into the belt or stashed in the front pocket when not in use.

    I needed something for shorter runs where I didn’t want to wear a hydration pack or a carry a handheld. I decided to give the Synaptic 2.0 a try. I’ve done several short runs and have to say this exceeds my expectations for a waist belt. The nylon belt is comfortable, not bouncy and easy to adjust. The water bottle is really easy to put back into the fitted pocket and I’ve found even when the water bottle is full, there is minimal jiggle. I like the minimalist feel the Synaptic 2.0 has, but still able to put a few items in the pockets if needed.

    Ultraspire hit the ball out of the park with the synaptic 2.0. The shape of the bottle plus the angle that it’s held at is the perfect position to prevent sloshing around or feeling heavy when full.
    The pockets are perfect for holding a cellphone, keys and a gel or two.
    Great for mid sized adventures that don’t quite require a running vest.

    I decided to give one more waist pack a try, have tried several over the years with no success, they all bounce so much I threw them in the closet or gave them away, Wow!!, am I glad I tried the Synaptic 2.0, the best I’ve ever tried, I almost forget it’s there, no bounce at all, able to carry everything I need , for an unassisted run under 2 hrs. The loops in the front are awesome, I wear gloves for morning runs, my hands get cold easily, but after warming up I stick them under the loops, synch them down and forget about them, a great product.

    Never ran with a belt that had hydration but as my runs become longer, I felt it was necessary. I love this belt. It is comfortable and light.

    My only issue is that it was missing a clip that keeps the end of the belt from being loose.

  7. dusty dustyn

    Absolutely 5 Star – in every way. Absolutely love it! Easy to adjust to fit. Never slips around. Can pull the bottle out and drink on the run, and slip it back in place. I never even notice i’ts there. I’ve uses the elastic ties in front to hold a windbreaker that I took off mid-run. Pouch holds my iPhone 10 (smaller size), and gel. Inner dividers mean I coldstore capsules as well. Smaller zip pocket fits large car key.

    No negative issues with it over four 10-ish mile trail runs. Bottle is a tiny bit tricky to remove from its holster, but only barely, and that probably helps ensure that it doesn’t fall out.

  9. Dallin Draney

    I love this pack for my sub 10 mile runs. Holds my phone, keys and gels plus the straps hold my light jacket when I start in colder mornings. I would highly recommend this pack.

    I bought this for my mom in AZ because hydration vests are just too hot for her daily walks and runs in the 100+ temps. She loves the fit of the waist pack–secure and comfortable and no bounce–the storage for keys and water is perfect as well–her frozen water bottle thaws perfectly but stays cool which is a huge bonus, and her hands stay free. Unfortunately, but phone pocket doesn’t fit an iPhone 11which is a huge bummer when she runs… while walking, she can put the phone vertical and it stays secure but not while running. Perhaps the next installment can be stretchier for the larger phones.

    After a half-dozen runs, this gets two big thumbs up: The Synaptic 2.0 is deceptively roomy. I’m able to cram 5-6 gels using the back zippered and elastic pockets, and I could put another 4-5 in the front pouch if I don’t take my phone. Also, I’m not sure how hard folks are trying to get their iPhone 11s in the front pouch. It absolutely does have enough room for my iPhone 11. I don’t use trekking poles, but I’m sure the front bungees could handle them with ease. I use them to strap down a rain or wind shell. Most importantly, there’s no bounce on the bottle holster (assuming you’ve cinched the belt snugly), which is the real reason I was in the market after years of disappointment from UD and others. The holster will accommodate smaller bottles as well, as I’m able to holster my Nathan 12oz-er in there without hassle. The one downside on the Synaptic is the bottle spout — be careful when drawing from it. It’s aggressive, and if you turn it upside down you’ll lose a couple of ounces before the spout seems to seal.

    The success of this model has me eyeing the Speedgoat for two bottles. Nice job, UltrAspire.
