Fast-Pack

This is a great pack if you are going to run 20+ mile self-supported routes. It rides quiet on your back without having to have a waist-belt. Side pockets are large enough to hold extra water bottles. Back pocket is large enough to hold an extra jacket-layer, and there's still plenty of room for snacks. The only complaint I have is that the breathable mesh used for the back panel sometimes chafes my skin if it's in direct contact with my skin. It's lighter weight than most other packs in the same category though, and because it rides without bouncing around (and no need for the waist belt), I prefer it to other comparable packs by competitors (Osprey and Camelbak).

Good pack but needs work

Overall a pretty good pack. I like the volume of the pack; good enough for a long day's run; plenty of pockets. Because I hate having a belt around my waist on a pack, I really love the vest concept. Doesn't bounce or cause any undue stress. Rides really well.

However, as others have mentioned the pocket for the hydration bladder is in an awkward position that makes removing/placing the bladder with a full pack next to impossible. Would be better if the hydration bladder pocket was either on the outside or the position of the main compartment zipper was a bit higher up on the pack for easier loading/unloading.

The other criticism I have is with the bladder itself. Sorry but it's too complicated! I like the concept but in practice I think it's just too messy and awkward to use. K.I.S.S.

Other than that I really have enjoyed using this pack for the past couple of years including several ultra marathon training runs and races as a member of the Wasatch Speed Goat Mountain Racing Team. This was my go to pack during my speed-hike of the 335 mile Pinhoti Trail a couple years ago.

Responded on

I use a smaller bladder and have bagged the one that came with the pack. I tote extra water in the form of water bottles in the side pockets to make up for using a smaller, 70 ounce bladder.

Light Weight, Good Fit

Nathan makes some of the best endurance packs out there. They are light and tuff. When I picked up my first pack (Nathan 020 and carries 70 fl oz of liquid) I was worried about the construction of the pack as it appears that it won't take the beating of all day riding/racing. I used the pack all fall on long rides and raced with it this winter without flaw. The pack still feels and looks new. Excellent front stash pockets making gels and electrolyte accessibility easy. The pack is kind of like a fishing vest that is fit for your body with the adjustment straps to cinch down the play in the pack. The pack sits nice and snug without any play or sway. The Synergy pack is a bit big for most of my endeavors but built for the trail. If you are looking for a smaller tighter pack look at the Nathan 020 and 008. The 020 is a smidge bigger than the 008. These are perfect for 6 hour rides and races. Ride On.

Good pack, very comfortable

I needed a slightly larger hydration pack to carry more gear during extended trail runs (more than 50 miles). After looking at several different packs I settled on the Synergy mainly because I liked the idea of no hip belt and the inevitable rash I get from them..
I took it out for an 18mi "test run" and was very pleased. I read the other review about the poor location of the bladder compartment and while I do agree it is high- if you fold the top of the pack over you can pull the bladder right out. I timed how long it took to pull the bladder, fill both fluid chambers and put it back in the pack and it was around 1.5min. No too bad. The dual chambered bladder is a great idea and I really liked having a water or electrolyte drink option. It did take a bit to get everything dialed in so that the pack did not bounce around. Even then the fluid did slosh around in the bladder but no more so than any other 100oz pack that I have used. After about an hour of running the pack settled in and was quite comfortable. The main storage compartment is large and the pockets on the shoulder straps and sides of the pack are well placed and hold a lot of food. This pack would be good for extended, non-supported trail runs or even 12hr adventure races. Overall I am very pleased with this pack after its first test run.

Serious Flaw in Design

Nathan makes excellent race vests and I regularly use the Zone 2.0 for ultrarunning. But the Synergy pack has a serious design flaw with the hydration pocket. It is nearly impossible to remove and replace the bladder into the pocket because it is cut way too high and is poorly located inside the main part of the pack instead of having an outside zipper access. This would be a major frustration during an event and even at home when loading a filled bladder into the pack. Otherwise it has all the great Nathan features. Needless to say, I did not keep this pack.
