### ⭐⭐⭐⭐⭐ Best Pack I've Used - But the Liner Does Rip Out
*by A***S on August 15, 2021*

I have been ultra running for years and have always been loyal to the Salomon Skin Set 12L packs. But I recently ran a mountain 100M that had a ton of required gear and very long, unsupported stretches. I couldn't fit everything in the 12L so with the recommendation of a fellow racer, I upsized to this pack. Now its the only thing I want to wear. I'm small framed and was able to adjust this to 0-bounce, no chafing, and nicely distributed weight. The pockets are intuitive so it's easy to stash what you need where you need it. And the straps on the back work nicely as bungees if you want to loop a wet jacket or puffy through them. The pole holders keep the poles off your back and in place. And all the secret pockets add a nice touch - I'm thinking specifically of the protected phone pocket, and the extra pockets I use for trash in the side food pouches. Only complaint: The foil insulation lining in the bladder compartment ripped out of my blue one on the second use. I sent it back to Ultraspire and exchanged it for a new one. The foil lining ripped out of that one on the first use. It's an unnecessary feature, but it was a bit frustrating. I have talked to others with this pack and it's 50/50 whether the lining survived. Since everything else about the pack is above-par, I'd highly recommend it. It's now my go-to piece for adventure running.

### ⭐⭐⭐⭐⭐ New vest
*by L***L on July 1, 2023*

Absolutely love all the storage & the fit. Really great for long runs. Ordered a second one for my wife.

### ⭐⭐⭐⭐ Great pack for the money
*by Y***  on December 10, 2019*

I purchased theUltraspire Zygos 2.0 as a replacement for my aging Camelbak ultra pro. So far I’ve only ran about 75 miles with the pack. The Zygos 2.0 fits great ( I’m 5’8” 155lbs pack size medium) no bouncing or rub spots. Front and side pockets are great and easily reachable. Bottles are easy to get in and out of the front holders. Plenty of room to store gear for long runs and ultras with long distances between aid stations. Zippers pulls take a little getting used to, but work well. Only thing I wasn’t impressed with is the 2 liter reservoir that comes with the pack. It works fine, but I like the bite valve on the Camelbak much better. It also seams to be a bit hotter to wear than the Ultrapro. The Zygos 2.0 seems to be well built extremely well and should last for a very long time. Great pack for the money.
