Unleash Your Ultra Potential with the Ultraspire Zygos 5.0
As a seasoned ultrarunner, I’ve explored various race vests, and for Tahoe 200 (which I ran in July 2023) I decided to try out both the Ultraspire Zygos 5.0 and the Big Bronco Race Vest. The Zygos 5.0 stood out for me as a high-capacity vest designed for the long haul, I’m talking 100miles+.
Comfort and Stability: 4.5/5
The lightweight and comfortable wrap-around design, coupled with the ErgoFit Harness, creates a stable and hindrance-free experience. The MaxO2 Form adjustable closure system is a game-changer, allowing the pack to conform to the body with a single pull. This was pretty handy especially during training when I had the vest packed at various levels, sometimes with anything barely in it so I did a lot of adjusting. Even during intense runs, this vest remains secure without affecting my natural breathing.
Pockets Galore: 5/5
One of the standout features is the impressive array of on-the-go pockets. The 2 zippered shoulder pockets, dual 4-way stretch mesh pocket, pair of stretch mesh pockets (including a zippered one for a large cell phone), a zippered side pocket, and a magnetically closed side pocket offer unparalleled organization. The main back compartment, reinforced with XT fabric means its super durable.
Versatility and Functionality: 4.8/5
The Zygos 5.0 proved its mettle during my recent challenge, the Tahoe 200 in July 2023. The ability to separate my kit in various pockets was a lifesaver when fatigue set in. The inclusion of bungee cords allowed me to secure a jacket when my pack was full, showcasing the vest’s adaptability to dynamic race conditions.
Reservoir and Size Options: 5/5
The 2-liter reservoir is neatly housed in the removable insulated bladder compartment, should you need to use a bladder. I used the bag with 2 soft flasks with straw attachments. This set up took a bit of trial & error I ultimately went with the soft flasks with straws using the mag clips as an additional support to stop the straws flapping around.
With three size options, Ultraspire has made it easy to find the perfect fit for any body type.
Personal Experience: 4/5
Personally, I found the Zygos 5.0 to be super functional, earning its spot as my go-to bag for the Tahoe 200. However, I experienced some chafing on my mid-back area and sides (love handles), which is worth noting for fellow runners. It’s a reminder that even the best gear may require some trial and error to find the perfect fit.
Final Verdict:
The Ultraspire Zygos 5.0 is a standout in the world of high-capacity race vests. Its thoughtful design, plethora of pockets, and comfort make it an ideal choice for ultrarunners tackling challenging races. While personal comfort experiences may vary, the Zygos 5.0 is undoubtedly a reliable companion for those seeking a balance of capacity and functionality.
