Consolation & Match
Whereas we cherished the environmentally accountable use of 100% recycled supplies within the Dyna and Duro, we discovered the material to be considerably tough on uncovered pores and skin. Whereas it’s not a difficulty on most runs, it would current an issue on scorching days when working shirtless.
We discovered the plastic rail for the sternum adjustment to be versatile, that includes a snap-in twin chest strap system, nevertheless it was stiff and rigid, which made it a bit uncomfortable.
Moreover, we discovered the clips to be considerably fussy to make use of. We appreciated the ladies’s particular design of the Dyna however discovered it to run small, making it troublesome to get the pack clipped when it was full. Some runners could wish to think about sizing up, particularly in the event that they’re measuring near the higher restrict of a measurement.

Performance
We had been really impressed by the easy-access pockets of various sizes whereas on the transfer. All our necessities, like gels, salt tabs, cellphone, and gloves, had been readily accessible throughout our actions.
Throughout a multi-hour tour, we by no means needed to cease to seek for a snack or salt tabs. A full-size zipper pocket saved our cellphone safe.The slip-in clip for the hydration reservoir was easy to make use of, making refills straightforward.
Nonetheless, we felt the absence of a clip or magnet for the hose. With out it, we needed to tuck the mouthpiece right into a pocket whereas transferring to forestall it from bouncing round.
The hydration sleeve may additionally profit from some insulation to maintain warmth from transferring to the included run-specific 1.5-liter reservoir from our physique.
We additionally appreciated the attachment factors for trekking poles and an ice axe, in addition to an included security whistle, which makes this a flexible alternative for mountain adventures in addition to path runs.
Efficiency
We discovered the efficiency of the Dyna to be missing in safety. Regardless of adjusting the sternum straps, we couldn’t stop the pack from shifting upward within the entrance as we ran. We regularly tugged it down, which distracted us from having fun with our run.
Moreover, we seen that the pack bounced excessively throughout our runs. The bladder’s straightforward clip system, whereas fast and easy to make use of, didn’t hold the reservoir in place. The highest of the bladder bounced and sloshed it doesn’t matter what changes we made.
Once we swapped flasks for the reservoir, we considerably decreased the bouncing and shifting. For runners preferring a flask system, this vest could carry out nicely.

The recycled supplies that comprise the Dyna and Duro are thicker than most working vests accessible, leading to an exceptionally sturdy vest.
We discovered that the stretch mesh pockets have loads of give for stuffing gear and snacks, but they continue to be formed and don’t stretch out of shape regardless of repeated use.
The thicker mesh can also be puncture and snag resistant, making it a dependable vest for trails the place obstacles could pose a problem. If you happen to’re trying to find a long-lasting, versatile working vest that may deal with each lengthy days and shorter runs, this can be the pack for you.
Breathability
The downside of the thicker, extra sturdy cloth is a lack of breathability. The Dyna/Duro was the least breathable of the packs we examined, taking longer to dry and vent warmth than the others.
We discovered the pack to really feel a bit heavy from water retention on lengthy wet runs within the Pacific Northwest, nevertheless it wasn’t a dealbreaker, despite the fact that the material did chafe considerably when moist.
That mentioned, we found that the 3D airmesh bodywrap building offered sufficient air flow even throughout intense runs. Whereas this vest is probably not cool sufficient for runners in extraordinarily scorching and humid climates, it should present glorious worth for many runners.
