ARCh MAX Hydration Vest 6L w/ Soft Flasks FAQ's
Everything you need to know about ARCh MAX Hydration Vest 6L w/ Soft Flasks.



The ARCh MAX HV-6 is a 6-liter trail running vest designed and manufactured in Spain for short to medium distance training runs and races. It features an ergonomic body-hugging fit, pull-handle pocket access throughout, and comes with 2x 500mL soft flasks included — ready to run the moment you open the box.
It depends on the colorway you choose. The Feed Branded variant includes 2x The Feed 500mL Soft Flasks. The Blue, Gray, Black, and Red colorways include 2x ARCh MAX 500mL Soft Flasks. Either way, your vest arrives flask-ready.
Two liters less storage is the obvious difference, but there's more to it than that. The 6L is the faster, lighter option — better suited for half marathons, shorter trail races, and training runs where you don't need to carry layers or extra gear. The 8L adds trekking pole holders and slightly more rear storage, making it the better call for longer efforts, ultras, and big mountain days where extra kit matters.
The HV-6 rear panel features double mesh construction for friction protection — a meaningful detail on runs where pack movement and chafing become a factor over time. You also get a large upper back pocket with security closure, an ergonomic lower back pocket, an additional zippered pocket, and a rear reflective strip for low-light visibility.
Measure your chest circumference with your arms relaxed at your sides. XS is under 30 inches, S/M fits 31 to 35 inches, L/XL fits 36 to 41 inches, and XXL fits 42 inches and above. The adjustable chest strap and ergonomic technical lycra construction — made from 100% recycled polyester — means the vest moves with your body rather than shifting against it on technical terrain.
