"Wore it for a 50k in the Alps. Zero bounce, poles slotted in and out without breaking stride. Best vest I've owned."
"The two flasks are the perfect size and easy to squeeze back in on the move. Phone pocket actually fits my Pro Max."
"Fits a woman's frame properly — sternum straps are properly adjustable, no chafe over 5 hours. Weighs nothing."
"Carried a full mandatory kit for a mountain marathon and still had room. Mesh back kept me cool in the rain."
"Simple, well made, no gimmicks. The bungee on the back is genius for stashing a wet jacket mid-race."
"Ordered the blue — looks even better in person. The 60-day exchange made picking a size stress-free."
Yes — two 500 ml BPA-free soft flasks come with every vest. The vest is also compatible with 1.5 L hydration bladders (sold separately).
Size S fits chest 32–36", M fits 36–40", L fits 40–44". If you're between sizes, size up for layering. The 60-day free exchange means you can swap risk-free.
No. The 4-way stretch construction and adjustable sternum straps keep the load locked to your torso even loaded with 10 L of gear.
