Why we love it

Main Highlights

[ALL-IN-ONE STORAGE WITH INCLUDED 500ML FLASK] Balanced multi-pocket design keeps essentials secure and within reach. Front pockets fit your phone, flask, and energy gels, while side pockets store keys, AirPods and small items without bounce.
[SECURE BODY-FIT] Designed with 2 chest buckles and 2 waist adjustment straps to enhance body contact and reduce movement. Removable chest buckles allow customizable positioning for a closer, more secure fit.
[3L REAR STORAGE – 2L BLADDER COMPATIBLE] Spacious back compartment fits a windbreaker and up to a 2L hydration bladder (not included). Dual compression cords help secure items while moving.
[TRAIL-READY SAFETY & PRECISION FIT] Trekking pole holders and reflective details ensure secure storage and low-light visibility, while the built-in whistle adds essential outdoor support. Designed for a stable, bounce-free run, this vest is available in two sizes: M-L for 77–95cm (30–37in) chests and L-XL for 90–110cm (36–43in) chests.
[LIGHTWEIGHT & ZONED BREATHABLE DESIGN] Approx. 172g (M-L) and 186g (L-XL) for a reduced load during runs. Ventilation fabrics are optimised by zone: 20mm honeycomb mesh on the back helps reduce contact area and heat buildup, 2mm air mesh on the chest improves airflow, and 1mm air mesh on the front storage pocket maintains structure while helping limit item visibility.
