Frequently asked questions

The 5L is minimalist. The 8L lets you prepare for more variable conditions.

Key differences:

  • ​​Capacity:​​ The 8L adds space for an insulation layer, robust rain gear, and extra food.
  • ​​Hydration:​​ The 8L has a dedicated bladder sleeve (for 1.5L-2L), allowing a flexible "front flasks + rear bladder" combo.
  • ​​Use Case:​​ 5L is for 10-25km. 8L is for 20-50km or races with mandatory gear.

The Haimont 8L vest is perfectly matched for 20km to 50km trail races, comfortably holding all required mandatory gear and personal nutrition.

Yes! This is a core advantage. It features a separate internal hydration sleeve and two front pockets for soft flasks, offering ultimate hydration flexibility.

The vest itself is only 235g. For shorter distances with a light load, it feels similar to a 5L. For long runs, it's what lets you run safely, steadily, and longer.

It features a smart, multi-compartment design:

  • ​​Front:​​ Soft flask pockets, gel pockets, zippered secure pocket.
  • ​​Back:​​ Separate hydration bladder sleeve, main compartment for safety gear.
  • ​​Sides:​​ Stretch mesh pockets, zippered security pockets.
  • ​​Exterior:​​ Loops and straps for trekking poles or gear.

Absolutely! It features a highly efficient front quick-attach system for trekking poles, allowing you to deploy or stow them in seconds without stopping.

It uses 3D honeycomb airflow technology. This mesh is more breathable and reduces sweat buildup by 40% compared to traditional fabrics, keeping you cooler and drier.

It's a perfect two-in-one choice! It lets you "train as you race" by practicing with a similar load. Come race day, it effortlessly carries all your mandatory gear.
