Frequently asked questions

The Haimont Kids' Vest has a 3L capacity with 8 pockets, perfect for two 250ml soft flasks, snacks, and adventuring gear for little explorers!

We don't recommend bladders for kids. Simplicity and safety are top priorities. Soft flasks are the perfect, kid-friendly solution.

Not at all! It weighs only 135g, which is very manageable for children. The 3L capacity also prevents them from carrying too much.

It’s proportionally smaller, lighter, and ergonomically shaped for kids’ torsos, ensuring better comfort and stability.

Yes! Its lightweight and high comfort make it ideal for short hikes and kids' trail races, promoting fun and self-reliance.

With adjustable side straps, it can grow with your child, typically lasting 2-4 years. They'll outgrow it before they wear it out!

It's not designed for poles. For kids who need poles, we recommend a larger vest like our 5L model.

When fitted correctly and loaded properly, it will not negatively affect running form and may even help promote good posture. An ill-fitting or overloaded pack will cause problems.
