What's the main difference between the 8L and 5L vests?

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.

What distance is the 8L vest best for?

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

Can the 8L vest hold a bladder AND soft flasks?

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

Will the 8L vest be too heavy and slow me down?

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.

What storage compartments does the 8L vest have?

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.

Can the 8L vest secure trekking poles?

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

Will the 8L vest be too hot in summer?

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.

Is the 8L vest good for both training and racing?

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.

Lightweight hydration vest praised for comfort and ample storage. Customers said it stays secure without bouncing, with many pockets for essentials. Includes water bottles and optional bladder. Some noted sizing runs large, especially for smaller runners. Flask openings may be narrow for ice cubes. Overall excellent value.

Good

I love this vest. There is just a couple issues. Defintly can't wear just my sports bra. It has rubbed me raw in just a couple places. The place for my phone is not quite large enough. it makes my phone dig into my rib cage. So i just wear a belt to put it in. Also, when the water bags are full, it's hard to put stuff in the pockets. You can, it just can't be that big of an item. I love the fact I can drink from them without taking them out. The trash can is a cute idea, but I never use it. To unzip pull it out and put trash in it while trying to run is a little bit too much. I don't like it hanging off the side either. I will be using it for my marathon

Well Made

I bought this as an avid trail runner - averaging 46 miles a week.

It fit me a little loose up top - I grabbed a small per their size chart, their support team was really great and helped get it resolved.

The vest itself is well made, I think it’d be really great for long hikes and long distances because of how much it can hold.

With MY short experience I wouldn’t run in it just because of the fit - but every body is built different so it may work for you.

It is a comfortable vest -

Thank you so much for taking the time to share such thoughtful feedback!
We also really appreciate your honest feedback about the fit. Every runner's body and fit preference is different, and your experience is valuable to us as we continue improving our vest designs.
We're happy our support team could help, and we hope to have the chance to serve you again!

Perfect for my race

I was surprised e how many pockets it had that I didn’t realize when I purchased it. The back pocket is great for larger things. Works extremely well and have been wearing it ever since.

Enjoy the pic of me and pup about to go for a trail run wearing my vest!

Awesome Running Vest

Extremely light, perfect for long runs. It covers your back really good and it does not rub bounce too much when running downhills. 100% recommended.

This would be a great option for runners or whoever needs a slim and lightweight hydration pack.

Awesome Running Vest!

Lightweight and functional. Used this pack while backpacking/hiking the Sheltowee Trace Trail. Lots of pockets and a water bladder, too. Great color and quality.

I love this for my long runs. It holds my water, gels, keys, and phone easily while not bouncing too much. Easy to adjust, very light and comfortable.

Great Hydration Vest

I've used a lot of hydration vests since they've become popular. As much as I've liked my Salomon and Osprey vests, I prefer the Haimont 8L vest. You can't beat the price, plus it's lighter and fits better. The pockets are easily accessible and carry everything I need. The only negative is that the soft flasks it comes with have openings that are too small, in my opinion. But I just use my Salomon soft flasks with wider openings. I 100% recommend this hydration vest and would buy it again!

Great budget option!

Honestly a great option for not too steep of a price. Came with two front-pocket water pouches/bottles. Swapped them out for some long straw ones which fit perfectly in the vest. Ran a couple 12k with it and it was comfortable, plenty of pockets to store your belongings and I appreciate the little trash pouch to keep sticky energy gel packets from making a mess.

Great vest

Light weight and comfortable. Lots of pockets and nice customizable fit. My first time trying Haimont product and I would buy it again.

So good I bought a second

Love this running vest! This is my second one because I wear it often! It is perfect for long or short runs.

The vest is nice and lightweight. I've used it on several trail runs where I just need some water and some chapstick. My only problem with the water bottles that come with it is they are so small in the lid area you can't put anything but crushed ice in the flasks, they are too small. Suggest making the flask openings normal sized to fit an ice cube, no one likes warm water. Otherwise it's okay so far.

Thank you for sharing your feedback! We really appreciate your suggestion. Our product design team is already working on an upgraded version, and we're planning to introduce flasks with a wider opening soon. Stay tuned!
