Hài lòng, phù hợp cho cự ly 21km-42km

Cự ly từ 21km trở lên là bắt buộc phải có vestt nước. Tìm hiểu vest các hãng khác mà đắt quá, được b bè giới thiệu đến đây mua thấy rất hài lòng về chất lượng cũng như mức giá sản phẩm của Decathlon. Tôi mang đc 1,5l nước với vest này. Không gian đằng sau vest có thể đựng được áo mưa..., không gian đằng trước đựng điện thoại, thanh năng lượng,... rất tiện. Điểm cộng nữa là các dòng vest tại đây trang bị sẵn còi báo hiệu, rất tinh tế đến từ nhãn hàng


Chào anh Hưng,

Xin cảm ơn anh đã tin tưởng chọn mua và dành thời gian để đánh giá, chia sẻ trải nghiệm của mình về chất lượng sản phẩm của Decathlon

Hy vọng Decathlon sẽ luôn được phục vụ chị trong thời gian tiếp theo. Chúc chị và gia đình thật nhiều sức khỏe.

Vest nước tốt với thiết kế khoa học

Mình đã sử dụng vest này được hơn 1 năm. Mình cũng không phải là người thường chạy trail nhưng cũng đã bắt đầu chạy nhiều hơn khoảng 6 tháng gần đây. Mình cũng thường dùng vest này làm balo mỗi khi đi chơi hoặc đi leo núi trong ngày. Đặc điểm: 1) Gọn và nhẹ 2) Thiết kế ôm sát người nên đi bộ hay chạy bộ đều rất thoải mái 3) Giá thành rất rẻ so với thị trường 4) Có tất cả ngăn cho đồ của mình --> dt, sạc pin, ví tiền, áo khoác nhẹ, đồ ăn nhẹ và chưa được hơn 3L nước

Good product Value for money

Thanks for the lightweight and the ergonomic design. I have used the back pack for hiking and running several times as if I was carrying nothing on my back. The materials of the back pack keep the proper body heat dissipation in humid and hot weather. Value for money. Credits go to the design team.

Running vest/pack

So far this has been perfect. It is generally comfortable and has all the right pockets for shorter and longer runs. However, it is not perfect. These are the niggles I have had so far; 1. Trying to put two full 500ml soft flasks in the designated pockets can be a challenge. 2. No instructions. I did come across a link with a video before purchase but not been able to find it since. It should be on the product page. As a result of this it can be difficult to know how the water bladder tube should be set up. 3. It is suggested the drinking tube can be cut shorter but trying to detach it from the bladder will be no mean feat. 4. The rear stuff pocket appears to have a weak stitch which I wonder how long it will last when stuffing a running top into it. 5. The drinking tube has a PVC bite cover. No details about how long they will last and if replacements are available. Same applies to the soft flasks.

The perfect pack for Ultra-running

This ultra-pack does what is says on the tin. Designed by ultra-runners, it stands out against its competitors and offers a great pack for a great price. The 10.5L volume is double the volume of most packs. The vest-like build moves away from straps that can often feel uncomfortable over longer runs, the 1L bladder is a perfect size and has 2 pockets for 500ml standard lucozade bottles. In fact it has so many pockets, including internal safe pocket, big external coat pocket and a great front pocket for phone and charger. Sure, the bag isnt waterproof, but this wasnt a bit issue for me, as you can easily wrap in a zip back. A great buy, highly recommended.

Great bit of kit

Really comfortable to run with and had plenty of storage for those longer runs. Feels well made too.

Good value for money

Overall no real problems, I've used it for a few long runs and a trail half marathon and it's done the job effectively. Good price compared to some others I've seen. My only complaint is that the straps sit a bit high so the water tube is a bit higher up than I'd like, but it could well be that I've not adjusted it properly.

Spot on

This is my first running vest so have nothing else to compare. However, i’ve used it now a few times and it is spot on. Fits loads of stuff in, stacks of pockets to choose from. Fit’s perfectly as 3 adjustable straps at the front. I’ve had no problem at all with any rubbing etc and have completed hours in it. Would highly recommend and wouldn’t see any reason why you would buy the other very expensive brands.

Excellent bit of kit

Great fit, excellent storage with plenty of room for everything you need to carry with you . Felt really good while I was running, not constricted around the chest like some I've tried previously. No problem in recommending this pack.

Too fiddly and no instructions

This might be a great product but for some reason no instructions are provided of how to fit it together, fill it, etc, so you just end up fumbling around with it for ages before your run. The zipped picked is almost impossible to access when the bladder is full. Hard to think of any reason why it doesn’t come with instructions.

10 litres and 10 pockets to carry your essentials on a trail run.

There are 6 pockets at the front so you can reach your essentials in a single move:- 2 pockets for 500 mL soft flasks- 4 mesh pockets for gels, bars and collapsible beakerThere's a secure pocket at the back to store your valuables (smartphone, keys, survival blanket), a main pocket to store your clothes and headlamp, and a big mesh pocket to keep your rain jacket always handy.

A bag designed to keep you hydrated on trail runs

With space for a 1-litre water bladder on the back (included, attached by hooking on) and 2 front pockets for 500-mL flasks, this bag allows you to carry up to 2 litres of water in total.Considering that you drink an average of 500 mL of water per hour while trail running, that gives you 4 hours of autonomy. Enough to give you peace of mind between aid stations!

So, what about the water bladder?

Your bag comes with a one-litre water bladder included. It's suitable for temperatures ranging between -20 and +40°C, for water: no milk, no alcohol, and no putting it in the microwave ;)As to the tube, you can cut it to whatever length you like!

A bag so light you don't even notice it

In trail running, every gram matters! Weighing 285 g when empty, your bag is truly lightweight.And to fit your personal requirements, it's available in 3 sizes (XS/S, M/L, XL) and is easily adjustable:- You can choose the height of the 3 front straps- Thanks to its 2 side elastics, the bag stays so stable you'll forget you have it on when trail running

A design loaded with details, to make your life easy

Trail running puts you in situations of extreme fatigue. That's why we've designed a bag that makes every move easy.- The water bladder tube is clipped on, so as to remain near your mouth at all times.- The mesh pocket at the back allows you to reach your rain jacket in one move.- The 110 dB safety whistle is incorporated into a front pocket.

Never run without your poles?

Along with the whistle - mandatory in many races - which is located in the little chest pocket (hence near your mouth!), this bag also features 2 elastic straps on each side to attach your 3-section trail running poles.

Gaëtan, kalenji product manager, introduces his team of trail running enthusiasts:

"For us, it's a matter of pride to design and test our products ourselves. We wanted to make a bag we'd be proud to wear. I took part in 6 or 7 trails last year from China to the OCCⓇ in Chamonix.
