A 5 L Evadict trail bag ready for your first trail runs or short-distance trail runs
To assist you on your first trail runs, our design team developed an all-in-one bag that is simple and easy-to-use: - Available in a single size, it can be adjusted to fit you with its adjustment straps and its ergonomic shape. - Your bag is supplied with a 1-L water bladder and a rescue whistle so that you have all the mandatory trail running equipment you need close at hand. - The information leaflet on the bag gives you advice on how to prepare your equipment.
Rescue whistle and water bladder information
The rescue whistle and water bladder are an essential part of a trail runner’s equipment. So, to make preparation easier, they are already included in your 5 L bag! The rescue whistle, which can produce 110 db of sound, is in the small chest pocket, so you can reach it easily. The new water bladder has a volume of 1 L, which provides two hours of running time between drink stations.
Managing your water bladder
Your water bladder has a volume of 1 L and measures 30 x 16 cm (12 x 6"). Its tube equipped with a bite valve is 100 cm (40") long so that it can be adapted to all body sizes. What you might not know is that you can easily cut the tube to the length you want for greater running comfort! Finally, we recommend that you fill your pouch with water between - 20 and + 40°C. Do not use it for milk or alcohol and do not put it in the microwave oven.
How to properly pack your trail running bag
- First step: put the full water bladder in the compartment at the back of your bag. - In the secure rear pocket, you can store your keys, smartphone and survival blanket. - Place your waterproofs in the rear pocket before putting the bag on your back. - Tighten and adjust your bag. Then fasten the bite valve. - Store your windproof jacket in the easily accessible rear kangaroo pocket. - Finally, put your gels, bars and water bottle in the front pockets.
A very simple design for a lightweight running bag
Weighing only 140 g (5 oz), your 5 L bag is lightweight and comfortable for taking with you on your short and middle-distance trail runs. Its comfortable material, ergonomic shape, and accessible pockets are great for getting at your equipment more easily when running. Its adjustment straps have hook and loop tabs: you can roll them up to minimize any discomfort when running. Most of the pockets are located at the back so that they do not compress your chest.
Unique bag tested on all body sizes
To make things easier when discovering trail running, we designed this 5 L bag in one size. To make sure it fits as many people as possible, we tested it with 12 trail runners, both male and female, with different body sizes. Their advice and feedback helped us to continue improving this 5 L bag. Our Evadict team members wore this bag for numerous trail runs and other outings!

Great for the price! Used it for a hike. Not sure how I can dry the tubing when I want to store it though. I'm hoping Decathlon can provide some advice on that please!

Wow! This thing is great, I bought it because I often like bringing some things when I run but hate running with a backpack. This thing is awesome! It has a whistle, straps and compartments to hold small things. My first run today with it was great! I was able to fit my post r
un hoodie, AirPods case, and gloves in just this tiny vest! its so light weight and breathable I almost forgot I even had it on. 1000000% recommend!

Bonjour Louis Simon,Je suis contente de savoir que le sac d'hydratation vous convient. Je vois qu'il vous manque un peu plus de compartiments, alors je vous suggère fortement d'aller visiter le site Decathlon.ca pour d'autres sacs d'hydratation. Il y en a des modèles de 10 lit
res avec une poche d'eau de 1 litre, et il y en a plein d'autres.Merci pour votre retour et passez une belle journée ! Alycia de l'équipe service client de Decathlon St-Foy

La poche à eau est petite avec juste 1L mais c'est une question de préférence. Le tuyau est un peu long et raide. La souplesse du tissu fait en sorte que le poids de la poche ne permet pas de garder les sangles hautes sur les épaules et elles descendent dans le dos. L'ensem
ble en tissu se lave facilement. Un meilleur isolant entre la poche et le dos limiterait le réchauffement de l'eau par la chaleur du corps.

I am sending it back. When water bottle in it does not hold anything else really. Plus the water bottle is not stable and flys around in the bag and it has opened on my and the water spilled out everywhere! The top is open so things can fall out or when it rains things int
o will get wet . Also if you have boobs the straps down fit around them
