Best value running vest (in my opinion)

For the past 3 years, the 10 litre version of this vest has been my go-to running vest - used on a weekly basis without any signs of wear and tear offering everything I needed for runs up to 6-hours duration, offering plenty of room for wet-weather clothes, food, drink, and all manor of extras including gels, phone and other essentials. Looking to go that little bit further and bogged down with mandatory kit requirements, I naturally tried on the 15 litre version and wow - this adds a lot more to almost every element of the pack. All of the best parts of the 10 litre version are still there but with way more space in the rear for bulkier items with adjustable side straps so nothing moves around when carrying a lighter load; more side pockets with adjustable side straps to get that perfect fit, whatever gear you are wearing; dedicated front phone pocket and two smaller pockets on the back which can fit a surprisingly large number of bits and bobs for easy access. I've never used the rear water carrier but it's a nice option to have and will be useful for waking in the summer and the magnetic tube holder is a nice touch. The blue version of the pack also has attachments for collapsible walking pole quiver - an optional extra which I almost will certainly buy next paycheck. There may be technically better running packs on the market, but you'll struggle to buy a better quality pack without paying a significantly higher price - seriously, this is a very good pack and if it lasts half as long as the previous vest, I'll be very happy indeed.

15L trail pack

Great trail vest with more than enough room for kit, food, first aid kit, map and even a small thermos for colder runs/treks.Easily as good quality as the more expensive top brand trail vest producers and for half the price.

So far so good

Used this bag on my first trail ran and put it through its paces on 21 mile slog through the cotswolds. I’m impressed with the storage had all the space I need for the days run. The front storage is easy to access for when you need to access a snack but don’t want to stop. On one issue with bag is it’s too loose fitting. I found I could only fill the bladder to about 1 litre before the extra weight made the slip down my back. I bought the L/XL size and it’s a ok fit when I tried it on instore. But out in the real world when I’ve loaded my kit and added water I would have appreciated a snugger fit or more straps to tighten the fit. I would recommend asking the staff if you can pack some kit into and possible a filled bladder to try fit when it’s filled up. That way you get a understanding of the size you need. That aside. If you can find a good size for your body type, I recommend this bad. It’s a really good price for the all the space you get. I ran 3 1/2 hours in it and aprt from the sagging issue. It was very comfortable to wear, no chaffing on my shoulders or back. Also it was very breathable.

A good backpack

The pack is spacious and fits everything you need for an ultra. I love the number of pockets for stashing salt tabs etc and the pack sits well on my back with no movement. I have used mine on several long runs and I found it comfortable to wear, no chafing even after 50 miles. Could it be improved? Maybe a bit of colour coded beading around the front pockets to help me remember where stuff is stashed but other than that it is very good.


Feels like I'm wearing nothing at all! The whole bag is well fitted and becomes part of me. There is a pocket for everything I need as well as extra. I even take this on shorter runs now as it's so easily carried. Perfect for trails, hikes and road runs.

Running bag review

Overall this is great value bag. It is comfortable and it has lots of pockets and loads of space for carrying gear that you might need. The straps at the front can be at various heights which is great. I had to get an XL for it to be comfortable (I am normally medium to large) so I would recommend going to the store rather than ordering online. The only issue I have had with it is running with soft bottles (I prefer them to a bladder). The soft bottles are held in their pockets by elastic at the top rather than adjustable cords. The elastics make it harder to put the bottles back in after drinking. An adjustable cord would allow the bottles to be returned to their pockets much more easily. However, given that this bag is less than half the price of anything else with that capacity, it didn’t put me off purchasing it.

I purchased this in preparation for a 50mile ultra race next summer. I’ve used on a couple of 20-25 mile runs so far and it’s great. Comfortable and lots of space

Good item but..

Good vest fully loaded but the straps on the buckles need to be longer. That said it is very quality and very versatile.

Evadict 15L running vest

Excellent product. Tested repeatedly speed-hiking, mountain running, & scrambling in Snowdonia (Snowdon Horseshoe, North Ridge, Watkins Path, Tryfan, Glyders), & The Lakes (Helvellyn). Only gripes being: The cinching side straps sometimes loosen during fast steep descents. The mobile phone chest pocket could be a little larger to accommodate the larger iPhones (in protective cases).

Gaëtan, the evadict product manager, tells the story behind the 15 l ultra trail running bag:

We wanted a bag that'll take you to the end of your trails in complete safety and that can carry all your mandatory gear. We took our customers' opinions into account, for instance adding the smartphone pocket.We designed it for ultra trail, the most demanding category there is. Then we did two series of protocolled tests, which yielded excellent results.We're proud of this product, we spent a lot of time working on its stability, compartmentalization and accessibility.
