Like a tardis with so many options. Comfortable and forget it’s on. The bladder works well and the straps offer a flexible fit.

Bought this as my phone (Samsung a53) didn't fit in the cheaper (blue) vest phone pocket. There's a few ups and downs, but generally it's excellent! Bad bits: 1. waterproof zip on phone pocket is great, but the pocket isn't waterproof on the back, meaning you get sweaty phone. Also, I recently ran a very wet half marathon wearing the vest, and water soaked into everything. Probably not normal circumstances, but it was an extensive test. 2. As you drink the water in the bladder, the vest gets looser, meaning you have to tighten the straps bit by bit as you go. Not a big problem in itself, unless you're on the smaller side of the sizing range and the straps are tight when you start . 3. The weight of the bladder when full pulls the vest backwards, feeling like you're constantly readjusting. Good bits: 1. Good enough fit to forget you're wearing it generally. 2. Loads of pockets. Space for 2 x 500ml bottles, 2 x 150ml gel bottles, glasses, hat, sweets, headphones and food; I still didn't fill all the space. Large zip pocket on back with a small zip pocket within for valuables.

I wanted to review after my first run, but I thought I would give it a few weeks to be fair. It is a terrible pack, your water bottles bounce all over the place trying to hit you in the face especially the left hand side when you are carrying a phone as well. The chest straps slowly undo so you have to keep adjusting them. I bought the correct size according to the sizing chart but it is a really poor fit and never feels snug no mater how many times you adjust it!! The final straw was this morning when the left had water bottle holder ripped on a ten mile run the pack is a month old!! So the build quality is poor as well. DO NOT BUY THIS PACK!!!!

Can’t fault the bag overall but be careful with the hydration tube magnet attachment to hold it on to the bag as it turns out to be quite loose and fiddly and if you’re not careful it might fall off into a muddy trail and be trampled into oblivion during a race, as happened to mine in Jura! Doesn’t seem to be a spares option other than full return refund on webshop.

I run about 4-5 times with this backpack for about 100KM in total. It's very comfortable to the point I forget I have it on. The capacity is good enough to carry a couple of layers and book that I use while travelling to running location and then pack away into the bag. However, I've just noticed that one of the front elastic bands is no longer in place, and I can only thing that I snapped it accidentally. A little concerned about the durability of the product which makes me less sure about recommending it.

As my first 10l bag this appears to have all the pockets I need for a 50km Ultra. The high up water bottle pockets make rehydration very easy.

This is clearly designed for women or men with narrow waists and massive chests. It is advertised for Ultra marathon distance running. I could barely endure 5 km. The water bottles kept bouncing and trying to hit me in the face. This made running impossible. I tridled tightening all straps and cords but nothing worked . The only way to stop it doing this was to pull the vest down with my hands- meaning I could run with them. Awful. Waste of money. Will look to buy another brand of hydration pack ASAP.

Perfect for a 22 mile run in Wales! Good amount of storage that easy to get to on the go. Perfect sizing (tried mine on in store, and common sense told me to go a little bigger to account for water and the extra storage when running) Stayed nicely in place all run. I did however use my own camelbak bladder which fit in lovely.

Running my first ultra in September and had this pack recommended. Awesome piece of kit for the money - really secure when running and plenty of pockets. The large back pocket holds more than you would think with the stretchy material but still feels comfortable to wear fully loaded. Fitted all the mandatory kit for the run in the pack with a bit of room to spare.

Impossible to really size this properly as it doesn’t come with the bottles. Took it out for first run and bottles bounce all over the place, should have sized down to xs/s (if this helps anyone I’m 170lbs and 5ft8 and m/l is too big) Because I’ve now removed the tag I won’t be able to return so I’m now stuck with it, don’t make the same mistake as me.

Fantastic vest for the money

After using the predecessor model for several years I decided to treat myself to this upgrade. Almost everything about this bag is great - a phone pocket, much better front pockets you can actually stash a buff our gloves in, pockets under the arm, front buckles that don't ruin your T-Shirt and a stash pocket at the back that keeps your stuff safe. I ordered my usual size, M/L, the bag arrived, I tried it on and it seemed to fit. Then I took it for a long run, having cut the label as you do. And then the problem started - even though I pulled the front straps maximally tight, the flasks bounce a lot, there is too much space between my body and the straps and after a few miles this gets really uncomfortable. It seems the bag is simply too big for me. I can't exchange it because I've cut the labels. The previous model is very differently sized. And the size guide on the website has no specific recommendations for vests. I recommend you try your pack on with full front flasks before buying and jump around a bit - it really comes up large.
