OMM ORIGINAL MOUNTAIN MARATHON Men's Ultra Running Backpack

The best running pack I’ve owned – and I’ve had quite a few. A bit of a bag geek, this is perfect as a run-commute bag and a day-pack. It is minimalist – one main compartment, no laptop sleeve or section for wet clothes – but this hasn’t been a problem. Wet clothes go in a tote and laptop doesn’t need an extra compartment.Most importantly it wins by being very light and easy to secure so it is comfortable to run with. The belt pockets are great – one zipped one elasticated to stash stuff in while you run – and there’s a water bottle holder cunningly built in in that is useful.If you are using it for its intended use – ultramarathons – it has a bit for mounting poles, which I understand would be useful.

I got the 20L one for run-commuting 5k to work. Been using it a couple of months. It's basic but very lightweight and I haven't managed to destroy it yet. It doesn't come with compression bungees, so you might want to source these for it. I can just about fit everything I need in it - shoes (but I have small feet), clothes, towel, toiletries, lunch. I would recommend it.However, If you are a petite female like me (44kg, 5ft2) read on...... I asked around if it would fit me okay as I have was worried it would not strap down small enough for me and I obviously didn't want it jiggling around. I was assured it would. However, as usual with everything I ever buy, it is a bit too big - at the smallest it will go and after playing around with the height of the waist strap, it just doesn't fit well on my small frame - the shoulder straps are too long and gape so the pack doesn't fit snuggly against my back and the chest strap doesn't go small enough because it just draws the excessive lengthy/gaping shoulder straps together with no resistance, and I can't find the right height for the chest strap to comfortably accommodate my boobs. Also the shoulder straps are too wide for me and rub against my neck so I end up with two sore red patches. None of this would be an issue with someone that isn't so petite though.

Probably best run commute back pack I've had (so far). Deceptively fits what I need in and also has some handy pockets. There is a divider in the main compartment which can be useful. Perhaps there could be some more padding in the back area. I'm interested in a larger version than the 20lt. Would recommend for those wanting to run commute with small load (shirt, trousers, underwear, light towel etc.).

Great backpack, super light, strong and does't let the rain in.I did add a bungee cord to it so I can tightening when running so stuff doesn't rattle around in the back.

Good quality back pack of which it’s best quality is it’s fit.Two things to note:- there is no pouch for a laptop hence if the bag isn’t full it can swing about which is very uncomfortable- the inside of the upper pocket is wearing away against items in the main pocket. im a little worried they’ll eventually fall through!

I use this for commute running and it does the job nicely. Comfortable and I can get my suit in it. Nicely lightweight.

Very smart lightweight piece of kit
