Gear

Hi there

Is anyone using this bag for fell running at the minute? If so how does it hold up during the day? Does it bob up and down or is it stable on the back?After filling your bladder to its full level, is there much space in the pack for other provisions such as wet gear, food, first aid kit and storm shelter etc?

Is it comfy and what size should i go for, im 5'10" so s/m or m/l??

Thanks in advance for comments.

I guess so They are still very new of course. I suppose you've seen the review on here?

Since the smallest manta is 20L there should surely be more than enough space. Still its ~1kg and a lot of money.

The raptors seem to be the ones coming in smaller sizes - 6/10L maybe enough? There's certainly a non trivial weight/cost penalty involved with the hydration system so you'll need a reason to actively want it.

I read the review here and was encouraged by it but i was hoping to have a runners view on it. in theory, it should do the job although theories have been proved wrong in the past. Mainly im interested in how stable it is when running, and how effective its compression system is. Theres nothing worse than having gear, water and sack bobbing up and down when runnin. 

Im aware of lighter race specific bags from innov8 and omm but i like the look of this and because im a fan of osprey packs. I'd also be looking to use it for daywalking trips too so see the extra space in the 25L version as a plus. 

That is the other thing - talon 22 @ 800g/£60 vs the manta 25 @1.05kg/£85.

Of course if you don't already have a hydration bladder (and need one) then much of that price difference will go away. The weight difference gets smaller when you put a bladder in the talon too of course.

Still its there. But you may have a history of finding bladders not to work so well for you in which case it could well make sense.

(I've had absolutely no probems in my sacks but walking not running so rather less likely to.).

I have a sourse widepac 1.5l and its great but its the mantas system im looking at, when running, bladders tend to get forced down into the bottom of the bladder pouch and on more than one occasion, this has led to other items in the pack blocking the flow of water to the tube. Meaning you have to stop and faff about top rectify the problem.

The mantas system of separating the bladder from the main pack means that cannot happen, instead the pressure from the load in the main compartment is used to increase the pressure of the water flow with the added benefit that the water isnt sloshing around in the bladder as it does in regular bladders when running.

The manta also claims that the compression system on the pack is such that, the load is totally stabilised, eliminating any movement when running.

Its this that has me impressed (in theory). I also live in Ireland and we have no proper gear shops to try the pack on so before i order one online i was hoping there would have been some early users of it that could vouch for ospreys claims.
