I was looking for a ~20 litre pack and struggling to decide, so I bought ALL the Osprey ~20l packs (over £1,000) so I could try them all. They all offered something I liked but you know I couldn't find one that ticked every box for me, this Talon 11 ticked most!Pros- It seems bigger than 11 litres. I was able to put almost as much gear in this as some of their 20 litre packs- It looks narrow and neat on your back, not big and bulky- It's very comfortable- It's not as hot and sweaty as I thought it would be (I wanted a trampoline back)- The hip pockets are big enough to be usable (some other bags are big enough for just a car key, literally!)- Stow on the go walking pole holders work wellCons- The bladder pocket is flawed and needs to be redesigned.

It is very difficult to get an Osprey bladder in there (I'm using the narrower blue one) as the bladder is wider than the space, caused by the load lifter straps being in the way. Yes you can loosen the straps, or even remove them, but this is a faff. Also, the strap that supports the bladder has been sewn onto the soft flexible part of the bag rather than the stiff back support. This means when you have 1-2 kilos of water in there the weight pulls down and distorts the top the bag making it look a right mess.- No integrated rain cover.I've used this bag on two ultra challenges now, both were 100km continuous walks. They stow on the go worked well, I was frequently putting my poles back in the loops and found I could do this without even stopping or slowing down just by leaving the poles fully extended. The hip pockets were accessible and big enough for extra snacks. The bag didn't make my back too sweaty (I was expecting it to), being small and narrow probably helped this. And it was comfortable. I will be modifying the bladder support strap myself. It would be nice to have an integrated rain cover, I know their hiking specific bags have one, but this is not a big deal for me as I have a separate one from another bag, and I can leave it at home if the weather is great.

Bottom Line: Great Day BagI normally use a regular backpack for hiking but it wasn’t good for allowing air to flow so my back was always sweaty. I figured it was time to get a true day bag so I decided to try this Osprey 11 since I already own an Osprey 40 and could use the water bladder from that in the day bag. I’ve taken this a few hikes and a few trail runs and it met the need although running with water swishing isn’t ideal. If you’re looking for a nice day bag, consider this one.Cons:- expensive ($90)- missing the strap magnet for my bladder tubePros:- nicely built- durable- light weight- plenty of pockets- good size for a day bag

You can’t go wrong with an Osprey. Bought this bag for snowboarding. The bag is not bulky and fits whatever I need to bring with me. Side pockets are a big plus for easy reach items. Hydration compatible. The only thing missing, is the tuck able rain cover like i have on my Stratos 34 and Hikelite 18. I purchased the XS rain cover separately which fits perfectly over the bag. All in all great bag, will use it as well for trekking.
