How does the size of the sleeping bag compatment compare to similar bags?
I would say that the compartment in this bag holds up well in terms of space and quality with most top brand named bags.
The sleeping bag compartment is a little small compared to a larger pack like the 65L. But if you can make it fit.
It's a bit small. I have a +30 sleeping bag that's a bit tight in there; but you can open the top of the sleeping bag compartment into the rest of the bag which is what I did. A smaller stuff sack would fit my bag into the compartment easy.
