What the legionaries on campaign slept on?

[Tita Iuventia Martia]

Radka,
In some places, people bring a canvas or linen bag the size of a cot mattress, and stuff it with straw or grass and leaves. It rolls up to be pretty compact, and when you leave, you just dump the straw out, and go on your way. The ones I've seen open down one long side, not at the ends, to make it easier to stuff straw in.

Did the Romans use them? Don't know. Not sure if anybody has any info on it, but if anyone does, could you please post it for us? Regardless of provenance, it would be better to have one of these rolled up on your furca than a foam pad, don't you think?

Salve Demetrius,
Thank you for your idea, It seems to be also a cool and handy tip :-) this linen bag would going to be quite wet, if the day will be a bit rainy ;-) ) But, I also have to say, that sleeping on this stuffed bag have to be really comfortable :-) )

Thank you for your post and best regards from Prague :-) )
