Hi all looking into gettinig 1 of these want it to be around 35l-40l any suggestions

i recently got the Vaude triset ultralight 35 ltr, cant fault in any way whatsoever.
You need to have at least a 30 inch waist to use it though, im a 28 and found it a little too loose even on full adjustment, i modified it a little to fit me and its been great.

She & I each got Deuter ones recently - done three 10-day walks now - worked very well.   Just be sure, if you're female, to get a good fit as each make and each user varies considerably.
