Hi Kevin,
I recently bought the 60+10 womens version for my daughter for her Duke of Edinburgh expedition. She found the bioflex system to be very comfortable. It also has an adjustment for the length of the back. It did creak a little when empty and new, but not when fully loaded. However, she only wore it for 2 days, so I can't say it will stay silent forever. It is a very well made, sturdy rucksack. I bought it from Gaynor Sports, who had the best price.
I hope this is helpful.

I'm looking to get a multi day pack and having done a bit of research on the net am very tempted by the Berghaus C7 packs. The only reservation I have is a number of reviews have reported an extremely annoying squeak which develops after a day or two of use.

The most recent review I've found was from over a year ago so I was wondering if anyone had a more up to date opinion on this particular pack?

- If it does squeak can this problem be easily fixed? Apparently Berghaus advised one complainant to put a bit of vaseline between the moving parts?
- Does it only squeak when massive loads are placed upon it?
- Are there other equally as comfortable packs out there which don't make such a racket?

Any info / advice much appreciated.

Cheers

Kevin
