German Patrol Rucksack
The standard rucksack for Bundeswehr troops at East Wind is the 65 liter patrol rucksack. You will find these either as original surplus or as Miltec reproductions. The original military units are of superior manufacture and are recommended however the Miltec repros are acceptable.
You will find that your patrol ruck sack carries a great deal better with the original German folding ground mat installed in the pouch found in the main body of the pack.
The 35 liter "Jager" ruck is a nice addition as well but does not meet this requirement.
