In the services I had
58 Large Pack - a poor excuse for a bag
GS Bergen - Too small as a Bergen but not a bad patrol sack without the frame
SAS Para Bergen - I used one of these on selection (which I failed) but quite liked it.
Ski March Bergen - not too bad on the shorter fame
PLCE Trials Bergen - Not too good, a lot of issues compared to the Berghaus
Berghaus Crusader - Spot on.
Berghaus Roc - Best available in its day*
Karrimoor 80-100 - Not bad but needed spraying.
Artic patrol sack - dreadful
Unit made 35 litre Patrol pack copy of a Berghaus Munroe - Made by the equipment repair guy in 45 commando from an old Tan seamans kit bag, awesome kit - sold it and regretted it.
Karrimoor SF DPM 40 litre patrol sack - Sold it and regretted it, bombproof
PLCE trials patrol sack zip opening top, plain green - gave it to the cadets
German Airborne Rucksack - Not bad, improvement on 58 large pack.
SADF rucksack - ok but not particularly rugged, with poor zips.
ALICE MEDIUM WOODLAND - Very good I liked it and sold it.
PLCE Green Bergen - Good kit
PLCE Other Arms Bergen - Excellent patrol sack*
PLCE DPM Bergen - Short back perfect for me.*
Bowman radio sack DPM - I love this*
Proforce Highlander 35 Litre patrol sack tan - Much better than you might think*
ProForce Highlander 80 litre DPM Forces Bergen - this belongs to my son who had it in the cadets, he is no in the Army but had nothing but praise for this Bergen. (now lives in the loft)
ProForce HMTC/MTP Patrol sack 40 litre with MOLLE bits over it - My son swears by this*.
DPM NI patrol sack - I have one so does my son, bomb proof, fairly comfortable and carries a good load.*
Green Webtex copy of above - OK but unconvincing
Black Field Pack 35 litre, issued- less use than dogs muck on your boot and less durable than a plastic carrier bag from Tesco.
US Army National Guard laptop rucksack - very posh, black cordura and embossed leather*
US Army National Guard garrison day sack - OK*
US Army National Guard Insulated Lunch bag - How posh is that?*
Swiss huge Bergen - Rubberised canvas, leather bottom, two external pouches, internal frame. Sort of a Swiss PAPA Bergen. One of the best constructed and thought out things I ever possessed, a bit like my Rolex watch
On the way a British DPM Medium ALICE pack ex Royal Bermuda Regiment - Odd purchase since I am now a civvi
* are the ones I still have
