Seriousely - if you need a hip pad then you are not wearing your webbing right. The belt needs to be around your waist - don't carry too much crap and overload it - and lower the belt when packing a bergan. I was inf and carried all sorts from shovels & picks, GS bergans, spare rounds for Charlie G, spare rounds for moratrs, spare link for the GPMG, GS carriers with radios (58 pattern) - to PLCE with most of the above. I never had a problem and never got webbing burns from the belt.
Unfortunatly SASS don't stock that anymore , I rang them the other day and they said they can't get the padding materials in, something to do with all the clothing contracts going out to China.... they haven't taken if off their website yet though.
