First is the issued Day Sack.
Second is a rare piece, the Infantry 90l Bergan but heavily modified with 3 pouches to the front and also a 4th pouch under the lid. The Bergan itself has a IR patch to the front and has been lightly sprayed a Matt grey. I asked the chap who I bought it off the history, he just said it came from somebody Special!!
90l infantry Bergan looks like it has been modified to mirror possibly the 'Airfield Support Bergan' which is issued?
