Ok I've been told by my training team that you pack your kit in the main part of the bergan into a dry bag, then close it and put your sleeping bag in its bivi bag on top. But Iâve read a couple of people on here saying they put the sleeping bag into the dry sack along with their kit, which method is correct/best? Also I'm currently using the forces 33 day sack but because it has a semi-rigid backing to it its a bit annoying trying to stuff under the bergan lid (also I think that the back on it keeps knocking my Kevlar down my face when prone). How compressible is the NI patrol pack as I just found one for Â£30 and heard itâs meant to be pretty good. Thanks.
