I got some questions about my backpack. (as seen on my pictures)
I use this one: http://uktactical.com/acatalog/3_Day_Pack.html
It is better proof against sharp objects than normal “plastic” ones.( Like ur tuner and TRX )
There are a lot of possibilities to connect extra bags, and to strap a coat/ plastic sheet on. The price is good and shipping without any problem.
My son used a similar bigger one in military activities in a DX country outside Europe. It is better than the one supplied by the boss.
However, these packs are not watertight, so an elastic plastic cover is handy.
I hope I can help some activators with this info.
