How does the complete system work?
The Complete System gives you the Special Forces 1 Bag for use in above
freezing temperatures and the Special Forces 2 Bag for use in
temperatures right down to -10°C. Then, when you’re in extreme
conditions, you place the Special Forces 2 Bag inside the Special Forces
1 Bag and join them together with the extra zip baffle, so you’re
protected in conditions right down to -20°C. Ingenious!

When joined in this way, you retain the convenience of closing and opening
with one central, quick release zip. Both bags have a reinforced foot
area and come with a stuff sack to keep everything together.
