The medium pack is often carried using the shoulder straps without the pack frame, as shown in figure 2-15. To attach the straps to the pack, follow the same procedure as used in attaching the straps to the frame.

Figure 2-16.-Ground mat attached to medium pack.

l Insert the webbing at the top of the strap through the metal loop on the top of the pack and pull it tight. (See fig. 2-15, view A.)

l Insert the looped end of the strap through the D ring at the bottom of the pack through the strap loop and pull it tight. (See fig. 2-15, view B.)

Be sure the strap with the quick release is over your left shoulder.

CAUTION:

When the medium pack is to be worn in extreme cold climates, it must be worn on the frame. See figure 2-18 for the manner of attachment. Using the frame prevents accumulation of perspiration in the area where the pack makes contact with the back of the individual, which could cause rapid cooling of the individual.

Attaching the Ground Mat

The ground mat can be carried inside the pack or attached to the outside. Figure 2-16 shows one way of carrying it by attaching it to the bottom of the medium pack with two cargo straps pulled through the loops on the bottom of the pack.
