INTRODUCTION
The Bianchi UM21 Backpack System features the latest advancements in state of the art technology. It combines materials, construction, and fit to provide a backpack for the 21st century. This
Universal Military Backpack System gives the modern day battlefield warrior the ability to carry
required loads over long distances with greater ease and comfort.
Termed the Special Operations Forces Personal Equipment Advanced Requirements (SPEAR),
and Body Armor Load Carriage System (BALCS) by the US Army, consists of three subsystems: 1)
Body Armor Subsystem, 2) Equipment Load Carrying Subsystem (ELCS), and 3) the Backpack
Subsystem. Each Subsystem can be worn independently, as a total system, or in multiple configurations
to meet mission requirements. This Use and Care Manual describes the Backpack Subsystem.

SPEAR SUBSYSTEM
CONFIGURATION
The three main components:
Backpack, Patrol Pack, and Butt Pack,
have been designed to work together as
a system, or can be used independently.
BUTT PACK
The Butt Pack is issued with a compression stuff
sack and offers 3 modes of carry:
1. Carry Handle
2. Universal Attachment System
3. Waistbelt
To remove for independent use, unsnap the two
Universal Attachment System straps and use the
waistbelt. To reattach the Butt Pack to the Backpack,
stow the waistbelt in the pocket provided and
reattach it to the Backpack with the Universal
Attachment System.
SIZING:
MEASURING TO FIT
THE BACKPACK
The measurement to fit the Backpack to the user
is a two-person operation. The measurement is
critical to ensure a proper fit. A SPEAR automatic
sizing device (FIG. 1) will be provided to assist
in measuring for a proper fit. The SPEAR automatic sizing devices were initially fielded to the
unit with Backpacks. Once you have obtained a
SPEAR automatic sizing device, proceed as follows: Place the waist belt on your hips at the top
of the hipbone. Tilt your head slightly forward.
This exposes the top of the seventh vertebra. This
is the bone where the shoulders meet the neck.
Have the person assisting you with the fitting of
the pack unsnap the vertical adjustment piece and
place the hole, located at the top of this device,
over this bone. Follow the scale down to the point
on the vertical adjustment piece to where it points
to a number. This number corresponds to a slot
location on the pack. That is the slot location
where the figure eight slider should be placed.
PATROL PACK
The Patrol Pack is issued with its own storage sack
and two compression stuff sacks. When utilizing the
entire SPEAR System, the Patrol Pack can be stowed
behind the compression flap on the Backpack or
attached to compression flap on the Backpack using
the buckle system common to each pack.
BACKPACK
The Backpack is issued with two compression stuff
sacks located in the sleeping bag compartment. The
Use and Care Manual can be found in the rain flap.
Key features of this pack include:
1. Removable Side Pockets
2. Universal Attachment System
3. Quick Release Buckles
FIG. 1 Automatic Sizing Device (available for purchase separately - call
for information).

ADJUSTING THE
BACKPACK SHOULDER
HARNESS
There are five separate harness
adjustment slots. The pack is
shipped from the factory with the
shoulder harness attached to the
middle slot, which has been found
to be the correct setting for the
greatest number of users. If your
back measurement (see page 8)
determines that the shoulder harness
needs to be adjusted, follow the
instructions below:
1. To gain access to the shoulder
harness assembly, insert your hand
into the pack behind the radio pouch
(FIG. 2). You will be able to see
your hand behind the five separate
slots. To change the position place
your hand inside the pack and locate
the five slots and find the figure
eight slider. Turn the slider perpindicular to the slot opening (FIG.
3) and push one side of the slider
through the back. Then pull the slider completely through the slot. This
releases the harness.

2. To re-position the harness to a different slot, turn the slider level to the
slot, insert one side of the slider into
the slot, (FIG. 4-5). Push the slider
and then pull it completely through
until it is set in position and lies flat
against the frame sheet (plastic
back).

INITIAL ADJUSTMENT
AND FITTING OF THE
BACKPACK
Note:
During the initial
set-up and adjustment
procedures the Backpack
should be empty.
Putting the Pack On
1. Loosen all suspension straps:
Shoulder Stabilizer Straps,
Lower Shoulder Adjustment
Straps, Waistbelt Stabilizer
Straps, and Waistbelt. Unsnap
the Sternum Strap
Fig. 8
Fig. 9
Fig. 10
Fig. 11
Fig. 12
Fig. 13
2. Using your legs to lift the
weight of the pack onto your
body, slip one arm and
then the other through the
shoulder harness. Tighten the
Lower Shoulder Adjustment
Straps first, until snug (FIG. 8).
3. Shrug your shoulders skyward
(FIG. 9) (this will raise the
pack) and fasten your waistbelt
(FIG. 10)-- making sure that the
top edge of the waistbelt is 1”
above the top of your hipbones (FIG. 11).
10
4.Tighten the waistbelt one side at
a time. (FIG. 12-13), relax your
shoulders and retighten the
Lower Shoulder Adjustment
Straps.
5. Re-tighten the Shoulder
Stabilizer Straps by pulling
down on the straps(FIG. 14-15).
6. Tighten the Waistbelt Stabilizer
Straps by pulling them forward
(FIG. 16).

FINE TUNING THE
SHOULDER HARNESS
1. LOAD CONTROL PANEL
The Load Control Panel (Fig. 20)
is located on top of the shoulder
harness. Because it is attached to
the harness pad with hook and
loop it can be moved from one
position to another (FIG. 20).
Choose the best position for you.
The Load Control Panel is shipped
with placement in the middle
(FIG. 21). If you move the Load
Control Panel to the inside of the
pad it will cause the shoulder harness to be farther away from the
neck FIG. 22). If you move the
Load Control Panel to the outside
of the pad it will cause the harness
to be closer to the neck (FIG. 23).
2. LOAD STABILITY
The angle of the shoulder stabilizer strap is controlled by adjusting
the metal slider located on top of
the Load Control Panel. The metal
slider should be adjusted so that it
is even with your collarbone.
(FIG. 24) This adjustment is
important for load stability and
weight transfer adjustments.

3. STERNUM STRAP
The elastic Sternum Strap is fully
adjustable up and down the shoulder harness. It should be located
approximately 2 inches below the
top of the sternum. To re-position
it, unsnap the strap and re-locate
along the shoulder harness for best
comfort. (FIG. 25).
12
WAISTBELT CANT
ADJUSTMENT
(coin or screwdriver required)
With a full pack on, the top edge of the waistbelt
should ride about 1” above the top of the hipbones
(Refer to FIG. 11 on page 10). Note that the pads on
the waistbelt are molded to fit the hips and the entire
waistbelt is angled to match the natural angle of the
hips. The angle of the waistbelt can be adjusted to
better match the slope of each user’s hips. This easy
one-time adjustment makes a big difference in comfort when carrying heavy loads for long periods.
To adjust the waistbelt angle, start by unsnapping the
waistbelt pad. Reach underneath the lower back pad;
slide your fingers inside, find the snap and pull.
Loosen the Waistbelt Stabilizer Strap and slide the
pad away from the lower back pad (FIG. 26).
Moving the waistbelt pad reveals two brass screws
and three settings on each side of the waistbelt
(FIG. 27).
FIG. 26
FIG. 27
To change the setting, unscrew the brass screws and
move them to one of the three settings (FIG. 28).
You will note that the backpack is shipped with the
waist belt set in the top hole. Moving to the middle
or bottom hole will increase the amount of angle
(FIG. 29). When the adjustment is complete, slide
the waistbelt pad back over the lower back pad, fasten the snap, and re-thread the Waistbelt Stabilizer
Strap.
For users with few body contours, use the top setting
for minimum angle. For those with more body contours choose the middle or bottom setting for maximum angle. The setting is correct when the waistbelt
lies evenly on the hips (FIG. 30).
FIG. 28
FIG. 29
If gaps exist between your body and the waistbelt -either on the top or the bottom-- disassemble and try
another setting until you find the fit that best matches your specific body contour.
FIG. 30
13
CHECKING FOR CORRECT FIT
To evaluate the fit and operate the
load transfer controls, you should have
the Backpack loaded with a minimum
of 25 pounds.
1. Loosen all suspension straps. Use your legs
to lift the pack onto your body. Tighten the
Lower Shoulder Adjustment Straps first.
LOAD TRANSFER CONTROLS
By utilizing your pack’s suspension adjustments,
you can shift the weight entirely onto your hips, or
entirely onto your shoulders -- or distribute it
between the two. Similar to electric seats in a car,
the pack allows you to change the weight transfer
surfaces as you proceed on the march. Experiment
on the march to find the optimum adjustment for
various terrains and conditions.
2. Shrug your shoulders skyward and attach
your waistbelt -- making sure the top edge of
the waistbelt is one inch above the top of
your hips.
To Shift Weight From Hips to Shoulders:
3. Now tighten your waistbelt, re-snug all straps
and check the fit.
3. Lightly re-tighten the Shoulder Stabilizer Straps
to stabilize the top of the pack. You may want
to loosen the waistbelt for a full weight transfer
to the shoulders.
Check off these points to ensure your
pack system fits properly.
1. Loosen the Shoulder Stabilizer Straps.
2. Tighten the Lower Shoulder Adjustment Straps.
To Shift Weight From Shoulders to Hips:
1. Correct Shoulder Harness Slot?
With the top edge of the waistbelt 1”
above the top of your hip bones, the
shoulder harness should wrap over the
shoulder in back. Is the harness in the
right slot?
2. Position of the Metal Slider?
Check that the metal slider is even with
the collarbone.
3. Did You Fine Tune the Shoulder
Harness?
Does the shoulder harness wrap smoothly
across the chest, centered over the shoulder? Check the position of the Load
Control Panel to move the harness either
closer to the neck or farther out.
4. Correct Adjust-A-Cant Waistbelt
Setting?
The waistbelt should lie evenly against
your hip angle -- there will be no gaps on
the top or bottom edge of the waistbelt.
5. Sternum Strap in Best Spot?
The sternum strap should cross the upper
chest in the most comfortable area.
14
1. Loosen the Shoulder Stabilizer Straps and
Shoulder Adjustment Straps until you feel
the weight of the load shift downward onto
your hips.
2. Tighten the Shoulder Stabilizer Straps until
there is about a finger’s width of space (a gap)
between the top of your shoulders and the
shoulder harness.
3. You may want to tighten the waistbelt due to
the weight transfer.
