About Your Helmet
A helmet can provide important protection if fitted
and worn correctly. Important safety information:
A helmet must be correctly worn and maintained
to provide protection. Carefully read and follow
these instructions. Incorrect use or maintenance of
your helmet could lead to serious injury or death.

4
Ride Safely
No helmet can protect the wearer against all
possible impacts. A severe impact, sharp object,
improper use, or incorrect adjustment could cause
conditions beyond the protection of the helmet.
Check the adjustment before every ride
To be effective, a helmet must fit and be worn cor-
rectly. The helmet is designed to be retained by a
strap under the lower jaw. To check for correct fit,
place helmet on head and make any adjustments
indicated. Securely fasten retention system. Grasp
the helmet and try to rotate it to the front and rear.
A correctly fitted helmet should be comfortable
and should not move forward to obscure vision
or rearward to expose the forehead. If you cannot
correctly adjust your helmet, consult your dealer.
Avoid high heat
Do not expose your helmet to heat, such as inside
a car on a sunny day. Excessive heat can damage
the liner or shell, or make them separate.

5
Avoid chemicals
The helmet may be damaged and rendered ineffec-
tive by petroleum and petroleum products, cleaning
agents, paints, adhesives and the like, without the
damage being visible to the user.
Replace an old helmet or helmet with damage
The helmet is designed to absorb shock by partial
destruction of the shell and liner. This damage may
not be visible. Therefore, if subjected to a severe
blow, the helmet should be destroyed and replaced
even if it appears undamaged. The helmet has
a limited lifespan in use and should be replaced
when it shows obvious signs of wear. Helmet parts
lose strength over time, so even if the helmet has
not been impacted or damaged, replace it after
three years.
Helmets vary in both design and protection.
This helmet is designed for use in recreational
bicycle riding; it does not offer the same
protection as a helmet designed for use in
rock climbing, roller-skating, or skiing. Make
sure your helmet is designed and intended
for your type of bicycle riding. If you choose
to do stunts or tricks, ride off-road, or ride
at high speeds, you should choose a helmet
with more protection.
WARNING

6
Anything between your head and the helmet
can reduce the protection. A cap, scarf,
or even some high-volume hairstyles might
allow the helmet to move during an impact.
Barrettes, headphones, or anything else
under your helmet can injure you if the helmet
is impacted.
Do not modify the helmet. No attachments
should be made to the helmet except those
recommended by the helmet manufacturer.
This includes stickers or adhesive labels.
Avoid choking. This helmet should not be
used by children while climbing or doing
other activities where there is a risk of
hanging or strangulation if the child gets
trapped whilst wearing the helmet.
Keep your helmet clean. Wash it with a
solution of mild soap and water. The t pads
are machine washable in cold temperature,
gentle cycle. Do not put t pad sets in the
dryer. You can also buy new t pads from
your dealer.
Ventilation holes may allow penetration.
Sticks, stones, or insects can pass through
the holes to the interior of the helmet.

Replacement Policy
If your helmet is impacted within the first
year of ownership, Bontrager will replace
it at no charge. Ship the helmet, postage
prepaid, to Bontrager customer service
with a copy of your receipt and a description
of the accident. We will send you a new
helmet upon receipt of your crashed helmet.
Adjusting the Helmet
Bontrager offers two childrens’ helmet models
to fit different head sizes: Little Dipper and
Big Dipper. To check the shell size of your helmet,
put it on the child’s head in the correct position
(see Figure 1 and Figure 2), but do not fasten
the buckle. A good fit is snug, but not tight.
Note: All directions (left, right, top, bottom)
are in reference to the helmet as worn
on the head.

To Adjust the Left Temple Strap
1. Place the helmet on the child’s head.
2. Unlock the strap adjustor (Figure 3).
3. Slide the strap adjustor on the left temple
strap (Figure 4) until the strap adjustor sits
just beneath the left earlobe.
4. Hold the strap adjustor position on the temple
strap while you pull the nape strap (Figure 4)
through the nape adjustor. The left buckle
should almost touch the strap adjustor.
5. Lock the strap adjustor.

Strap (2), and Left Nape Strap (3)

To Adjust the Left Nape Strap
1. With the helmet off, pull the left nape strap
(Figure 4) through the back of the helmet
(Figure 5) to adjust the position of the
left strap adjustor.
2. Put the helmet on. With the helmet correctly
positioned on the head, the left strap adjustor
should be just below the earlobe (Figure 6).
Both the temple strap and the nape strap
should be taut.
3. If necessary, re-adjust the left temple strap
(see previous section).

To Adjust the Right Nape Strap
and Right Temple Strap
1. With the helmet off, open the right
strap adjustor.
2. Slide the right strap adjustor on the nape strap
until the right nape strap is the same length
as the left nape strap.
3. Pull the right temple strap through the right
strap adjustor until it is the same length
as the left temple strap (Figure 7).
4. Lock the strap adjustor.
5. Put the helmet on and check the helmet
adjustment.
+Both strap adjustors should be just below
the ear lobes.
+Both the temple straps and nape straps
should be taut.
6. If necessary, re-adjust.

To Adjust the Chinstrap
The helmet is designed to be retained by a strap
under the lower jaw. The two straps hanging from
the right strap adjustor that go under the lower jaw
are collectively called the chinstrap (Figure 8). Make
sure the chinstrap is correctly threaded through
the right buckle (Figure 9).
1. Adjust the length of the chinstrap by sliding
it through the buckle.
2. nsert the right-hand buckle into the
left-hand buckle (Figure 10).
3. Make sure the buckle is correctly fastened:
+Listen for a click as the buckle engages.
+Attempt to pull the buckle apart with
the chinstrap; it should not come apart.

of Chinstrap Figure 9. Path of Chinstrap Through

Figure 10. Chinstrap Buckle Unfastened
and Buckle Fastened
The chinstrap should be located as shown
in Figure 8 and should fit snugly against
the bottom of your chin. If not, re-adjust.
4. To keep the chinstrap from flapping,
tuck it through the rubber O-ring (Figure 9).

Quick SetTM fit system
This system works to add comfort and security
to the fit of the helmet. It is self-adjusting, but to
work best must be placed on the head correctly.
Place the Quick Set strap (Figure 11) just below
the occipital lobe, the bony protrusion at the base
of the skull (Figure 12).

Set strap Figure 12. Occipital lobe of head

14
To Adjust the Fit System
1. Put the helmet on the child’s head, but do not
connect the straps.
2. Position the fit system so that it is below the
occipital lobe, the bony protrusion at the base
of the skull.
3. Buckle the chinstrap.
4. Test the adjustments (see next page).

15
To Remove the Helmet
While pulling lightly on the chinstrap, press on both
of the recessed tabs of the buckle (Figure 13).
Figure 13. Opening the Buckle
To Test the Adjustments
Perform each of these two tests:
+Shake your head side-to-side. The helmet should
not move on your head.
+Attempt to push the helmet forward and
backward on your head. If the helmet moves
back, tighten the temple straps. If the helmet
moves forward, tighten the nape straps.
If the helmet cannot be adjusted correctly, you may
need a smaller shell size; consult your dealer.

16
Cutting Excess Chinstrap
If you choose to cut the chinstrap, leave at least
1 inch (25mm) above the buckle. A chinstrap
that is too short may lead to the helmet losing
its adjustment and protection. After cutting,
melt the end of the chinstrap to prevent fraying.
Be careful with high heat near the helmet. The
strap is flammable. Until it cools, avoid contact
with the melted nylon because it can burn.
