| Neck Seal Drysuit Sizing Table |
|
| When trying on a neck ZipSeal that is not on
a drysuit, be sure to trim it at least one ring size too
small. Then try on the neck ZipSeal again after it is installed
in the drysuit. The weight of the drysuit can pull on the
neck seal making it feel looser. Trim additional rings if
necessary. |

Latex neck and wrist seals are trimmed
to fit to provide a comfortable water-tight seal. Latex seals
are tapered and have a series of trim lines (small raised lines
running around the outside surface of the seal.) The trim lines
start at the seal opening and each line gets progressively
bigger. These lines can be used as a guide when trimming the
seals to keep the line even. A good pair of scissors is needed
to make smooth cuts. Use the Seal Sizing Table above to determine
the best starting point for you.
Start by measuring the circumference of your neck and wrists
and compare these measurements to the Seal Sizing Table. This
will establish a starting point. If your wrists are different
sizes you can trim each seal to match each wrist.
Try on the seal (it isn’t necessary
to put the entire drysuit on to try the neck seal.) For the
neck seal, position the seal as low on your neck as possible.
It should be snug, but not tight. If you are new to drysuit
diving, a snug neck seal may feel a bit uncomfortable out
of the water. Once in the water, a properly timed neck seal
is comfortable.
Wrist seals should be worn just above the wrist bone*. They
should be snug but not tight and should not restrict blood
flow to the hands. If you experience tingling in your hands,
trim seals further.
If this is the first time you have trimmed seals and you are
concerned about over trimming the seals, start by moving down
one size than shown on the Seal Sizing Table. If the table
recommends trimming at line 5, start by trimming at line 6
and check the fit. If the seal is overly snug you may want
to make an additional trim between lines 5 and 6. Trim in small
step.
*A percentage of divers have a tendon that causes an indentation
when the wrist is curved. This will cause a leakage when the
wrist is flexed during the dive. In this case the diver should
wear the seal higher on the wrist (up the arm) past the tendons.
Special Note on
Latex Ankle Seals: There is only one trim
line on latex ankle seals. In the event you receive a drysuit
and the ankle seal has not been trimmed, trim the ankle seal
on the trim line.
ANKLE SEALS - Putting the Drysuit Seals
On
Some DUI drysuit models are equipped with latex ankle seals:
- If the drysuit has a protective ankle cuff, undo
the velcro and pull back the protective cuff completely exposing
the ankle seal
- Put the foot all the way through the leg but not into
the ankle seal
- With both hands, insert your fingers into the seal from
the outside of the suit
- Stretch the seal as wide as possible while pulling it
over your foot
- The ankle seal should lay flat against your skin right
above the ankle bone. Be sure there are no wrinkles or folds
or any items under the seal, i.e. divewear
ANKLE SEALS - Taking the Drysuit
Seals Off
- If the drysuit has a protective
ankle cuff, undo the velcro and pull back the protective
cuff completely exposing the ankle seal
- From the outside of the suit, reach through the bottom
of the ankle seal with your fingers from both hands
- With your fingers inside the seal and thumbs on the outside,
reach through and grab the fabric of the suit
- Carefully pull the suit over the foot
