ALL of the following costume elements are required in order to be eligible for 501st Legion membership:

Approx 1.5" (38.1mm) tall mandarin collar with a chevron shaped, left-over-right velcro closure.
On the left forearm there is an empty commpad pocket approx 5" (127mm) wide by 5.75" (146.05mm) tall with no flap and a 2.25" (57.15mm) window in it.
On the left bicep, there is a code cylinder pocket with no flap, and vertical stitching dividing it into pen sleeves.
The bottom front corner of the pocket is cut off at a bevel on the side pointing in view direction
with the broader upside forming the border of the pen sleeves.
The right bicep has a cargo pocket about 6" (152mm) wide and 5.75" (146mm). The pocket has a 2"(50.8mm) flap.
2 large chest pockets and 2 large front pockets below the belt without any zipper or flaps
2 leg pockets with flaps similar in proportion as the one on the right arm sleeve. Size may differ.
(Usually the width of the front pockets equals the width of the leg pockets)
Armor
White chest and back TK style armor, with large flat surface on the chest plate for the chest box.
Snow Trooper style shoulder bells, rotated 90 Degrees, so the ridges of the shoulder bell go along the top, as worn by the Snow Commander.
Circuit Board detail plate on rear of back armour, Black, White and Gold in colour. Grey angled greeblie in centre of the circuit board plate. See illustration below.
Stormtrooper Style ribbed shoulder bridges connecting the front and back armour plates, in White.
Gray webbing 'Ejection Harness' extending from the below front armor to the back armor under the crotch. Two loops wrap around each leg at the knees and are attached to the rest of the webbing at the crotch. This is the same set up as used on the X-Wing pilots.
Rear Armor detail:
Chest Box
Roughly rectangular Chest box attached to front armor plate with the following details:
Size of Chest Box is approx H7" x W7.25" x D2.5"
The top of the Chest box is angled at approx 45 Degrees at the front, sides and rear forming an apex.
Small angled extension on top of Chest box approx H0.75" x W2.00"
The lower half of the Chest box is slightly shallower than the upper half.
There are two cylindrical 'donut' extensions on each side of the box, one above the other, approx 2.35" (6 cm) in diameter.
The upper donut is slightly wider than the lower one and has a hole for the hose that runs from helmet to Chest box.
Custom circuit detail and greeblies on front of Chest box - refer to illustration below
Chest Box detail:
Hose
Grey ribbed hose running from rear helmet canisters, over the shoulders and to the upper donut extensions on the Chest box.
Hose is approx 1" in diameter but the actual size used is unknown at present.
Gloves
Gray or White leather gloves with a 4-6 inch cuff. The brand name WELDAS SOFTOUCH
Tig/Mig gloves appear to be the closest to the screen used gloves.
White Damascus D650 Gauntlets or White/Grey Fencing gloves are a perfectly acceptable alternative.
The left glove cuff has a small commpad on it, approx 1.5" x 1.5" with the outer section slightly curved, and the inner section straight. The Commpad has a circular centre section about 3/4" high, and topped with a small silver disk, slightly smaller than the centre section in diameter.
Boots
White or light Gray “moon” boots. These are very hard to find without some kind of decoration on them, but they are out there.
Snowtrooper style Canadian Muk Luks with ALL lace loops and 'D' rings removed.
Screen used boots
