The most desireable part of the PCU is naturally going to be the one you'll use the most, and the Level 5 pants are just about the most versatile part of the whole system.
ECWCS/PCU
The protective combat uniform or PCU is a prominent, versatile, and fantastic bang-for-buck US surplus goldmine of incredibly useful clothing. You can read more about the rest of the system in an article here, and see an excellent use guide here.
Sizing
Note: many of the pants we have in stock for now are "Extra large long". Our Model is 6'0" with a 34" waist and was still able to use these with a reasonable fit. see photos for reference.
The sizing follows the US army's standardized sizing system, which will stay the same across all other uniform pieces you purchase. If you know your US Letter Pant size, that will typically work for the main size, but just in case, here's the sizing in waist circumference:
'Small' — 27"-31"
'Medium' — 31"-35"
'Large' — 35"-39"
'X-Large'— 39"-43"
'2X-Large'— 43"-47"
For the length portion, this is mostly determined by your height.
'Short' — 5'5" - 5'8" (typically 29-30" inseam)
'Regular' — 5'8" - 5'11" (typically 32" inseam)
'Long' — 5'11" - 6'2" (typically 34" inseam)
'Extra Long' — 6'3" - 6'6"
A vast majority of people will choose the "regular" length, which changes slightly across garments to keep desired proportions. Taller folks with shorter legs may wish to stick with "regular" length as well.
Pants are in unissued condition, in factory original packaging.
