The Packa is available in six sizes: Xsmall, Small, Medium, Large, MediumX, and LargeX. Sizing for the Packa really only depends on your height and pack size. The Packa is made very large in the jacket part to aid in air circulation. Rarely do you need to upsize due to weight. Packa sizes do not match with other garment sizes.
XSMALL: For people under 5'2. The XSMALL size also has a smaller packcover than all other Packas. Fits backpacks up to about 3000ci or 48 liters.
SMALL: For people between 5'2 and 5'8. The small, medium, and large all have the same packcover size. Fits backpacks up to about 4600 ci or 75 liters.
MEDIUM: for 5'8 to 6'0. The small, medium, and large all have the same packcover size. Fits backpacks up to about 4600 ci or 75 liters.
LARGE: For above 6'0. The small, medium, and large all have the same packcover size. Fits backpacks up to about 4600 ci or 75 liters.
Backpacks with a volume of 4600 ci or 75 liters work best with the small, medium, or large Packa. Above 4600ci or 75 liters require the "x" size.
The packcover dimensions are roughly about 10 inches deep by 12 inches wide by 29 inches tall. The packcover also has 3 inch pleats on both sides at both the top and bottom increasing the volume beyond simply 10 x 12 x 29.
MEDIUMX and LARGEX sizes have the same jacket size as the regular Medium and Large Packa, but have larger packcovers– up to about 5500 ci or 90 liters. Size Xsmall and small is not available with the “X” size packcover. The packcover dimensions for the “X” size Packas are about 11 inches deep by 12 inches wide by 32 inches tall. The “X” size packcovers also have the 3 inch pleats that increase volume.
NOTE: These sizes are flexible and if you are on the border of a size, you can adjust without a problem.
