Length: Standard fits users up to 6'1", Long fits users up to 6'4"

Width: Standard is 73" in girth at the shoulders, 64" at the feet. If the user is under 180lbs, use a regular width.

Wide is 78" at the shoulders and 66" at the feet. If the user is 180-220lbs, use a wide. If you use a 25" wide pad, go with a wide regardless of weight.

For users over 220lbs or 6'4", please contact us for custom sizing. Custom sizing is free in nearly all cases.

Each oversize option (long length, wide girth) adds about 0.2oz, so a long/wide would weigh ~0.4oz more
