  -If you use a 25" wide pad, go with a wide bivy. In general, users under 180lbs fit well in a regular girth, and 180-220lbs in a wide. Over 220lbs please contact us for custom sizing.

  -Custom sizing is almost always free, so shoot us an email if you need something bigger or smaller than the standard sizes.
