Sizing notes:
-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.
For users over 220lbs or 6'4", please contact us for custom sizing. Custom sizing is $10 in most cases.

Please check the homepage for lead times before ordering to see the date when your bivy will be sewn and shipped.
Cuben bivys ordered after December 23rd will have a 1.0oz DCF floor instead of 0.8oz DCF. This adds 0.45oz to the finished weights in the table above. This will be the case until we get more 0.8oz DCF on the way.
