Zpacks Twin Bathtub Groundsheet lightly used and in excellent condition.  This size is no longer offered.

My measurements show:

35″ (97 cm) wide at the ends, 50″ (127 cm) wide at the center, 88″ (213 cm) long with 3 inch bathtub. Zpacks advertised 5″ inch bathtub but I don’t see it.  Maybe in the middle (tying up with loops) but not on the ends.

 

Prices includes shipping in CONUS and payment by Paypal or Venmo.
