I have for sale a lightly used Gossamer Gear Mariposa in a size Small with a size Small hipbelt.  This is a 2013 model and was used by my son on about 4 or 5 overnight backpacking trips before he outgrew it.  It is in absolutely perfect condition with no signs of any wear.  $150 to your door in lower 48 if you use PayPal F&F.  Add 3% for regular PayPal
