I put together a M50 hammock toe try out. At the time I weighed in just under 220 lbs. It held as I entered and laid in the hammock for about 10 minutes, but when exiting the M50 fabric suffered a catastrophic failure about an inch below the gather.
Currently I'm awaiting a shipment of 1.1 to put together a new (not quite as light) light weight hammock until I shed 20+ lbs. to try out the M50 again.
