So after much consideration, I decided to purchase the Hennessy Scout Zip. Because the Hennessy website has been out of stock, I purchased it from another online retailer.
All the specs I've seen online list the scout as being rated to 200lbs, and I felt comfortable being well under this rating. I got the hammock today, however, and both the paper tag and printed instructions on the stuffsack say the max weight is 180lbs. Luckily I'm also under the 180lb mark, but I could see some 185lb customers being very surprised/irritated by the discrepancy.
So which rating is correct? Will it void my warranty if I let a 190lb friend try out my hammock?
Of course now I'm stuck waiting for some warmer weather, so I don't have to climb through a snow bank to set it up.
