I haven't broken a WW DL hammock... so this is PURELY conjecture (well, mostly conjecture based on testing of the model in a single layer and the results of that)...
I'd be comfortable recommending this to anyone up to 300. The DL adds reinforcement at the seams, with the fabric, etc. In other words, my only hedge on this at that weight would be making sure you had a good suspension system. If you do... should be good to 300.
Now carrying the Mini Tattoo Stove!
Light weight. Low prices. Great gear.
