I suppose a soap bubble would be lighter. Plastic wrap too. Maybe freshly spun spider silk? All I know is that the Sea to Summit Ultralight Hammock is so light it barely exists. You can’t help but let out a little chuckle to yourself when you unfurl it from its compression sack. It’s like a suggestion of a hammock. 5.4 ounces of virtually nothing.

Well, not nothing. It’s constructed from Nylon 66 monofilament ripstop fabric. Just hardly any of it. It weighs less than a baseball.

It’s eight and a half feet long by four feet wide. I’m a hair over 6’1″ and I found the hammock to be perfectly long. If I was 6’5″? Probably not so much. As with all lightweight hammocks, you end up folded up in the thing as though you’re the tobacco in a rolled up cigarette. Still though, the Sea to Summit is as pleasant as could be. I mean, it’s a hammock. As far as I know, the word “hammock” is a Finnish or maybe Native American word for “pleasant.”


Of course you need straps for the hammock, and, also as usual, they weigh more than the hammock itself. In this case, 3 ounces each. Wound up like a donut though, they fit nicely in the hammock’s compression sack. The buckles are made from a lightweight aluminum, even further shedding ounces. Setup is easy and pretty standard: Wrap the straps around a tree, pull a buckle through a loop in the strap, insert the buckle in a strap on the hammock’s end. Sea to Summit also throws in tree protectors with the suspension straps, though they’re not necessary if you’d prefer to leave them home. You also get a patch kit with a few pieces of the hammock material. Hopefully that’s not necessary either.

According to Sea to Summit, the hammock can support 300 pounds and the straps can hold 400 pounds. I’m sure they’re right, but there’s no reason to worry. This thing may be ethereal, but when you get to laying in it, it feels plenty strong.

Sea to Summit advertises this UL hammock as the lightest in the world, and if they’re wrong, well, I’m not sure how that would be possible. For an UL backpacker who sleeps in a hammock, this is about as UL as it gets. There are more comfortable hammocks out there, but the weight savings are probably worth it. If you just like the idea of resting in a hammock at a backcountry site but still prefer to sleep in a tent? This thing is light enough to pitch into your pack as an afterthought.

Plus, if you get the grey color, it’s on sale for only $55.
