The Sub6 is defined by one astonishing number: 5.8 ounces, less than most phone-and-wallet combinations. For gram-counting backpackers, that figure ends the conversation — nothing else in the mainstream hammock market is close. The engineering that gets it there is genuinely clever: a 30D ripstop body that still holds 300 pounds, and an aluminum toggle suspension that keeps the entire hang under half a pound when paired with ENO's Helios straps. At $70-80 the price of admission to true ultralight is also surprisingly reasonable. The trade-offs are proportional to the weight savings, and they are not small. The 9-foot by 4-foot cut is narrow — there is no diagonal sprawl, and larger campers will feel confined. There are no pockets, no frills, nothing but hammock. The thin fabric demands care around sharp bark and rough handling that heavier hammocks shrug off. And like most ENO products, straps are sold separately, so budget for suspension before your first hang. This is a specialist's tool: a fair-weather, bug-free-season luxury for backpackers who measure their base weight in grams. For that camper it is nearly perfect. As an only hammock or a lounging hammock, the wider, tougher picks above it are the better life choice.
