When eno says XL, as in the Atlas XL Suspension system they don’t mean “bigger bodies” they mean a longer length. The XL is 13 feet, 6 inches, as opposed to the 9 feet of the regular, for an additional 54” in length for those situations where the trees are.. tubby. Or the length apart is a bit greater. With 40 combined attachment points this can be snugged down for smaller trees and shorter distances, but deployed to breach situations where more length is required. You’re trading flexibility in length for weight, this comes in at 4 ounces heavier than the Atlas. Only you can decide if the added flexibility is worth the extra weight. A no-knot system makes the eno hammocks fast to deploy and quick to take down without struggling with tightened knots, ground cloths, or flyaway tents. Reflective stitching gives you nighttime visibility, although you’re a whole lot less likely to walk smack into your hammock than you are to trip over a guy line. A fast and easy solution to hanging a hammock the Atlas XL will have you up, and snoozing, in no time flat.
