Hennessy Hammock 4Season Survivorman Zip XL M346 review

The Hennessy 4Season Survivorman Zip XL is the most heavily equipped of the brand’s reviewed XL 4Season hammocks. The exact US listing combines a side-entry, two-layer hammock body with an open-cell foam pad, an attached insect screen, stock rainfly, ropes, tree webbing and a Survivorman survival kit. Its extra load margin and included pieces distinguish it from the 4Season Explorer XL, but they come with a heavier and less precisely documented carry package. This is a source-based assessment of the manufacturer’s published material, not a field test.

What changes from the 4Season Explorer XL

Both XL models use a 70D-and-40D two-layer nylon bottom, list a 130-by-59-inch fabric body and have a seven-foot user-height limit. Hennessy’s current US page rates the Survivorman to 350 pounds and lists its polyester suspension ropes at 2,100-pound test; its comparison chart gives the Explorer XL a 300-pound hammock limit and 1,800-pound-test ropes. Those figures describe the hammock or individual rope specification, not the capacity of every strap, anchor, tree or complete hanging system.

The Survivorman listing also says its oversize open-cell foam pad and survival kit are included. It names a bright orange Survivorman bandana with printed tips, and says the kit contains a space blanket, but the US product page does not inventory the kit’s other pieces or give the pad’s dimensions and weight. That explicit pad inclusion is stronger than an Explorer listing that explains the pad arrangement without clearly itemizing it in the included-items text. Before purchase, confirm that the actual M346 offer still contains the pad and a complete kit; do not treat the kit name as a guarantee of a particular emergency capability.

Layers, insects and rain are separate jobs

The double bottom is meant to hold the foam pad on the diagonal and can also hold additional improvised insulating material. That gives the package a defined underbody-insulation arrangement rather than requiring the buyer to start with a separate pad. It does not establish a temperature rating. The page describes a 30D No-See-Um mesh enclosure and a side-entry #10 YKK double-slider zipper, while its detachable 70D Hex Fly is a distinct overhead weather layer. A fly can limit exposure to rain; it is not body insulation, and the net is not a rain cover.

Hennessy lists the stock hexagonal fly at 143 inches along the centerline by 120 inches wide. Its suspension description includes two ten-foot polyester-covered ropes, standard 2-inch-by-42-inch webbing and the fly. The listed 2,100-pound rope test and strap specifications are component details, not permission to exceed the hammock limit or use unsuitable anchors. Check your campsite’s permitted attachment points, span and tree-protection requirements; 42-inch straps will not fit every tree or every setup.

Carry weight and packing sequence

Hennessy lists packed weight as 5 pounds 9 ounces (2,548 grams), expressly excluding the 4-ounce webbing straps. Its comparison chart repeats the same packed figure. The paired Shopify variant record, however, stores a generic 2,625-gram variant weight without defining whether it is a shipping value or which components it includes. The listed packed figure is therefore useful as the maker’s stated baseline, not a measured all-in mass for every item you will carry. Add the omitted webbing and any personal sleep or repair equipment only after checking the actual package contents.

The stated packed dimensions are 16 by 8 by 8 inches. Hennessy’s 4Season instructions describe keeping the hammock and foam pad together in the compression sack and storing the wet rainfly separately in SnakeSkins. The page recommends pitching the rainfly first in rain, then setting up the hammock underneath it. SnakeSkins are not clearly itemized in the included-items section, so verify whether they are part of the offer or a separate accessory before relying on that packing method.

Who may prefer it—and who may not

This model makes most sense for a buyer who wants a screened XL hammock, a higher published hammock-body limit than the Explorer XL, a supplied foam-pad arrangement and a bundled emergency-kit concept in one named configuration. The reversible orange interior is presented by Hennessy as a search-and-rescue signal feature. Those additions may be worthwhile for a deliberate preparedness setup; they are less compelling if you already carry equivalent equipment or are minimizing pack weight.

The Survivorman is not a lightweight shortcut: its published packed figure is over five pounds before the separately stated webbing. Nor does the “4Season” name promise comfort in every season. Match the complete insulation plan to the forecast, ground and body-specific needs, and do not rely on an untested temperature claim. Confirm the exact SKU M346, current pad and survival-kit contents, fly, straps, SnakeSkins status, setup instructions and return/warranty terms. The 130-by-59-inch body dimensions and seven-foot height limit are manufacturer references, not a promise of personal comfort or required tree spacing.
