Hennessy custom 4Season Explorer Zip XL, P336E body plus selected TreeHugger webbing review

The Hennessy custom 4Season Explorer XL Zip is a body-builder listing, not the fixed M336 package shown on the standard product page. Its first step pairs a P336E hammock body with one selected TreeHugger webbing length and says to order without a rainfly. A model-specific fly is a later option. That package distinction is the most important buying detail: the custom listing can suit someone choosing their suspension length, but its base step is not a ready-made overhead shelter kit.

Separate the custom body from the stock M336

The exact custom page lists one of three webbing choices: 42, 72 or 96 inches. The paired product record identifies them as P336E+P213, P336E+P216 and P336E+P220. These are mutually exclusive selections for one body, not three hammock models. By contrast, Hennessy's standard 4Season Explorer Zip XL M336 page describes a hammock ordered with a stock rainfly and 42-inch webbing. Its package contents and weight figures should not be copied onto this custom body-only first step.

The builder calls its optional Step 2 fly an Explorer Deluxe Rainfly 70D Polyester. That compatible overhead shelter is not in the base body-plus-webbing choice. A separate optional insulation-system step follows, while the builder also says the 4Season already includes insulation specially designed for the hammock. That wording signals a two-layer, pad-oriented design, but it is not a list of the pieces in a cart. The standard M336 description discusses an oversize open-cell foam pad and a space blanket without explicitly itemizing either in its generic inclusion block. Confirm the final custom order's pad, space blanket, fly and any other selected components rather than relying on the model name or image.

What the 4Season design does—and does not—tell you

For the same named Explorer XL body, Hennessy's M336 specification page lists one 70D nylon layer and one 40D layer, with the lower fabric measuring 130 by 59 inches. The custom builder itself does not repeat those dimensions, so treat them as shared-model body specifications, not measurements of the whole packed kit. They do not guarantee comfort for a particular sleeper or give the span required between anchors.

The standard model page describes a pad between the layers and estimates that, with an oversize open-cell pad, “most people” may be comfortable to about 40°F. It says a space blanket may extend that arrangement below freezing. Those are Hennessy's conditional estimates, not our test results or a promise for every person or weather situation. The custom builder does not name the pad contents or attach a temperature rating to its base cart. Plan the full sleep system independently and confirm which insulation pieces the chosen offer actually supplies.

XL limits, Zip entry and body capacity

The exact standard M336 page lists the XL model for users up to 7 feet tall and gives a 300-pound hammock limit. The custom builder names the same 4Season Explorer XL Zip body but does not restate either limit; check the current offer and the maker's instructions. The 300-pound number is a hammock-body limit only. It does not rate the selected webbing, any suspending rope or connector, trees, anchors, a stand or the complete hang.

The exact builder identifies this as the Zip version. Hennessy's features and FAQ pages distinguish its side-zip mesh entrance from the Classic model's bottom entrance. That supports an integrated-net design, but the custom listing does not state a mesh denier or establish that every zipped opening is insect-proof in every setup. The side closure and 4Season double layer also make this a more involved system than an open, single-layer hammock; if simple warm-weather lounging is the goal, the extra choices may not be useful.

Choose webbing from the actual site, not a table alone

The custom builder pairs its 42-, 72- and 96-inch webbing choices with tree-diameter examples of 14, 24 and 36 inches. The manufacturer's separate features page gives 24 inches for 72-inch webbing but prints “32'” for the 96-inch example, which conflicts with the custom builder and is not safely normalized to inches here. Neither page is a safe-fit calculation. Consider the anchor's condition, the complete wrap and the suspension instructions; confirm that the selected webbing works for the actual permitted site.

The builder does not clearly itemize the full suspending ropes or give a credible packed weight for this custom configuration. Its product record contains mutually inconsistent weight metadata; the separate M336 page and comparison chart also disagree about the fixed package's packed weight. Since the fly, optional insulation and webbing length can change the cart, none of those figures establishes this custom kit's all-in carry mass. Ask the manufacturer for a reconciled package list and weight if either is essential.

Who should shortlist this configuration

This body-builder is worth comparing if you specifically want an XL side-entry 4Season hammock, want to select among three webbing lengths and are comfortable assembling the remaining shelter and insulation pieces from confirmed parts. It is a poor shortcut for someone who needs one clearly itemized, fly-equipped package or a dependable packed-weight total. The right comparison is not “4Season versus three-season” by label alone: verify the exact body, chosen straps, fly, pad and sleep layers for the trip.

This assessment is based on Hennessy's custom P336E builder, its separate standard M336 page, and the manufacturer's comparison chart, features guidance and FAQ. It is research-based, not a report of ownership, setup, camping use or cold-weather testing. Check the exact selected variant, final cart and current directions before relying on any part of the system.
