Hennessy Hammock Safari Deluxe Zip XXL Woodland M166 review

This is a source-based assessment of Hennessy Hammock’s US Safari Deluxe Zip XXL Woodland, product 7089298473029, SKU M166 and UPC 832667000785. I have not owned, slept in, measured or load-tested it. I compared its exact manufacturer listing and Shopify record with Hennessy’s M66 standard-color Safari listing, comparison chart and separate custom builder. The central buying question is not simply “how big is it?”: M166 is a 12-foot-listed XXL body with an integrated screen and broad stock fly, but the same product page gives conflicting lengths for its included tree webbing.

Woodland M166 is not the standard-color M66

Hennessy identifies the Woodland hammock as SKU M166. Its model-specific description calls out a larger Hex rainfly and longer TreeHuggers; it also describes the body as the company’s deepest and widest hammock. The M66 Safari Deluxe Zip XXL shares the listed 144-by-59-inch lower fabric, seven-foot height limit, 350-pound hammock limit, side zipper, mesh and 143-by-120-inch hex-shaped fly dimensions. M166’s reviewed package is still a distinct retail configuration: Woodland camouflage and M166, not the standard-color M66 listing. Its longer-webbing claim is the potentially useful package difference, but it is not consistently stated on the page.

Do not confuse either fixed package with Hennessy’s separate “Customize your Safari Deluxe Zip” builder. That listing starts with a hammock body and selected webbing and presents fly and insulation choices separately. A model name shared across these offers does not make their starting packages interchangeable.

The XXL measurements are useful screens, not a comfort promise

The exact M166 page lists lower fabric at 144 by 59 inches. The length converts to 12 feet, and Hennessy gives an upper user-height figure of seven feet and a 350-pound hammock-body limit. These are manufacturer screening values; they cannot tell a particular sleeper whether the diagonal lay will feel right, how much usable room there is, or what anchor spacing a site requires. The page’s description of couples staying within the combined limit remains a maker claim, not an independent two-person comfort assessment.

The 2,100-pound figure is a test claim for the listed suspension ropes, not a system rating. It cannot be transferred to the hammock, webbing, connectors, trees, stand or anchor path. Check every component and the instructions for the actual setup, keep within the lowest applicable limit, and use sound, permitted supports. A 12-foot fabric body also does not mean that any 12-foot tree gap is suitable.

Screen, fly and warmth are separate jobs

M166 is a side-entry design with a heavy-duty #10 YKK zipper and two sliders. Its specification lists 30D No-See-Um netting, a structural ridgeline and an asymmetrical body. The included rainfly is described as a large Hex, with stated dimensions of 143 inches along the centerline and 120 inches across; the product photo shows the Woodland pattern above the hammock body and mesh. These source details describe the package and design, not an insect-proofness test, waterproof rating, wind test or guarantee of coverage in every pitch.

The listing does not include underbody insulation. A roof can limit rain exposure, and mesh can provide a barrier against insects, but neither makes the underside warm. If a trip needs insulation, identify a compatible pad or underquilt separately and plan for the forecast. The product’s SnakeSkins and other packing options should likewise be checked as offer-specific accessories rather than inferred from the hammock photo.

The included-webbing length needs confirmation

The M166 page first says that the Woodland model includes longer 72-inch webbing. Its detailed specification calls the straps 1.5 inches by 72 inches / 3.8 by 182 centimeters. Yet the same page’s generic included-items paragraph says the complimentary “Tree Hugger” webbing is 42 inches / 107 centimeters. I can confirm from the page that webbing is represented as included; I cannot resolve the actual M166 length from those contradictory statements. Ask Hennessy or the seller to confirm the exact straps in the M166 package before deciding based on tree diameter, spacing or suspension length. Do not silently substitute a custom-builder option or another Safari SKU.

Published mass figures are not a verified carried weight

Hennessy lists packed weight as 4 pounds 4 ounces / 1,904 grams, excluding the free webbing, which it separately gives as 8 ounces / 234 grams. Those imperial and metric pairs do not convert exactly. There is no independent measurement here, and no settled all-in mass for the hammock, fly, webbing and any optional packing accessories. I therefore do not use the page’s numbers to rank M166 against lighter models or promise a backpack weight. The listing also gives a 5-by-8-by-12-inch packed size; that is a manufacturer claim, not a pack-volume test.

A cosmetic-second offer shares M166 identity, not a known defect description

A separately observed 2026 “Cosmetic Second” listing uses M166 and the same UPC as the standard Woodland offer. Its page says that free SnakeSkins are included, while the exact cosmetic flaw is neither described nor shown in a way that identifies this individual item. The base M166 feature assessment can cover the hammock model, but a shopper considering that sale offer should request the particular defect, current condition, package contents and return terms. Its separate seller offer is not evidence that every standard M166 includes the same accessories.

Who should compare it and what to verify

M166 belongs on a shortlist when the requirements truly include a long XXL-listed body, integrated screen, included broad hex fly and the maker’s 350-pound hammock limit. The M66 review is a useful comparison for the same listed lower-fabric dimensions and capacity, while the custom Safari builder is relevant only if selecting webbing and adding a fly separately suits the purchase. None of those comparisons supplies a field trial, fit guarantee, weather test or complete-hang rating.

Before ordering, confirm M166 and the Woodland edition in the final offer; ask whether the included TreeHugger straps are 42 or 72 inches; verify the fly, screen, ropes and sack in the exact package; and ask the maker to clarify the packed-weight and conversion discrepancies if weight matters. For a cosmetic-second item, also verify the individual flaw and condition. Read the current setup instructions, check the suitability of the actual anchors and suspension, and plan underbody insulation separately. This assessment is a careful reading of published evidence, not a claim of personal use or a guarantee that an offer is in stock.
