Hennessy Hammock Expedition Asym Zip Review (2026)

Name: Hennessy Hammock Expedition Asym Zip
Brand: Hennessy Hammock
Price: 180.00 USD
Availability: InStock
Rating: 9.0 (1 reviews)

The Hennessy Expedition Asym Zip solves a problem most hammocks don't: getting in and out without letting a downpour or a swarm of mosquitoes in with you. The bottom-entry zip, a signature Hennessy design since the 1990s, means you slide in through the floor rather than pushing through the bug net from the side, so the netting never has to fully open to outside air. It's heavier than a bare ENO setup, but it's a complete, storm-ready shelter system, not just a piece of fabric between two trees.

Common Questions

What is bottom-entry on a hammock?

Bottom-entry means you climb in and out through a zippered opening in the floor of the hammock rather than through the side bug netting. It keeps the netting sealed against rain and insects even while you're getting in or out.

Does the Hennessy Expedition come with a rainfly?

Yes — the asymmetric rainfly is included in the kit, along with webbing suspension straps and carabiners, making it a complete weatherproof setup out of the box.

Is bottom-entry harder to learn than a standard hammock?

It takes a night or two of practice compared to a simple gathered-end hammock with side-zip netting, but most users find it becomes second nature quickly and prefer the weather sealing it provides.
