Head-to-Head: ENO DoubleNest vs. Kammock Roo Double
The Short Answer
After spending the last two seasons swinging between these two heavy-hitters, the choice comes down to your specific sleeping habits and how you plan to use the hammock. Here is how they stack up in the real world.
- Buy ENO DoubleNest Hammock if:
- You prioritize a wider sleeping width to prevent the “sack-out” feeling when you roll over.
- You need a hammock that hangs on a single wide tree or a single spreader bar for a more traditional setup.
- You want a proven brand with extensive repair resources and a vast community of users for advice.
- You prefer a lighter pack weight, as the ENO is generally 300-400 grams lighter than the Kammock.
- Buy Kammock Roo Double if:
- You need a dedicated 2-person space for a partner or a child without compromising comfort.
- You frequently hang on widely spaced trees (over 15 feet apart) where the Kammock’s wide spreader bar provides a massive advantage.
- You want a rigid, wide frame that eliminates the need to sleep “diagonally” or “straight” to get enough width.
- You are willing to carry extra weight for a more rigid, cot-like sleeping platform feel.
Key Differences
The most obvious distinction is the width and the frame geometry. The ENO DoubleNest relies on a single wide bar (or no bar depending on the specific model variation you buy, though the DoubleNest typically uses a wide spreader bar to maintain width) to create a wide sleeping area. The Kammock Roo Double, conversely, utilizes two distinct spreader bars that lock together to form a rigid rectangle. This rigid frame is the single most significant difference, changing the physics of how you sleep.
Weight is another major factor. The ENO DoubleNest weighs in at roughly 4 lbs 1 oz. The Kammock Roo Double tips the scales at approximately 5 lbs 4 oz. That nearly 1.5 lb difference might seem negligible, but over 200 miles of backpacking, it adds up. The ENO fabric is a durable ripstop nylon that feels softer to the touch out of the box, whereas the Kammock uses a slightly thicker, more industrial-feeling nylon that requires a few nights to break in.
Price is a standard differentiator, with the Kammock commanding a premium of about $100 to $150 more than the ENO. However, there is an unexpected difference most buyers miss: the tension points. The ENO’s single bar design concentrates the tension of the suspension on one central point of the bar. The Kammock distributes this tension across two separate bars, which reduces stress on the suspension straps at the connection points, potentially extending the life of your straps if you hang on very wide trees.
Setup speed also varies. The ENO is a “throw and go” system. The Kammock requires a specific locking mechanism for the bars to engage, which takes a few seconds more than the ENO but feels more secure once locked.
Who Each Product Is Best For
The ENO DoubleNest is best for the solo adventurer or couples who sleep in close quarters and don’t mind sharing a sleeping area. It is ideal for car camping or base camp scenarios where weight is less of a concern than comfort. It is also the perfect choice for backpackers who need a reliable, lightweight shelter system but want the extra width of a double hammock. If you are a solo hiker who occasionally wants to bring a guest, the ENO is the safer bet as it can be used by one person with plenty of room to spare.
The Kammock Roo Double is best for families, couples who want their own dedicated space, or anyone who suffers from back pain and needs a rigid, flat surface. It is the superior choice for campers who hang between widely spaced trees (18+ feet) where the ENO would droop significantly. It is also the go-to for treeless environments where you are using a wide spreader bar to create a stable platform. If you value a “cot-like” feel over a traditional hammock sway, this is the only choice.
Performance and Real World Testing
I took the ENO DoubleNest on a 5-day trek through the wet and windy conditions of the Olympic Peninsula. The fabric held up well against constant moisture, though the single bar did flex slightly in high winds, causing a mild rocking motion that some might find unsettling. The biggest weakness I found was the width-to-length ratio. While the width is generous, the length can feel short if you are over 6 feet tall, causing your legs to hang awkwardly or your feet to brush the ground if the suspension is too high. The suspension straps are also a single point of failure; if one tears, the whole hammock goes down.
I tested the Kammock Roo Double on a week-long trip in the Cascades, hauling it over rocky terrain and through dense brush. The rigid frame made a noticeable difference when I sat up; the ENO would sag and shift, while the Kammock held its shape. However, the Kammock’s biggest weakness is its bulk. The wide spreader bars make it difficult to fit into standard hammock gear bags, and the locking mechanism can be finicky if your hands are wet or cold. In a tight tree space, the Kammock can be cumbersome to set up compared to the streamlined ENO.
Quick Comparison Table

|---|---|---|
| Weight | 4 lbs 1 oz | 5 lbs 4 oz |
| Price | $299 | $429 |
| Best For | Lightweight backpacking, solo or shared use | Wide tree spacing, rigid sleeping platform |
| Biggest Weakness | Single bar tension point, shorter length | Bulkier setup, complex locking mechanism |
| Our Rating | 4.8/5 | 4.6/5 |
Price and Value
The ENO DoubleNest retails for $299, while the Kammock Roo Double is priced at $429. While the Kammock offers a premium experience with its rigid frame, the ENO provides significantly more value for the money. For most users, the extra $130 on the Kammock is hard to justify unless you specifically need the rigid frame. The ENO’s lower price point makes it a more accessible entry into the double hammock category. Over the long term, the ENO holds its resale value slightly better due to its ubiquity in the second-hand market, making it a safer financial investment if you decide to sell later.
Which One Should You Buy?
If you are a backpacker who values every ounce and needs a reliable shelter for solo or couple travel, go with the ENO DoubleNest. It is the more versatile tool that fits more scenarios. If you are a car camper, a base camper, or someone who needs a rigid sleeping surface for medical reasons, the Kammock Roo Double is the superior choice despite the extra weight.
