If you’re trying to decide between the Esme L&H Mattress Underlay and the Kingnex Cooling Bamboo Viscose Mattress Protector for your RV, you’re really choosing between two completely different approaches to breathability. The Esme L&H uses a super breathable 3D mesh fabric that’s 0.39 inches thick, while the Kingnex relies on natural bamboo viscose fibers to wick moisture away.
This comparison is for anyone who wakes up to a damp mattress in their camper or trailer. The key trade-off here is airflow versus waterproof protection. Let me break down exactly how these two perform so you can pick the right one for your setup.

This Esme L&H underlay is the clear winner for breathability thanks to its 0.39-inch thick 3D Air Mesh fabric with large honeycomb holes that let air and water flow freely. I love that it comes with four corner elastic bands and bound edges, so it stays put on my camper bed without shifting around all night. The only downside is it’s hand wash only, which is a bit more work than tossing something in the machine. This is perfect for anyone dealing with moisture buildup in their RV or trailer who wants maximum airflow.
✅ Pros
- 0.39 inch thick 3D mesh creates serious airflow gaps
- 4 corner elastic bands keep it anchored on RV beds
- Lightweight, foldable, and comes with a storage bag
- Rated 4.6 out of 5 stars from 32 reviews
❌ Cons
- Hand wash only, no machine washing
- No waterproof protection for spills or accidents

The Kingnex protector takes a different approach to breathability by using natural bamboo viscose fibers that wick moisture and regulate temperature, and it has a waterproof TPU backing to block spills and sweat. I found it to be noiseless with no crinkly plastic feel, which is impressive for a waterproof cover. The stretchy skirt and elasticized edges fit deep mattresses well, but the breathability here is more about moisture wicking than actual air movement through the pad. This is a solid choice if you need waterproof protection but still want some cooling properties.
✅ Pros
- Waterproof TPU backing stops spills and sweat completely
- Bamboo viscose blend wicks moisture and feels cool
- Machine washable for easy care
- Rated 4.5 out of 5 stars from 699 reviews
❌ Cons
- Not as much direct airflow as the 3D mesh Esme underlay
- No corner straps — relies on elastic skirt fit
Which One Should You Buy?
I’ve spent a lot of time thinking about these two, and honestly, the right pick comes down to whether you need maximum airflow or waterproof protection. Here’s who I’d recommend each one for.
Esme L&H Mattress Underlay RV is right for you if…
- You wake up to a damp mattress in your RV and need serious airflow — the 0.39-inch thick 3D mesh with honeycomb holes lets air and water flow freely through it.
- Your mattress shifts around while you sleep and you want something that stays put — the four corner elastic bands and bound edges keep it anchored.
- You need a lightweight, portable option that folds up small and comes with a storage bag for travel or seasonal storage.
Kingnex Cooling Bamboo Viscose Mattress Protector is right for you if…
- You’re worried about spills, sweat, or accidents ruining your mattress — the TPU membrane backing is completely waterproof.
- You want cooling without sacrificing protection — the 55% bamboo viscose blend wicks moisture and regulates temperature while still blocking liquids.
- You prefer machine washing over hand washing — this protector is machine washable on cold, while the Esme is hand wash only.
❌ Who Should Skip All of These?
If your mattress is already in good shape and you just want a basic sheet or pad for comfort, neither of these is what you need. These are specialty products for moisture management and protection, not for adding plushness or changing the feel of your bed.
For most RV owners dealing with moisture buildup, I’d grab the Esme L&H underlay — that 0.39-inch 3D mesh is simply the best way to keep air moving under you and stop dampness before it starts.
Frequently Asked Questions
Which is more breathable for an RV mattress — the Esme L&H or the Kingnex?
The Esme L&H is hands-down more breathable because of its 0.39-inch thick 3D Air Mesh fabric with large honeycomb holes that let air and water flow freely through the pad. The Kingnex uses bamboo viscose fibers to wick moisture, but it also has a waterproof TPU backing that traps air and prevents the same level of ventilation. If your main concern is airflow to stop mold and mildew, I’d go with the Esme every time.
Is the Kingnex waterproof mattress protector worth buying over the Esme underlay?
It depends on what you need. The Kingnex has a TPU membrane coating that makes it completely waterproof, so it’s the right choice if you’re worried about spills, sweat, or accidents damaging your mattress. The Esme L&H has no waterproof layer at all — it’s designed for ventilation, not liquid protection. If you need both breathability and waterproofing, you might actually want to use the Kingnex as a protector and the Esme as a base layer underneath.
Which one stays in place better on an RV bed?
The Esme L&H wins here because it has four corner elastic bands plus bound edges that anchor it securely to your mattress, which is especially valuable for camper beds and trailer setups where things shift around. The Kingnex relies on a stretchy skirt and elasticized edges around the perimeter, which fits well but doesn’t lock into the corners as tightly. For bumpy roads and tight RV spaces, I trust the Esme’s corner straps more.
Can I machine wash these mattress underlays?
Only the Kingnex is machine washable — just wash it on cold and tumble dry low, and don’t iron or dry clean it. The Esme L&H requires hand washing only, which is a real inconvenience if you want to clean it regularly. If easy maintenance is a priority for you, the Kingnex is the much more practical choice.
Which one is thicker — the Esme L&H or the Kingnex?
The Esme L&H is 0.39 inches thick, which is significantly thicker than most underlays and gives it strong resilience that won’t easily deform over time. The Kingnex doesn’t list a specific thickness in its specs, but as a fitted mattress protector it’s much thinner and closer to a standard sheet. If you want actual cushioning and space for air to move, the Esme is the thicker option by far.
Which product has better customer reviews?
The Kingnex has a 4.5 out of 5 star rating from a massive 699 reviews, so there’s a lot of real-world feedback backing it up. The Esme L&H has a slightly higher 4.6 out of 5 stars but only from 32 reviews, so the sample size is much smaller. I’d trust the Kingnex’s track record more simply because more people have tested it, but early buyers of the Esme seem very happy with the breathability.
My Final Verdict
The Esme L&H Mattress Underlay is my clear winner for breathability — its 0.39-inch thick 3D Air Mesh fabric with honeycomb holes creates real airflow that the Kingnex’s waterproof TPU backing simply can’t match. The Kingnex is a solid runner-up if you need waterproof protection with bamboo viscose cooling, but for pure ventilation to stop moisture buildup in an RV, the Esme takes the crown.
If you’re still on the fence, ask yourself this: are you dealing with a damp mattress and worried about mold, or are you more concerned about spills and stains? That single question will point you to the right product every time.
