Exped Doublemat Evazote Review

Overview

The Exped Doublemat Evazote is a large-format, closed-cell EVA foam pad that does double duty as both a tent floor liner and a folded sleeping mat. It’s designed to be used as both a tent carpet (fully rolled out) and a single-person sleeping mat (doubled over). At 260g for a 200x100cm sheet, it punches well above its weight class in surface area — but whether that translates to a useful sleep system depends almost entirely on how you intend to deploy it.

Performance

Insulation — Know What You’re Buying

The first thing to understand about this pad’s R-value is that the headline number of 1.2 only applies when the mat is folded in half. The stated R-value of 1.2 is misleading, as it’s for when the mat is doubled over — fully opened up as a single layer, the R-value drops to just 0.6. Put bluntly: this is not a standalone three-season pad. As a solo sleeper on a summer night above 10°C, folded, you’ll be fine. Below that, you’ll want a proper inflatable underneath — and that’s actually where the Doublemat shines.

Many users carry it as an extra underlay under inflatable pads for extra insulation, or as a backup if their primary pad fails.

Stacked beneath a NeoAir or similar inflatable, the R-value bump is modest but real, and the closed-cell foam protects the inflatable from punctures on rough ground.

Under an inflatable pad, it protects from stabby things in the ground and keeps the sleeping pad from sliding around.

Versatility — Its Actual Selling Point

The Doublemat can be used as an insert into the bottom of a mat cover for added protection and insulation, or folded as a single mat at 8mm, with the option of stuffing clothing between the layers for extra warmth — or laid out flat at 2m x 1m as a ground layer under an ultralight inflatable.

That range of use cases is genuinely practical on expedition-style trips. I’ve seen people use these as a sit pad outside the tent, a changing mat, a picnic blanket, and a camp chair base — all before it ever becomes a sleeping surface.

Durability — Outstanding

Made of Evazote, an environmentally sound closed-cell EVA foam optimised for expedition use, it’s acclaimed for extreme durability and is not rendered useless by thorns, debris, or crampons.

That claim holds up.

After more than ten years of use, one owner reported that the pad was just starting to get a little thinner in places — not tears or holes, just minor compression.

That’s a remarkable lifespan for a piece of gear that costs relatively little. Quality control appears solid too:

there are no pin holes and the thickness of the pad is uniform throughout.

The smooth surface of Evazote pads doesn’t collect snow or water like the ridged surfaces of a RidgeRest or Z-Lite.

That’s a small but real advantage in wet or snowy conditions. The black color also makes it quick-drying.

Packability

At full size it’s 200x100cm — gigantic — but it hardly takes up any space packed anyway.

The 51x15cm packed size is genuinely compact for what you get. It rolls into its included stuff sack easily and could slip into an external mesh pocket or strap to the back of a pack. The width-to-weight ratio is unusually generous: you’re getting a pad wide enough to sleep on without worrying about rolling off, at a weight that would normally buy you a narrow torso pad in other materials.

Comfort

Four millimetres of foam is four millimetres of foam. Doubled over to 8mm, it’s adequate for back sleepers on smooth ground, but side sleepers with any hip sensitivity will feel the deck beneath them by morning. Don’t expect the cushioning of even a budget inflatable. This is a pad for people who’ve made peace with minimalism, or who are pairing it with something softer.

Customisability

Owners commonly cut the pad to fit, resulting in two pieces of approximately 50x180cm each — still perfectly usable as individual sleeping pads.

Some users cut it down to fit under an inflatable like the NeoAir X-Lite; others specifically chose this pad because it comes in a full-length 200cm, compared to shorter competitor options.

Easy scissor-trimming is a genuine advantage over more structured pads.

Pros & Cons

Pros

• Exceptional weight-to-surface-area ratio — 260g for a full 200x100cm sheet
• Virtually indestructible; resists punctures, thorns, and crampons
• No inflation needed, no valve to fail, no pump
• Smooth surface sheds water and snow; quick-drying black finish
• Extremely versatile: tent liner, ground cloth, inflatable underlayer, seat pad
• DIY-friendly — scissors-trimmable to any shape or size
• Ships with a stuff sack; packs to just 51x15cm

Cons

• R-value of 1.2 only applies when folded — 0.6 flat is barely worth measuring
• At 8mm folded, comfort is minimal; not a standalone option for side sleepers or cold conditions
• Rolled dimensions are wide; not ideal inside a slim ultralight pack
• Some retailers list it as discontinued — check availability before ordering
• Minimum standalone use temperature of ~10°C makes it a true warm-weather-only solo option

Who Should Buy This

The Doublemat Evazote makes the most sense for three types of hikers: those who want a bombproof inflatable protector and anti-slip base layer (particularly on silnylon tent floors); those doing expedition or alpine trips who need a zero-failure-mode backup pad; and ultralight pack-rafters or kayakers who want one piece of gear that covers sleeping, sitting, and kneeling surfaces. It’s also a smart buy for anyone who regularly shares a tent and wants a wide ground layer under a double-wide inflatable setup.

It’s not the right pick for someone expecting a solo three-season pad out of the box. The R-value ceiling is simply too low for that role.

Verdict

The Exped Doublemat Evazote is a niche piece of gear that does its intended job extremely well — as long as you’re honest with yourself about what that job is. Treat it as a multi-purpose foam layer, a durable protector for your inflatable, and a reliable backup in a system, and it earns its 260g easily. Try to use it as a standalone three-season sleeping pad and you’ll be cold and disappointed. I’d rate it 7/10 — high marks for durability, versatility, and weight efficiency, but the R-value limitations keep it from being a wider recommendation.
