  Product Description
The Outwell Sleepnest Double self-inflating mat brings proper comfort to tent camping without the bulk you'd expect from a 10cm thick mat. Measuring 200 x 130cm, it provides enough space for two adults to sleep comfortably, with clever zoned support areas and integrated cut-outs that reduce weight while maintaining support where your body needs it most. The double Flat High-Flow valve speeds up inflation and deflation compared to standard valves, which becomes important when you're setting up camp in fading light or packing away in a hurry. The TPU construction with stretch polyester creates a stable sleeping surface that won't delaminate like cheaper foam mats can after a season or two of use.

This mat uses 3D shaping with extra-large foam cavities that compress down more efficiently than traditional flat foam construction, which explains how it packs to 70 x 30cm despite being 10cm thick when inflated. The 30D stretch fabric on top and sides feels comfortable against skin without needing an additional sheet, while the tougher 190T 75D bottom fabric handles rough groundsheets and tent floors. At 5.8kg it's not light enough for backpacking, but that weight brings genuine comfort for car camping, caravan awning use or motorhome trips where you're not carrying gear far. The mat self-inflates when you open the valve, though you'll likely want to add a few breaths to get it fully firm.

One consideration is the packed size - at 70 x 30cm it takes up similar space to a small tent bag, so you'll need decent storage space in your vehicle or caravan. The mat comes PFAS-free, which matters if you're conscious about chemical treatments in camping gear. The included carry bag has compression straps that help with storage, though getting it back in neatly takes practice like most self-inflating mats. Outwell backs this with their reputation for producing camping gear that holds up across multiple seasons, and the TPU construction should resist the punctures and wear that typically end cheaper mats' lives after a few trips.

Frequently Asked Questions

How does the Outwell Sleepnest Double compare to standard 10cm self-inflating mats?
The Sleepnest Double uses TPU construction rather than traditional foam laminate, which prevents delamination that occurs when the foam layers separate from the outer fabric after repeated use. The 3D shaping with extra-large foam cavities allows better compression than flat foam construction, so it packs smaller relative to its 10cm inflated thickness. The double Flat High-Flow valve system moves air faster than single-valve designs found on most competing mats in this thickness range.
What's the actual packed size of the Outwell Sleepnest Double 10cm mat?
The mat packs to 70 x 30cm when rolled and stored in the included carry bag with compression straps. This is similar in size to a small three-person tent bag, so you'll need adequate storage space in your car boot, caravan locker, or motorhome garage. The packed size reflects the mat's 10cm thickness and 200 x 130cm dimensions when inflated.
Is the Outwell Sleepnest Double suitable for backpacking or wild camping?
At 5.8kg weight and 70 x 30cm packed size, this mat is designed for car camping, caravan awning use, or motorhome trips where you're not carrying gear long distances. The weight and bulk make it impractical for backpacking or wild camping where you need to carry everything on your back. For those activities, lighter inflatable or closed-cell foam mats work better.
Does the Outwell Sleepnest Double self-inflate fully on its own?
The mat self-inflates when you open the double Flat High-Flow valve by drawing air into the foam structure as it expands. This process typically takes 5 to 10 minutes depending on temperature, as cold conditions slow foam expansion. Most users add several breaths through the valve to achieve full firmness and proper support. The self-inflation gets the mat to about 80 to 90 percent of full inflation without manual input.
What does PFAS-free mean for the Outwell Sleepnest Double mat?
PFAS-free means the mat contains no per- and polyfluoroalkyl substances, which are synthetic chemicals sometimes used in water-resistant and stain-resistant treatments for outdoor gear. These chemicals persist in the environment and accumulate in human bodies over time. Outwell manufactures this mat without PFAS treatments, using alternative methods to achieve the necessary water resistance and durability for the TPU coating and polyester fabrics.
How do you deflate and pack the Outwell Sleepnest Double mat properly?
Open both parts of the double Flat High-Flow valve fully and roll the mat from the opposite end to the valves, which pushes air out efficiently. Apply pressure while rolling to compress the foam and expel remaining air. Once rolled tightly, close the valves to prevent air re-entering, then secure with the carry bag's compression straps. Getting a neat pack takes practice as the 10cm foam wants to expand, so rolling firmly and using the compression straps properly makes storage easier.
Can you repair punctures in the Outwell Sleepnest Double if it gets damaged?
The TPU construction accepts standard self-inflating mat repair kits that use adhesive patches designed for thermoplastic polyurethane materials. Clean the damaged area thoroughly, apply the patch following the repair kit instructions, and allow proper curing time before reinflating. The TPU material repairs more reliably than PVC alternatives. Small punctures from thorns or sharp stones typically repair well, though large tears or valve damage may need manufacturer service.
What's the difference between the 30D stretch fabric on top and 190T 75D fabric on bottom?
The 30D stretch fabric on the top and sides uses thinner denier polyester that stretches with body movement for comfort and feels soft against bare skin without needing additional sheets. The 190T 75D bottom fabric uses thicker denier polyester with tighter weave for abrasion resistance against rough tent groundsheets, caravan awning floors, and stones that might work through groundsheets. This two-fabric approach puts durability where needed while keeping the sleeping surface comfortable.
