Outwell Sleepin 5cm Single Self Inflating Mat

Materials & Waterproofing

The Outwell Sleepin 5cm Self-Inflating Camping Mat is built to handle repeated outdoor use without compromising comfort. The surface and base are made from durable 190T 75D polyester, offering abrasion resistance and easy maintenance. While not waterproof like a tent floor, the material resists moisture and dries quickly, making it suitable for damp ground or tent floors. The airtight fabric casing ensures effective self-inflation and long-term reliability.

Stability

Unlike traditional airbeds that rely on external support, this mat uses an open-cell foam interior for structure and firmness. The foam expands evenly when unrolled, offering consistent support across the full surface. It’s stable enough for side-sleepers and doesn't shift around easily, even on uneven terrain. The design eliminates the bouncy feel of air beds, improving sleep quality outdoors.

Sleeping/Living Space

With dimensions of 183 x 63 x 5 cm, the Sleepin 5cm mat provides generous length and width for one adult. The 5cm thickness adds a layer of insulation and comfort between you and the ground, making it suitable for use directly on tent floors or hard surfaces. The rectangular shape maximizes usable space without unnecessary bulk, ideal for smaller tents or tight sleeping quarters.

Comfort

Thanks to the open-cell foam core, the mat not only offers cushioning but also retains some warmth - important during colder nights. Unlike air-only mats, it reduces the chance of feeling cold from below. Breathability is enhanced by the polyester fabric, which doesn't trap heat or moisture, helping maintain a dry and comfortable sleeping environment.

Pitching & Pack Size

Setting up the Sleepin 5cm couldn’t be easier. Just unroll the mat, open the Outwell Flat High-Flow (FHF) Valve, and let it do the work. Inflation takes only a few minutes, and the low-profile valve allows for easy topping up or rapid deflation. When packed down, it measures just 32 x 21 cm and fits neatly into the included carry bag - perfect for lightweight campers or those with limited space. Weighing just 1.5 kg, it strikes a great balance between comfort and portability.
