Inflatable Sleeping Mat EXPED Ultra 10R M – self-inflating camping mattress, R-value 10 for cold conditions

EXPED Ultra 10R M is a self-inflating camping mattress engineered for very cold conditions, providing an R-value of 10 for high thermal insulation. Designed for mountaineering, winter camping and extreme cold-weather backpacking, this mattress combines a durable air-core construction with insulating foam to reduce conductive heat loss to the ground and deliver a stable, comfortable sleeping surface in low temperatures.

Advantages

The mattress offers excellent thermal protection with an R-value of 10, significantly reducing heat loss to frozen or snow-covered ground. Its self-inflating design speeds up campsite setup and integrates insulating foam with an air chamber for a balance of comfort and warmth. The construction focuses on durability and shape stability, suitable for multi-season expedition use while remaining compact enough for carrying on extended trips.

Suitable for

• Winter camping and snow bivouacs where strong insulation is required
• High-altitude mountaineering and alpine expeditions
• Cold-weather backpacking and multi-season use
• Basecamp sleeping where prolonged night-time cold is expected

When it may not be suitable

This mattress is optimized for insulating performance in cold conditions; for warm-weather or summer-only trips its high insulation and bulk may be unnecessary. If ultralight, minimal-pack-volume gear is the priority for short fair-weather hikes, a lighter, less insulated pad could be a better choice.

Key specifications

• Type: Self-inflating mattress with integrated insulating foam and air core
• Thermal insulation: R-value 10 suitable for very cold conditions
• Intended use: Mountaineering, winter camping, cold-weather backpacking
• Comfort: Stable, cushioned sleeping surface designed for low-temperature use
• Durability: Robust construction for expedition and multi-season use

How to use

Unroll the EXPED Ultra 10R M on a flat, debris-free surface and open the valve to allow the integrated foam to self-inflate the mattress. Adjust firmness by adding or releasing air through the valve to achieve desired comfort and support. When packing, open the valve to compress and roll the mat tightly from the foot end to expel air, then close the valve for transport. Follow manufacturer guidance for storage to protect the insulating foam and valve.

What to consider before purchase

• Required insulation level for expected temperatures (R-value 10 is targeted at very cold conditions)
• Pack weight and volume relative to your carrying capacity and trip duration
• Compatibility with your sleeping bag and tent floor layout for full thermal performance
• Durability needs based on terrain and frequency of use

Usage recommendations

Use an additional groundsheet beneath the mattress to protect the surface from sharp objects and prolong its service life. For maximum thermal performance, place the mattress inside your tent and minimize gaps between the pad and sleeping bag; adjust inflation to balance comfort and insulation.
