Inflatable Mattress EXPED Ultra 3R M – self-inflating camping pad, model Ultra 3R M

The EXPED Ultra 3R M – self-inflating camping pad is an inflatable mattress engineered to provide insulated sleeping support for backpacking, trekking and touring. It combines a lightweight construction with a compact pack profile and simple self-inflation for quick setup at campsites. The mattress offers a balance of cushioning and thermal insulation to improve overnight comfort on uneven or cold ground while keeping carry weight low for multi-day trips.

Advantages

The Ultra 3R M uses lightweight materials and an efficient internal structure to deliver stable support with reduced bulk. Self-inflation shortens setup time and decreases reliance on external pumps, while the insulated core helps retain body heat during cooler nights. The compact packed size and low weight make it suitable for rucksack transport, and the inflatable design allows for adjustable firmness by adding or releasing air.

Suitable for

• Backpacking and multi-day trekking where weight and pack size matter
• Camping and touring trips that require insulated sleeping pads
• Lightweight car-camping when space-efficient gear is preferred
• Use on uneven terrain when additional cushioning and thermal protection are needed

When it may not be suitable

This self-inflating pad may not be the best choice for users who need an ultrathick mattress for sofa-like comfort or for those who prefer foam-only pads that never puncture. It is also less suitable where maximum durability against sharp rocks or heavy repeated abrasion is required without an extra protective layer or groundsheet.

Key specifications

• Type: inflatable, self-inflating camping pad
• Intended use: insulated sleeping support for backpacking, trekking and touring
• Construction: lightweight materials with compact pack profile
• Inflation: self-inflating with manual air adjustment
• Portability: designed for rucksack transport with reduced carry weight

How to use

Unroll the mattress on a clean, flat surface and open the valve to allow it to self-inflate. Wait for the pad to expand, then add a few breaths of air through the valve to achieve the desired firmness. Close the valve when the firmness is set. To pack, open the valve, roll the mattress tightly from the foot end toward the valve to expel air, then close the valve and secure the rolled pad in its storage sack or strap it to your pack. For long-term storage leave the valve slightly open to maintain foam resilience.

What to consider before purchase

• Required R-value or insulation level relative to expected night temperatures
• Desired balance of weight versus cushioning and packed size
• Compatibility with your sleeping bag dimensions and tent floor space
• Need for an additional groundsheet or patch kit for rocky campsites

Usage recommendations

Use a groundsheet or footprint under the mattress to reduce abrasion and puncture risk. Adjust firmness each night to suit sleeping style and temperature. Carry a repair kit for quick on-trail patching, and rinse off dirt and allow the pad to dry before storing to prolong material life.
