Sleeping Pad EXPED Ultra 3R M Mummy self-inflating mattress — lime, model 697374

EXPED Ultra 3R M Mummy self-inflating mattress — lime, model 697374 is a lightweight, mummy-shaped sleeping pad designed for backpacking and camping. The self-inflating foam core expands when unrolled, providing a combination of insulation and cushioning that reduces heat loss to the ground and improves sleeping comfort. The narrow mummy profile focuses padding under the torso and hips while minimizing packed size and weight for multi-day trips.

Advantages

The sleeping pad combines low weight and compact packed dimensions with a self-inflating foam construction that speeds setup and offers consistent core support. The mummy shape reduces bulk and increases thermal performance by concentrating insulation where it is needed most. Durable outer materials and an integrated valve simplify inflation, adjustment and deflation for storage. The lime color increases visibility in camp and helps distinguish the pad from other gear.

Suitable for

• Backpacking trips where low weight and compact size are priorities
• Three-season camping and overnight stays in established campsites
• Solo hikers and campers who prefer a mummy-shaped insulating pad
• Fastpacking or multi-day routes requiring quick setup and teardown

When it may not be suitable

The mummy profile and narrower width may feel restrictive for side sleepers who prefer a wider sleeping surface. This pad is designed primarily for three-season use; in very cold winter conditions or on glaciers additional insulation or a winter-specific pad may be required to achieve adequate thermal protection. Users seeking luxury-level cushioning may find thicker, high-R-value mats more comfortable.

Key specifications

• Type: Self-inflating sleeping pad with closed-cell foam core
• Shape: Mummy profile optimized for single-sleeper insulation
• Intended use: Backpacking and camping for one person
• Construction: Foam-supported air chambers for combined insulation and cushioning
• Weight class: Lightweight, designed for compact packing and carrying
• Colour: Lime

How to use

Unroll the pad on a relatively flat, debris-free area inside your tent or on the ground. Open the valve to allow the foam core to self-expand; wait until the pad reaches its normal thickness, then close the valve. For firmer comfort or to increase insulation, add a few breaths of air through the valve and then close it. To pack, open the valve, roll the pad tightly from the opposite end toward the valve to expel air, then close the valve and secure the rolled pad in its storage sack.

What to consider before purchase

• Preferred sleeping position and whether a narrower mummy shape is comfortable
• Seasonal use and required insulation level for expected temperatures
• Acceptable trade-off between weight/packed size and cushioning thickness
• Compatibility with existing sleeping bag dimensions and tent floor space

Usage recommendations

Use a groundsheet or footprint under the pad to protect the fabric from abrasion and sharp objects. Regularly check and maintain the valve and seams, and repair punctures promptly with an appropriate patch kit. Store the pad loosely rolled or unrolled in a dry place to preserve foam performance.
