The EXPED SIM Comfort 5 M is a self-inflating sleeping mat designed to combine moderate insulation with improved sleeping comfort. With a 5 cm foam core that self-expands when the valve is opened, the mat provides cushioning for car camping, trekking and basecamp situations. It weighs approximately 1.5 kg and rolls compactly for transport and storage; the valve design allows straightforward adjustment of firmness by adding or releasing air.
Advantages
The integrated foam core ensures reliable self-inflation and consistent thickness across the mat surface, reducing setup time compared with air-only pads. A 5 cm thickness balances comfort and pack size, offering a noticeable reduction of pressure points while remaining reasonably light for multi-day trips where vehicle access or short carries are involved. The simple valve system supports quick firmness adjustments and deflation for compact rolling and stowage.
Suitable for
- Car camping and weekend trips where weight is not the primary constraint
- Trekking and basecamp use with short carries between campsite and vehicle
- Campers who prefer a self-inflating foam core for faster setup
- Sleepers looking for moderate insulation and improved comfort over thin foam pads
When it may not be suitable
The EXPED SIM Comfort 5 M offers moderate insulation and is not intended for extreme cold conditions or high-altitude expeditions where a higher R-value or thicker insulation is required. For ultralight backpacking where every gram matters, the 1.5 kg weight and 5 cm thickness may be heavier and bulkier than dedicated ultralight inflatable pads.
Key specifications
- Comfort thickness: 5 cm foam core
- Approximate weight: 1.5 kg
- Construction: self-inflating foam core with outer fabric shell
- Valve: manual adjustment for inflation and deflation
- Packability: rolls compactly for transport and storage
How to use
Unroll the mat on a flat, clean surface and open the valve to allow the foam core to self-expand. Wait until the mat reaches the desired thickness, then close the valve. For a firmer sleeping surface, add a few breaths of air through the valve and then close it. To pack, open the valve and roll the mat tightly from the end opposite the valve to expel air, then close the valve briefly to maintain the rolled shape and secure with straps or the supplied stuff sack.
What to consider before purchase
- Intended use: car camping and basecamp versus ultralight backpacking
- Required insulation level for expected temperatures
- Pack size and how it fits your transport or storage constraints
- Preferred firmness and whether additional inflation or a pump will be used
Usage recommendations
Use a lightweight groundsheet or footprint under the mat to protect the fabric from abrasion and sharp objects. Regularly check and tighten valve fittings, and repair small punctures with a suitable patch kit to extend service life.
