SEA TO SUMMIT Pursuit Plus SI Mat — self-inflating sleeping mat (insulated)

The SEA TO SUMMIT Pursuit Plus SI Mat is a self-inflating insulated sleeping mat engineered for camping and backpacking. Combining an open-cell foam core with a durable outer layer, this mat reduces heat loss to the ground and provides a consistent sleeping surface that balances cushioning and packability. Designed to roll compactly for transport and to inflate quickly on site, it is suitable for multi-night trips, car camping, and general outdoor overnight use where thermal protection and reliable comfort are required.

Advantages

The insulated construction increases thermal resistance to retain body heat and improve sleep comfort in cool conditions. Self-inflation simplifies setup: the core expands to draw air in and additional fine-tuning can be performed by a few breaths. The durable outer fabric resists abrasion and punctures typical of outdoor use. A low-profile thickness delivers a stable feel while keeping weight and packed volume reasonable for backpacking. The mat’s valve system enables controlled deflation and compact rolling for efficient packing.

Suitable for

• Backpacking multi-night trips where a balance of insulation and packability is needed
• Car camping and weekend trips with quick setup and reliable comfort
• Camping in cool weather where ground insulation reduces heat loss
• General outdoor use as a stable, insulated sleeping surface

Key specifications

• Self-inflating design with open-cell foam core for insulation
• Insulated construction for thermal protection from the ground
• Durable outer fabric for abrasion and puncture resistance
• Compact roll-up packed size for transport and storage
• Valve system for quick inflation control and efficient deflation

How to use

Lay the mat on a flat, clean surface and open the valve to allow the foam core to self-inflate. Wait until the core has expanded and the mat reaches near full thickness, then add a few breaths if needed to achieve desired firmness. Close the valve to retain pressure while sleeping. For packing, open the valve and roll the mat tightly from the end opposite the valve to expel air, then fasten with straps or the included cord and stow in its stuff sack.

Usage recommendations

Place a groundsheet or footprint beneath the mat on rough terrain to reduce abrasion and extend service life. Clean and air the mat after wet use and store it unrolled or loosely rolled in a dry place to preserve foam performance. Avoid sharp objects and excessive heat sources to prevent damage to the outer fabric and foam core.
