Sleeping mat SEA TO SUMMIT UltraLight Mat 550 × 1840 mm, 5 cm thickness, 395 g, nylon/TPU, self‑inflating, waterproof, yellow

The Sea To Summit UltraLight Mat 550 mm x 1840 mm in Yellow is a compact, single-person sleeping mat designed for backpacking and outdoor use. Constructed from nylon with extrusion-laminated thermoplastic polyurethane (TPU), the mattress provides a 50 mm (5 cm) sleeping surface thickness and a balance of low pack weight with overnight comfort. The integrated Airstream Pump is built into the stuff sack for quick inflation without needing an external pump.

Advantages

The Air Sprung Cells conform to body shape to distribute pressure evenly across the mat, improving sleep comfort compared with conventional mats. Extrusion TPU lamination reduces the risk of delamination compared with roll-to-roll methods, increasing durability. A multi-function valve enables fast inflation, rapid deflation and fine-tuning of firmness for personalised comfort. The ultra-light construction uses a single layer of medium-resolution cells to keep weight and packed volume minimal while maintaining adequate cushioning.

Suitable for

• Backpacking and minimalist overnight trips
• Solo campers who prioritise low weight and compact size
• Hiking trips where quick setup and packability are required

Usage recommendations

For best results on multi-night trips, check valve tightness before sleep, inflate to a firmness that supports your hips and shoulders, and carry a repair kit suitable for TPU/nylon airbeds in case of punctures.
