Rab Ultrasphere 1.5 Sleep Mat

The ultralight inflatable Rab Ultrasphere 1.5 (Long Wide) is built for fast-and-light backpacking, bikepacking and multi-day summer trips where weight and packed size matter. It provides modest insulation and improved sleeping comfort for warmer nights.

Key benefits

• Offset air-chamber construction: traps warmth closer to the body while keeping weight low.
• Soft 20D fabric: very light with reasonable abrasion resistance.
• Mummy taper (Long Wide): extra length and width for more room without much extra bulk.
• Two-way valve and inflation sack: quick to inflate and easy to fine-tune firmness.
• Included roll‑away sack and repair kit: practical for field repairs and compact storage.

Typical use: summer and shoulder-season trekking, bikepacking and mountain running trips where minimising weight and packed volume is the priority, and only modest insulation (R≈1.4) is needed for milder nights.
