Ionosphere 5 Sleep Pad

• Product Details

  What Our Gearhead Experts Are Saying:

  "I trusted the Ionosphere 5 Sleep Pad on a high-altitude mountaineering trip with overnight temps well below freezing and woke up warm and rested every single morning. The mummy shape cuts weight without sacrificing the coverage that actually matters, and the pump sack inflation is genuinely fast at the end of a long day."

  Cold ground is one of the most reliable ways to ruin a night in the backcountry, and the Rab Ionosphere 5 Sleep Pad exists to solve that problem without making you carry a heavier kit to do it. With an R-value of 4.8 and a construction built specifically around reducing heat loss through both radiation and convection, this pad pulls serious warmth-to-weight duty on everything from ambitious alpine objectives to deep wilderness nights far from the trailhead.

  The 20D recycled polyester face fabric wears a TPU coating and FC-free DWR treatment for durability and moisture resistance, while 160g of Stratus R recycled polyester insulation works alongside a TILT reflective film to trap and redirect body heat back where it belongs. The mummy shape keeps the overall footprint trimmed without sacrificing coverage where it matters most, and the included pump sack makes inflation fast and effortless at the end of a long day. At just over a pound for the regular size and packing down to under ten inches, the Ionosphere 5 Sleep Pad earns its place in any ultralight kit without asking for much space in return.
