． Ultrasphere 4.5 combines TILT heat-reflective and heat-blocking air chamber structures to provide excellent warmth and comfort despite being lightweight and highly compressed, making it an ideal choice for multi-day hiking and trail running.
． The outer fabric is made of 20D recycled polyester, the interior is TPU coated, and the environment-friendly fluorocarbon-free water-repellent treatment.
． The inside of the air chamber is made of 2 layers of TILT metal reflective film, which further reduces radiant heat loss without increasing weight and volume.
． The interior of the air chamber uses an offset compartment structure that reduces weight while helping to reduce air flow and retain more warm air.
． The flat and thin inflation valve has a two-way design that can inflate and deflate at the same time.
． An inflatable bag is included, which is fast and hygienic.
． Comes with a repair kit that can be used immediately after patch repair.
