Inside the Ultrasphere 4.5 is two layers of Rab's TILT reflective film which reduces radiant heat loss without adding weight or bulk and does not rustle at all like other heat reflective insulation technologies. Using just TILT layers to create reflectiv insulation results in an absolutely tiny pack size and impressive warmth with an R-Value of 4.3.
The Ultrasphere 4.5 is constructed from lightweight 20D Recycled Polyester with internal TPU Coating and fluorocarbon free DWR that will ensure that the mat dries quickly should any rain get in through your tent. The 2 way inflate / deflate valve means that the mat can be quickly inflated using the included pump sack, then when it's time to move on can be quickly deflated.
