Light packing, good sleeping, and starting fresh the next day: With the self-inflating Pursuit SI Mat from Sea to Summit, you get the complete package for weight-optimized travel. The cross-running foam channels, combined with the rustle-free top material and a thickness of 5 cm, ensure peaceful nights. The XPEL multifunctional valve allows for easy rolling up of the mat in the morning, and it fits neatly into the thoughtfully designed stuff sack without much hassle. You have the freedom to choose the shape: if you want to travel as lightly as possible or tend to sleep more soundly, you can opt for the mummy shape. For an expanded sleeping area, Sea to Summit also offers the Pursuit SI Mat in a rectangular shape. In the regular size, this only adds an extra 170 grams, but you gain 8 cm in length across the entire sleeping surface. The sleeping mat has an R-value of 3.0, making it suitable for use from spring to autumn.
