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 crosswise foam channels, combined with the quiet upper material and a thickness of 5 cm, ensure peaceful nights. The XPEL multifunction valve allows for easy rolling up of the mat in the morning, and it fits neatly into the thoughtfully designed stuff sack without much twisting. You have the freedom to choose the shape: If you want to travel as lightweight as possible or tend to sleep quietly, you can opt for the mummy shape. For a larger sleeping area, Sea to Summit also offers the Pursuit SI Mat in a rectangular shape. In the regular size, this adds just 170 grams, giving you an extra 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.
