Their project aims to raise public awareness about the environmental challenges of polar regions while collecting crucial data on the effects of climate change. To ensure their safety and effective communication in extreme weather conditions, SENA, the global leader in intercom systems, is equipping them with the Latitude S1 helmet and the Snowtalk 2 intercom. These devices allow He\u00efdi and Matthieu to stay connected at all times, even in the worst fog or storm conditions. He\u00efdi emphasizes the importance of this connection: &#8220;We communicate a lot throughout the day thanks to our connected Sena ski helmets. We keep each other updated on the weather, snow conditions, and it even allows us to listen to music to stay motivated.&#8221;<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-5 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"768\" height=\"1024\" data-id=\"40470\" src=\"https:\/\/www.sena.com\/wp-content\/uploads\/2024\/07\/Matthieu_img3-768x1024.jpg\" alt=\"\" class=\"wp-image-40470\" srcset=\"https:\/\/www.sena.com\/wp-content\/uploads\/2024\/07\/Matthieu_img3-768x1024.jpg 768w, https:\/\/www.sena.com\/wp-content\/uploads\/2024\/07\/Matthieu_img3-225x300.jpg 225w, https:\/\/www.sena.com\/wp-content\/uploads\/2024\/07\/Matthieu_img3.jpg 800w\" sizes=\"(max-width: 768px) 100vw, 768px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"768\" height=\"1024\" data-id=\"40454\" src=\"https:\/\/www.sena.com\/wp-content\/uploads\/2024\/07\/Matthieu_img2-768x1024.jpg\" alt=\"\" class=\"wp-image-40454\" srcset=\"https:\/\/www.sena.com\/wp-content\/uploads\/2024\/07\/Matthieu_img2-768x1024.jpg 768w, https:\/\/www.sena.com\/wp-content\/uploads\/2024\/07\/Matthieu_img2-225x300.jpg 225w, https:\/\/www.sena.com\/wp-content\/uploads\/2024\/07\/Matthieu_img2.jpg 800w\" sizes=\"(max-width: 768px) 100vw, 768px\" \/><\/figure>\n<\/figure>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-the-importance-of-field-testing-according-to-sena\">The Importance of Field Testing According to SENA<\/h3>\n\n\n\n<p>For SENA, field testing is crucial to ensuring product performance and reliability. &#8220;It is vital for us to see our equipment in action under the most extreme conditions,&#8221; explains a SENA representative. He\u00efdi and Matthieu&#8217;s expeditions provide the perfect opportunity for this. The Latitude S1 helmets and Snowtalk 2 intercoms, specifically designed for polar environments, enable clear communication even in strong winds, offer long-range connectivity, and withstand harsh weather. He\u00efdi particularly appreciates these features: &#8220;The helmets not only keep us in constant contact but also allow us to listen to music during long kite sessions. This can really make a difference in maintaining morale and energy, especially when our legs are tired at the end of the day.&#8221; Through field feedback from He\u00efdi and Matthieu, SENA can continuously improve its products to meet the needs of adventurers and scientists, ensuring their safety and comfort.<\/p>\n","protected":false},"featured_media":40520,"template":"","acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.3 (Yoast SEO v22.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>He\u00efdi Sevestre &amp; Matthieu Tordeur - SENA<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.sena.com\/en-eu\/stories\/people\/heidi-sevestre-matthieu-tordeur\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"He\u00efdi Sevestre &amp; Matthieu Tordeur\" \/>\n<meta property=\"og:description\" content=\"Introduction to He\u00efdi and Matthieu He\u00efdi Sevestre and Matthieu Tordeur are two iconic figures in polar exploration and scientific research.
