But its effectiveness depends on how you use it. It's the ideal plan B for those trekking or fastpacking in good conditions... but with their head in the right place.<\/p>\n\n\n\n<p>The basic assembly consists of stretching a rope between two trees and suspending the tubular blanket over it. It's as simple as that. The advantage of this design is that it provides insulation from both above and below - an important solution when cold or dampness comes from the ground.<\/p>\n\n\n\n<p>The structure can be completed by closing one end to protect it from wind or rain, using stones and ribbons if you don't want to complicate things.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Step-by-step assembly<\/strong>: <strong>Tubular Shelter<\/strong><\/h3>\n\n\n\n<p>The video shows two key configurations:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Land preparation<\/strong>The first thing to do is to prepare the area where you are going to sleep. Remove branches and stones. It is a basic step, but I assure you that you can spend a night \"to forget\" by skipping this step.<\/li>\n\n\n\n<li><strong>Insulate the ground<\/strong>Place dry sheets or a foam mat under your body (40% of the heat is lost by conduction with the ground).<\/li>\n\n\n\n<li><strong>Anchor between trees<\/strong>Use the rope to create a horizontal line between two logs, 1-1.5 m high. <\/li>\n\n\n\n<li><strong>Essential knots<\/strong>:\n<ul class=\"wp-block-list\">\n<li><strong>Prusik<\/strong>: To adjust the tension without slippage (locks under load, but slips when released).<\/li>\n\n\n\n<li><strong>Double lark<\/strong>To secure the ends of the rope (see the detail of the stone in the video).<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Open the blanket<\/strong>A: With stones or logs in the corners, create an \"A\" profile to maximise the space. You can also anchor these ends with pegs. <\/li>\n\n\n\n<li><strong>Close one end<\/strong>Use large stones wrapped in the blanket to block wind or rain from the side.<\/li>\n<\/ul>\n\n\n\n<p class=\"has-theme-palette-8-background-color has-background\"><strong><em>Point: <\/em><\/strong>You can go straight into the \"tube\", use it as an open tent or partially close it. And if you're like me (1.84m), be careful with space: not all these models are designed for long bodies, so choose the right product.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Mistakes you can make (and how to avoid them)<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Poor orientation<\/strong>If the wind enters from the open side, the shelter becomes a freezer.&nbsp;<strong>Solution<\/strong>Use natural elements that provide protection.<\/li>\n\n\n\n<li><strong>Insufficient insulation<\/strong>If you don't have a mat, you can spend the night shivering.&nbsp;<strong>Council<\/strong>Even a layer of leaves under the blanket helps.<\/li>\n\n\n\n<li><strong>Environmental footprint<\/strong>Avoid damaging the vegetation when preparing the soil. It is one thing to remove stones and branches and another to prepare the soil as if you were using a rotavator. <\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>What scenarios is it really for?<\/strong> Is it useful or just posturing?<\/h3>\n\n\n\n<p>For me, this is not just a \"survival trick\". It's a real, practical solution for one to three day routes in predictable conditions. It's not a substitute for a tent if you're going to exposed areas or in bad weather, but it can get you out of trouble if you wanted to sleep out in the open and suddenly the weather changes.<\/p>\n\n\n\n<p>And above all, I like what it hints at: it's not just about the equipment we carry, but how we use it. With knowledge and a little imagination, 240g can make a difference.<\/p>\n\n\n\n<p class=\"has-theme-palette-7-background-color has-background\"><em><strong>Technical data<\/strong>: <\/em>A thermal blanket reflects up to 90% of body heat, but its effectiveness drops if there is direct contact with the body (so air space in tent mode is key).<\/p>\n\n\n\n<p>In short: this system does not replace a tent in winter, but it is ideal for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Emergencies<\/strong>: Sudden storms or lost luggage.<\/li>\n\n\n\n<li><strong><em>Fastpacking<\/em> in summer<\/strong>Routes of 2-3 days with a stable forecast.<\/li>\n\n\n\n<li><strong>Secondary shelter<\/strong>As a complement to a light sleeping bag.<\/li>\n<\/ul>\n\n\n\n<p><\/p>","protected":false},"excerpt":{"rendered":"Imagine this: you are on a three-day route, the sky suddenly darkens,...","protected":false},"author":191,"featured_media":48342,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_kad_blocks_custom_css":"","_kad_blocks_head_custom_js":"","_kad_blocks_body_custom_js":"","_kad_blocks_footer_custom_js":"","episode_type":"audio","audio_file":"","cover_image":"","cover_image_id":"","duration":"","filesize":"","date_recorded":"","explicit":"","block":"","filesize_raw":"","_kadence_starter_templates_imported_post":false,"_kad_post_transparent":"","_kad_post_title":"","_kad_post_layout":"","_kad_post_sidebar_id":"","_kad_post_content_style":"","_kad_post_vertical_padding":"","_kad_post_feature":"hide","_kad_post_feature_position":"","_kad_post_header":false,"_kad_post_footer":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[2946],"tags":[],"series":[],"class_list":["post-48335","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-montana"],"episode_featured_image":"https:\/\/travesiapirenaica.com\/wp-content\/uploads\/2025\/05\/refugio-ultraligero-manta-termica-trekking-supervivencia.webp","episode_player_image":"https:\/\/travesiapirenaica.com\/wp-content\/uploads\/2017\/12\/Caratula-Podcast-Maldita-Montana_1500x1500_72pp-p_.jpg","download_link":"","player_link":"","audio_player":false,"episode_data":{"playerMode":"dark","subscribeUrls":[],"rssFeedUrl":"https:\/\/travesiapirenaica.com\/en\/feed\/podcast\/maldita-montana","embedCode":"<blockquote class=\"wp-embedded-content\" data-secret=\"C8Y5OOemZd\"><a href=\"https:\/\/travesiapirenaica.com\/en\/ultralight-shelter-thermal-blanket-trekking-survival-blanket\/\">El refugio ultraligero que cabe en tu bolsillo (y puede sacarte de un apuro)<\/a><\/blockquote><iframe sandbox=\"allow-scripts\" security=\"restricted\" src=\"https:\/\/travesiapirenaica.com\/en\/ultralight-shelter-thermal-blanket-trekking-survival-blanket\/embed\/#?secret=C8Y5OOemZd\" width=\"500\" height=\"350\" title=\"&#8220;El refugio ultraligero que cabe en tu bolsillo (y puede sacarte de un apuro)&#8221; &#8212; Traves\u00eda.\" data-secret=\"C8Y5OOemZd\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\" class=\"wp-embedded-content\"><\/iframe><script>\n\/*!
