It maintains the brand&#8217;s minimalist philosophy and is very similar to the Southwest, but with more accessible exterior pockets, designed for long hikes without the need to stop.<\/p>\n<p><iframe loading=\"lazy\" title=\"vimeo-player\" src=\"https:\/\/player.vimeo.com\/video\/782967423\/\" width=\"640\" height=\"360\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n<hr \/>\n<h2>When to Use<\/h2>\n<p>The Unbound 55 is perfect for multi-day routes where you need more capacity without sacrificing lightness. With a total volume of 55 liters (44 liters interior + 11 liters in pockets), it allows you to carry a bit more gear for long treks or if you need more autonomy.<\/p>\n<p>It is completely waterproof thanks to the Dyneema fabric and its sealed seams, so there is no need to carry a rain cover. Additionally, it can comfortably carry up to 18 kg.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-16664\" src=\"https:\/\/superligero.es\/wp-content\/uploads\/2024\/04\/Mochila-para-senderismo-334.jpg\" alt=\"Backpack for hiking\" width=\"640\" height=\"427\" \/><\/p>\n<div class=\"texto-instagram\">Photo @<a href=\"https:\/\/www.instagram.com\/hyperlite_mountain_gear\/\" target=\"_blank\" rel=\"noopener\">hyperlite_mountain_gear<\/a><\/div>\n<hr \/>\n<h2>Design<\/h2>\n<p>The side and front pockets are designed for easy access to gear while on the move.
