It keeps the brand\u2019s minimalist philosophy and is very similar to the Southwest, but with more accessible external pockets, designed for long hikes without needing to stop.<\/p>\n<p><iframe src=\"https:\/\/www.youtube.com\/embed\/8YNyQOeZ5B0\" width=\"640\" height=\"360\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n<hr \/>\n<h2>When to use it<\/h2>\n<p>The Unbound 55 is perfect for multi-day routes where you need more capacity without giving up light weight. With a total volume of 55 liters (44 liters inside + 11 liters in pockets), it lets you carry a bit more gear for long treks or when you need more self-sufficiency.<\/p>\n<p>It is fully waterproof thanks to the Dyneema fabric and taped seams, so there\u2019s no need to carry a pack cover. It can also carry up to 18 kg comfortably.<\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-16664\" src=\"https:\/\/superligero.es\/wp-content\/uploads\/2024\/04\/Mochila-para-senderismo-334.jpg\" alt=\"Hiking backpack\" 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 your gear while on the move. The roll-top lets you adjust the volume depending on what you\u2019re carrying, and the bottom pocket is ideal for storing items you want to keep within reach at all times.<\/p>\n<p>As in the 40L model, it includes a removable stay that transfers weight to the hipbelt without the need for a full frame, keeping weight low and improving comfort on the trail.<\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-16667\" src=\"https:\/\/superligero.es\/wp-content\/uploads\/2024\/04\/Mochila-para-senderismo-445.jpg\" alt=\"Hiking backpack\" width=\"640\" height=\"427\" \/><\/p>\n<div class=\"texto-instagram\">Photo @<a href=\"https:\/\/www.instagram.com\/ztracenvlese\/\" target=\"_blank\" rel=\"noopener\">ztracenvlese<\/a> and <a href=\"https:\/\/www.instagram.com\/petra_detska\/\" target=\"_blank\" rel=\"noopener\">petra_detska<\/a><\/div>\n<hr \/>\n<h2>Made from Dyneema Composite Hybrid<\/h2>\n<p>It\u2019s made from Dyneema Composite Hybrid (DCH) fabric, which combines Dyneema and polyester.
