With a total capacity of 48L and a weight starting at 1,063 g, it&#8217;s designed for 3 to 5-night trips when you have fine-tuned your gear and don&#8217;t want to carry extra volume.<\/p>\n<p>Its suspension system with an internal hoop transfers the load between shoulders and hips without becoming rigid, offering a balance that is hard to find: structure and comfort for many days of hiking without adding weight. Recommended for loads under 35 lb (15.9 kg).<\/p>\n<p><iframe loading=\"lazy\" src=\"https:\/\/player.vimeo.com\/video\/1033611239?h=da24bfd2e8\" width=\"640\" height=\"360\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n<hr \/>\n<h2>When to Use It<\/h2>\n<p>Ideal for multi-day treks, fast hikes, or ultralight backpacking where you seek a pack with structure but with limited volume. The Circuit SV shines when your system is already compact: quilt or lightweight sleeping bag, ultralight tent, and food for several days without having to &#8220;fill&#8221; empty liters.<\/p>\n<p>It is a good choice if you want a pack capable of carrying the load stably (up to 15.9 kg recommended), but you don&#8217;t need the 68L of a larger volume backpack. It&#8217;s also suitable for routes where you need to organize gear by pockets (front mesh, sides, and waist) and access water or snacks on the go.<\/p>\n<hr \/>\n<h2>Design<\/h2>\n<p>The Circuit SV maintains ULA&#8217;s typical functional focus: roll-top closure like a dry bag, side compression, contoured shoulder straps, and load lifters to adjust the load. You can choose between J-Strap or S-Strap shoulder straps depending on your anatomy and fit preference.<\/p>\n<p>Includes a padded back system and an interchangeable hip-belt with large pockets. Additionally, it features loops for ice axes and trekking poles, a front shock cord, and the option to add strap kits (Top Y-strap \/ Bottom strap) for carrying sleeping pads or bulky gear.<\/p>\n<p>Regarding actual capacity, ULA states the total volume including external pockets. The Circuit SV can fit a BearVault BV500 vertically inside the main compartment, useful for routes that require a canister.<\/p>\n<hr \/>\n<h2>Technical Fabrics<\/h2>\n<p>In its Robic version, it uses ULA 400 Robic: a Robic nylon with high tear and abrasion resistance, reinforced with ripstop and DWR treatment without PFAS (C0) and PU coating for improved water resistance.<\/p>\n<p>The front pocket uses UltraStretch\u2122 Mesh, a 4-way stretch mesh designed to last and better withstand wear than typical meshes, providing quick access to layers, filters, maps, or trash.<\/p>\n<hr \/>\n<h2>Specifications<\/h2>\n<ul>\n<li class=\"p1\">Total capacity: 48 L (2,929 cu in)<\/li>\n<li class=\"p1\">Volume breakdown: main body with extension 37 L \/ front pocket 3.5 L \/ side pockets 2 L + 2 L \/ hipbelt pockets 1.5 L + 1.5 L<\/li>\n<li class=\"p1\">Weight (at a glance): 1,063 g (37.5 oz)<\/li>\n<li class=\"p1\">Maximum recommended load: 15.9 kg (35 lb)<\/li>\n<li class=\"p1\">System: framed backpack + internal suspension hoop<\/li>\n<li class=\"p1\">Closure: roll-top<\/li>\n<li class=\"p1\">Adjustable fit: torso adjustable (sizes Small 15&#8243;\u201318&#8243; \/ Medium 18&#8243;\u201321&#8243; \/ Large 21&#8243;\u201324&#8243;)<\/li>\n<li class=\"p1\">Interchangeable hip-belt: XS 26&#8243;\u201330&#8243; \/ S 30&#8243;\u201334&#8243; \/ M 34&#8243;\u201338&#8243; \/ L 38&#8243;\u201342&#8243; \/ XL 42&#8243;\u201347&#8243; \/ XXL 47&#8243;+<\/li>\n<li class=\"p1\">Shoulder straps: J-Strap or S-Strap (optional)<\/li>\n<li class=\"p1\">Details: large hipbelt pockets, side compression, loops for ice axes\/trekking poles, front shock cord<\/li>\n<li class=\"p1\">Compatibility: BearVault BV500 upright<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>This is a Superligero ultralight hiking backpack of 48L designed for multi-day routes with a moderate load.
