This is precisely where the Sirrus 36 excels. The adjustable fit, specifically developed for the female anatomy, combined with the highly ventilated AirSpeed\u2122 system, guarantees a cool and comfortable feel even on hot days or intense climbs.<\/p>\n<h4>Everything has its place<\/h4>\n<p>The spacious main compartment with top access (toploader) and drawstring closure allows quick access to your gear. The lower zipped access leads directly to the separate compartment - perfect for sleeping bags or extra clothes. The large front pocket with vertical zip, two zip pockets on the lumbar belt and elasticated side pockets make it easy to organise your essentials.<\/p>\n<p>Practical details such as the Stow-on-the-Go\u2122 system for quick attachment of trekking poles, piolet holder, compression straps and front attachment points make this backpack versatile - from summer trails to more technical routes.<\/p>\n<h4>AirSpeed\u2122 Back System<\/h4>\n<p>The LightWire peripheral frame offers stability and excellent load transfer. The tensioned mesh back panel creates a space between the back and the body of the rucksack, allowing continuous air circulation. The result: less heat build-up and greater comfort on long stages.<\/p>\n<h4>Straps and Lumbar Belt<\/h4>\n<p>The padded, edgeless shoulder straps with breathable Spacermesh distribute the weight evenly. Perforated ventilation channels further increase breathability. The adjustable chest strap includes magnetic closure, emergency whistle and magnetic attachment for hydration valve.<\/p>\n<p>The ErgoPull\u2122 system on the lumbar belt adapts to the body and ensures a stable and comfortable load transfer to the hip - essential when the rucksack is fully loaded.<\/p>\n<h4>Mackintosh included<\/h4>\n<p>The waterproof rain cover is stored in the lower compartment and is ready to use in seconds - guaranteed protection when the weather suddenly changes.<\/p>\n<h4>Sustainability<\/h4>\n<p>As a bluesign\u00ae PRODUCT, Sirrus 36 fulfils strict environmental and social criteria. It is made from recycled and bluesign\u00ae certified nylon 100 %, with PFAS-free DWR treatment.<\/p>\n<h2>Osprey Sirrus 36 highlights<\/h2>\n<p>\ud83c\udf92 36 litres ideal for day hikes or weekends<\/p>\n<p>\ud83c\udf2c\ufe0f AirSpeed\u2122 system with maximum ventilation<\/p>\n<p>\ud83c\udf27\ufe0f Integrated rain cover in the lower compartment<\/p>\n<p>\ud83e\udd7e Stow-on-the-Go\u2122 quick fix for poles<\/p>\n<p>\ud83e\udded Separate lower compartment with zip<\/p>\n<p>\ud83d\udcf1 Two zip pockets on the lumbar belt<\/p>\n<p>\ud83e\uddf5 Recycled and bluesign\u00ae certified materials<\/p>\n<h3>Osprey Sirrus 36 Technical Details<\/h3>\n<p>\ud83d\udccf Dimensions: 65 x 34 x 33 cm<\/p>\n<p>\u2696\ufe0f Weight: 1.49kg<\/p>\n<p>Capacity: 36 litres<\/p>\n<p>Main material: recycled nylon 100 % (100D x 210D Honeycomb Ripstop), DWR without PFAS<\/p>\n<p>Reinforcements: recycled nylon 100 % (210D), DWR without PFAS<\/p>\n<p>\ud83d\udee1\ufe0f Base: recycled nylon 100 % (420D), DWR without PFAS<\/p>\n<p>\ud83c\udf0d Certification: bluesign\u00ae PRODUCT<\/p>","protected":false},"excerpt":{"rendered":"<p>A <strong>Osprey Sirrus 36<\/strong> is a women's hiking backpack with 36 litres of capacity, exceptional ventilation and maximum carrying comfort.
