It's not quite the Ultralight, but there's the ULS (Ultra Lightweight Structure) for that. The ULS caters to those who seek equipment specialized for ultra-lightweight needs. Now, let's focus on the new Lightpack DLS. Coming in 81-liter and 91-liter sizes, weighing between 620 and 650 grams, it's designed for comfort and versatility. The ergonomic, adjustable shoulder straps provide a tailored fit, and the adjustable top shoulder straps enhance stability, easily adaptable to my needs. The chest strap, featuring high-quality nylon buckles, ensures a secure fit. It's adjustable, allowing movement to different positions. A nifty label slot, conveniently accessed from the top, catches my attention. There's even a built-in helmet cover cleverly disguised as a hair net. Putting the backpack on my back, I fine-tune the waist strap tension to ensure it rests perfectly on my hips. Securing the chest strap holds the shoulder straps in place, just right. Interestingly, there are no compression straps on the sides, as the bag is designed to accommodate gear without excess space. The backpack's elasticated waist strap boasts pockets on both sides, handy for storage. The presence of a zip pocket and a stretchy pocket adds to the pack's practicality. Additionally, elasticated loops for a hydration tube and a grab handle on top complete the thoughtful design. Comparing the Lightpack DLS to the ULS, the former lacks some features. There are no extra-wide shoulder straps with built-in pockets, no triangulated extra supports at the base, and no fast strip on the left shoulder strap. The ULS is optimized for running stability. In conclusion, the Advance Lightpack DLS offers durability and comfort. Its thoughtful design and versatile features make it a reliable companion for various outdoor activities, catering to a slightly heavier load than the ULS." - Carlo Borsattino, Flybubble Watch the Flybubble full video review: FAQ What differences are there between the LIGHTPACK DLS and LIGHTPACK ULS?
