Advance LIGHTPACK ULS details

Flybubble review

The Lightpack ULS is part of the comprehensive WEIGHTLESS scope of delivery. This mini review is part of Advance Weightless first impression video review:

“All my gear (Advance Weightless, Phi Sola, helmet...) is fitting in there really easily, I can fit my open helmet inside. I really like, the shoulder straps are a bit different. Yeah, you can see they've got this kind of pad too. It has lots of pockets and other nice details. Instead of having a normal support, to stop the ruck moving across, they've done something interesting where they've put the rucksack going acros to make triangle shape. Very lovely, like it a lot. I'm keeping it.”

Carlo Borsattino, Flybubble

Carlo reviewed Lightpack DLSas well and he frequently mentioned ULS model as well.

"The Advanced Lightpack DLS holds a promise of durability and lightweight construction. 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.

The ULS variant is all about catering to the ultra-lightweight enthusiasts, those who prioritize streamlined gear and specialized equipment. The ULS is finely tuned for individuals who might be engaged in activities like running with their equipment, where stability and compactness are paramount.

The ULS packs in some distinct features that set it apart from its sibling, the Lightpack DLS. For starters, it boasts extra-wide shoulder straps with built-in pockets – a clear nod to practicality and easy access. Notably, there are triangulated extra supports at the bottom, offering enhanced stability during dynamic movements.

And let's not forget the fast strip on the left shoulder strap – a small yet ingenious addition designed to optimize convenience during active pursuits. All these elements are thoughtfully engineered to accommodate the needs of those who demand a compact, stable, and lightweight pack while on the move.

In essence, the ULS caters to a specific niche of adventurers, those who prefer to run and maintain a streamlined profile while carrying their gear. It's an embodiment of Advance's commitment to catering to various preferences within the outdoor community.

In conclusion, the Advanced 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."
