Tianshan Ultra is the material-upgraded version of Tianshan, manufactured using Ultra200x – the most durable fabric we can provide. This material is woven with a high content of Ultra High Molecular Weight Polyethylene (UHMWPE) and laminated with PE film to form a composite layered fabric. Combined with UltraTNT tape, it creates backpacks with high waterproof performance. Ultra200x is one of the strongest fabrics in the world.

Since Ultra200x does not use DWR, it contains no PFAS.

While 90% seams are sealed with waterproof tape (minimizing leakage risk during hiking), submersion in water may compromise protection. For extended wet conditions, we recommend using an internal liner (e.g., heavy-duty plastic bag) as secondary waterproofing for critical insulating gear such as sleeping bags and down jackets.

We optimized the RAS back system of the Yue45 to simplify its complex frame. Additionally, we incorporated a curved back panel that’s highly ventilated, making it perfect for hot weather.

The backpack features the classic Qidian Pro design because, well, we all love it.

It weighs under 1kg but can handle up to 15kg of gear.
