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.
Amazing speed and excellent service. Everything I have bought has arrived in less than expected time. This site is a lifesaver when living in Australia.
Why didn’t I buy one sooner!!!
Awesome product. Awesome service!
Extra comfort and no fogging.
I’m not going to comment on the product I bought but the service received
WOW! Super fast delivery VERY happy customer
I bought a knock off elsewhere to compare this to (for just $5), and the difference is night and day. Unlike the knock off, this actually cuts well (especially the scissors, which are amazing on this compared to the useless ones on the knock off that can't cut anything due to a bad pin hinge) and actually retains its edge (because it uses good steel, unlike the fake). It's a tad pricy for its size, but you get the quality that you pay for.
