3F UL GEAR ULTRA200x Strong and Large 15kg Weight Hiking Thick Shoulder Hiking Rucksack Waist Belt Backpack, Fabric, PU140000mm, Ultra-Lightweight

[ULTRA and Dyneema] The ULTRA Collection is a revolutionary material developed by Challenge Outdoor, USA, in 2019 and released in 2021. Like Dyneema, it uses UHMWPE (ultra-high molecular weight polyethylene) fiber, which boasts the world's highest specific strength and specific modulus, said to be 15 times stronger than steel. According to Challenge Outdoor's testing results, ULTRA material's tear resistance is approximately three times that of Dyneema, and its abrasion resistance is more than seven times greater, demonstrating its incredible performance. [ULTRA 200x] 3F UL GEAR's newly developed mountaineering backpack, the ULTRA200x, is an updated version of the ULTRA200, released in 2023. New special technology further strengthens rigidity and improves stability. Compared to Dyneema, it offers significant improvements in three core performance areas: tear strength, UHMWPE fiber content, and abrasion resistance, without significantly changing weight. It also boasts a waterproof rating of 200 psi (equivalent to PU140613mm), providing exceptional performance in a wide range of harsh conditions, from extreme cold to tropical climates. (*It is not completely waterproof, so we recommend using it with a waterproof bag.) [Built-in Frame, Reduces Burden] The curved aluminum frame prevents the hiking sack from clinging tightly to your back and waist. This ensures breathability and makes carrying it comfortable, especially in the hot summer. To reduce shoulder pressure when carrying the sack, the back is equipped with adjustable back straps and a waist belt. This reduces fatigue even during long periods of use and ensures a comfortable fit. The waist belt is secured to the frame, so you can remove it by removing the lower part of the frame. Lightweight and Large Capacity: The 3F UL GEAR lightweight backpack weighs approximately 950g, or less than 1kg. Its low weight and ability to withstand a certain load make it ideal for short trips and camping trips. It's perfect for short trips with light luggage or week-long trips. Additionally, the top of the hiking backpack has an expandable space of approximately 10L, allowing you to increase capacity as needed or roll it up for compact storage. Its single-compartment design makes it easy to store large items. (Recommended load capacity: up to 15kg) [Storage Capability] The backpack features three adjustable back straps to accommodate users of different body types. It also features a water bottle pocket, side pockets, and a storage pocket on the waist belt. Mesh pouches on the front and back provide excellent storage. The mesh pouch on the back of the backpack can be attached using the included cord to further reduce weight.
