This is a North Face Mayfly Hip Pouch. I bought it, but I haven't had a chance to use it, so I'm selling it. The color is silver gray. This is a lightweight, compact multi-pouch suitable for use with a large pack. The main material is TX70 Ultra, a high-performance material from CHALLENGE SAILCLOTH's ULTRA series, using UHMWPE (ultra-high molecular weight polyethylene), which boasts approximately 15 times the strength of steel by weight. It is thin and lightweight, yet resistant to tearing and abrasion, and has excellent durability. The daisy chain on the front side is convenient for connecting small items. It has a 2.5-liter capacity, making it easy to use in various situations.
