The Black Ember TKS (Tech-Kit Sling) is an item I personally imported from the US in 2021. I like this brand and have used various bags from them. I've only used it on weekend outings, and there's no noticeable damage. I used it as a body bag, slung diagonally across my body. The TKS body comes with a magnetic key ring. This is a high-performance tech kit that can also be transformed into a sling bag. You can pull out the built-in belt on the back panel and secure it with a Fidlock® magnetic V-buckle to convert it into a sling. It boasts high water resistance with YKK® AquaGuard zippers and its unique BOND-STITCH™ construction, and it also has excellent storage capacity. Inside, it's equipped with an accordion-style organizer (6 pockets) and an elastic mesh pocket. You can organize and store larger items and electronic devices. It's ideal for carrying gadgets, with space for smartphones, chargers, and a unique cord pass-through. The outer pocket has a Maglock key chain for quick access to keys. The zipper pulls have anti-theft locks for peace of mind. The new CORDURA® re/cor™ RN66 (100% recycled nylon) material is durable and weather-resistant, and also reduces environmental impact. High-precision laser cutting gives it an overall minimalist and sophisticated appearance. The specifications are size 28 x 14 x 7.62cm (capacity 2.5L), with a maximum circumference of 157cm. High-quality materials are used for the main materials and parts, such as aircraft-grade aluminum, Hypalon, and 200D ripstop lining. The TKS is a versatile sling bag that combines excellent organization with water resistance, durability, and functional beauty.
