Flex Bag — a new format of versatile bag from Blackpack
Keeping the philosophy of the Flex line, the XL version offers significantly more space while remaining just as comfortable and ergonomic. It’s the perfect hybrid that combines the lightness of a bag with the capacity of a small backpack. It adapts to its contents: when there’s minimal stuff inside — the bag hugs the body and is barely noticeable, and when needed it fits a laptop, lunch, warm clothes, and gear.
Organization and functionality
Internal space and EDC: The space organization allows you to conveniently fit both large items and small accessories.
Large fleece pocket: A special compartment with soft lining fits an iPad or portable gaming console, protecting the screen from scratches.
Side holders: Elastic bands inside allow you to place a thermal mug, bottle, or secure gear with a clip.
Organizer: A well-thought-out pocket system for EDC essentials to keep everything in its place.
Main compartment
The main compartment has been significantly expanded. It easily fits a MacBook Pro 14″ (in a protective case) — the bag is not specialized for laptops, but allows you to comfortably transport one. Bulky items: a lunch container, camera, raincoat, or water bottle. Access to the compartment is wide and convenient, allowing you to quickly grab what you need on the go.
Material
Flex Bag XL is made from innovative UltraGrid™ material by Challenge Sailcloth. It’s a fabric made from recycled nylon yarn, reinforced with a double grid of 200d fibers. It provides exceptional durability while maintaining flexibility. Thanks to this, the bag perfectly follows the shape of your body and doesn’t create the feeling of a rigid “box” on your back. Features water-resistant AquaGuard zippers and reliable hardware.
What’s included
The bag is compatible with Blackpack’s universal strap system. It’s convenient to wear over the shoulder or on your back. The strap can be removed and swapped from another bag you own (for example, the regular Flex Bag or a waist pack).
Strap sold separately.















Pavlo –
Optimal crossbody sling format to throw in a small laptop, my MBPro 14″ fits even in a case. Enough pockets and compartments for any amount of stuff and accessories. There’s space for a bottle inside.
When riding a bike it’s really convenient that there’s an additional attachment strap, it lets you secure the bag reliably and it won’t bounce around while moving.

Дуже зручна та легка сумка, не врізається та не давить у плече. Багато кишень та місця для речей, дуже задоволений.
