Meet the Batohiro KAI S – the latest addition to our range of waist bags for everyday carry. Created for a dynamic lifestyle, versatile use, and 3 ways to wear.
Designed to provide complete visibility, extreme durability, and a clean unisex look. This isn’t just another “waist bag”; it’s your organized partner for good times and bad, handmade in the heart of Prague.
The greatest advantage of the KAI S is its construction - clear interior organization and a versatile design. Forget narrow openings that barely let you fit your hand through. The waist bag’s key design feature is its full-perimeter zipper - KAI S opens completely.
With our Zipline concept, you can open the waist bag wide, access all the organizers at once, and immediately see everything you need. Your phone, wallet, headphones, power bank, lip balm – everything has its designated place in the carefully designed organizer system. No more chaos.
KAI S is a paradise for organization lovers. The interior and exterior are divided into several functional zones:
- In the lid: A zippered pocket for all your essentials (tissues, chewing gum), or simply the things you need to have close at hand every five minutes; elastic loops for pens, cosmetics, or cables; and a flat pocket for business cards or tickets.
- Rear security pocket: on the side closest to your body, protecting your valuables (ID documents, passport, phone, cash) directly against your body when you’re traveling, on vacation, moving through a crowd at a festival or a concert by your favorite band, or enjoying an unforgettable atmosphere and a long night at the club.
- In the main compartment: Two mesh zippered pockets that let you see what’s inside at a glance, plus an essential integrated carabiner key loop.
Wearing it in the city, while traveling, or at festivals requires a material that can withstand anything. That’s why the KAI S is made from waterproof CORDURA® 500D, a material legendary among outdoor enthusiasts for its extreme resistance to abrasion, tearing, and moisture. Not only does it look great, but it will last for years (even with rough handling).
- The waist bag is fitted with high-quality water-resistant YKK® zippers that help prevent dust and water from getting inside.
- Straps that are long and wide enough to carry your essentials.
- A sturdy, ergonomically sewn attachment for maximum comfort when worn across the body, so it doesn’t dig in or get in the way.
Wearing options and practical uses
Thanks to its adjustable straps made from durable material and its compact dimensions, the waist bag can be adapted to different situations:
· Crossbody on the chest: The most common way to wear it, with the strap shortened so the bag sits snugly against your chest. This provides the highest level of security in crowds (concerts, festivals, public transportation) and easy access to your essentials or phone.
· Over the shoulder: A more formal urban style - lengthen the strap for everyday wear at your side. You can wear the waist bag casually over your shoulder like a classic handbag or small purse.
· Around the waist: A classic, freedom-of-movement-friendly fit - traditionally worn on the hips or waist, leaving your hands and upper body completely free. Practical for sports, cycling, hiking, longer walks, or for parents with children.
KAI S has thoughtfully designed dimensions of 20 × 13 × 7 cm, allowing it to hold the standard essentials you need every day — a smartphone, wallet, keys, (power bank), small personal hygiene items, a snack, a water bottle of up to 500 ml, or your favorite beer.
KAI S proves that even a “small” waist bag can make a big difference to your everyday life. It combines honest craftsmanship, premium materials, and intelligent design that you’ll appreciate every time you open it wide.
Built to Last. Be the Hiro.
