Waterfly FP01-04 Bum Bag – Brown, 1.5L RFID Anti-Theft Waist & Crossbody Pack

Waterfly bum bag: brown RFID anti-theft waist and crossbody pack

Practical, lightweight and genuinely useful for day-to-day adventures. The Waterfly FP01-04 keeps your essentials close and secure without the faff of a big rucksack. At just 170g with a 1.5L capacity, it will hold your phone, wallet, passport and keys without feeling bulky or getting in the way.

Built to handle everyday life

Made from hard-wearing 500D nylon with a PU coating, the fabric stands up to scuffs and light rain — splash-resistant rather than fully waterproof, so don’t leave it out in a proper downpour. Smooth, two-way SBS zippers make getting at your kit quick and fuss-free, and the elasticated drawcord is a neat, practical touch that keeps everything tidy.

Security without stress

Designed for travel and busy days, the pack combines two solid anti-theft features: a lockable front zipper for physical security and a hidden back pocket lined with RFID-blocking material to stop unauthorised scans of cards and passports. That extra peace of mind is especially handy on crowded trains, at festivals or around tourist hotspots.

• Dimensions and capacity: 23 x 13 x 5 cm (9 x 5.1 x 1.97 in); 1.5L capacity; lightweight at 170g.
• Strap and fit: adjustable strap from 62 to 120 cm (24.4 – 47.2 in) so it fits most waists and can be worn as a crossbody or chest bag.
• Comfort and visibility: breathable mesh padding on the back for airflow and a reflective cord for increased visibility in low light.
• Security features: lockable front zipper and hidden RFID-lined pocket protect valuables from pickpockets and electronic theft.
• Everyday uses: great for travel, hiking, running, cycling, dog walks, festivals and general city life.

Practical notes and tips

It’s not intended for heavy or bulky items — think everyday carry for the essentials rather than a mini kitbag. If you’re carrying sensitive items in wet conditions, pop them in an internal dry pouch: the PU coating handles light showers but isn’t completely waterproof. The strap adjusts quickly, so whether you’re plus-size or petite you’ll get a comfy fit and can switch from waist to crossbody in seconds.

A year of support is included from the date of purchase, which is handy if anything feels off. All told, it’s a tidy, sensible little pack that saves time and keeps the important stuff close — no more rifling about in pockets or bag chaos.
