Bum Bag Micro is a downscaled version of Rains’ signature bum bag. It’s micro, yet big enough to fit daily essentials.



Bum Bag Micro holds just about everything you need - card, key and phone. It’s designed for optimal functionality when on-the-move. The waterproof design features a single main compartment, coated zip closure for easy access and a comfortable mesh panel at the back.



Bum Bag Micro is fixed to an adjustable webbing strap and fastens with a convenient quick-release buckle. The design is perfectly formed and can be worn over the shoulder, as a cross body bag or as a waist belt depending on preference and everyday-need.



Bum Bag Micro is cut from Rains’ signature waterproof PU fabric, engineered for carrying strength, durability and a smooth feel.

Avery B. ★★★★★

Took this to a festival and it held my phone, cards and keys without bulging under my jacket. The matte finish wipes clean easily, which mattered after a muddy day. Small enough that I forgot I was wearing it.

Miles O. ★★★★★

The magnetic closure snaps shut with a satisfying click, and the strap sits snug against my hip without bouncing around. I’ve loaded it with my phone, keys, and a card, and there’s still a little breathing room—perfect for a quick errand or a day out. It’s become my go-to when I don’t want to carry
