The CrossOver by Sativa Hemp Bags - It is what it says€¦ Bum Bags are created for storing your basics, great for festivals, parties and days out but often you are restricted with what you can fit due to the size. Alongside selling the commonly sized bum bag we have now designed an oversized bum bag. This is now the perfect accessory for days out where you want to carry more than your smaller basics. This provides a great alternative style to a mini rucksack with the ideal number of pockets on the front, back and inside the bag. Worn across the front or back of your body this bag is a cool and easy way to elevate your street wear outfits.
