Review on Waterproof Red Small Sling Bag - Elfhao Chest Shoulder Backpack for Gym, Outdoor, Crossbody - Daypack for Men, Women, and Kids (One Size) by Brad Knierim

I love this shoulder bag. It's lightweight yet durable. I use it when I go hiking or walking. I usually pack 2-3 16 ounce bottles of water in my bag. There's still enough room in my bag for ID, lip balm, a small amount of sunscreen, a small first-aid kit, pepper spray and keys. I prefer not to put water bottles in the mesh pockets on the outside of the bag. However, I put a small/mini umbrella in the mesh pockets and it fits in well. I can't confirm the waterproofness as the bag hasn't gotten wet yet. I like the comfortable strap and the flexibility to wear the bag on the front or back.
