Grey canvas tote with red zipper pocket

I lost my grey Herschel tote yesterday around 3pm near the Sundial Bridge by Turtle Bay Exploration Park in Redding. It's a medium-sized canvas bag with a bright red zipper pocket on the front and a small blue tassel hanging from the zipper. Inside I keep a spiral notebook, a black stainless steel bottle, and a folded Shasta County map. The lining has a panda sticker near the inner pocket, and there's a tiny tear at the bottom left from a hiking trip. This is a Miscellaneous Bags listing, and it really matters to me because it was a gift from my sister, and I’m really hoping someone who finds it will return it.
