This is an AMAZING solution for foragers of all kinds.
Three swappable inserts allow maximum creativity with use: the foraging mesh keeps delicate mushrooms dry, the canvas sack is perfect for groceries, and the watertight PEVA insert keeps fresh cut flowers hydrated. The internal plastic frame on top and bottom acts as a bucket, which keeps contents spacious and safe. Comfortable multi-way straps can be used as a sling or wrapped around the waist for ease while foraging. Constructed of our tried and true weather- and water-resistant paraffin waxed canvas (ie - you may just pass this on to your grandkids!).
For mushroom foraging, we love that we can head out with all three inserts in the bag, and if we have a big haul use each one as its own satchel, with plenty of ways to hook it onto the main bag frame. The open mesh bottom is also great for letting mushrooms breathe, and the waterproof bag can be used to make spore slurries right in the field if you're hoping to help the mushrooms expand their range for next year.
