Arc Water Bottle Pocket
Good product replacing one I lost yrs ago - also tarmac and also have 3 tarmac bags of various sizes and love ‘em all!
I recently purchased this product and I can not be more than satisfied. I've given quite use my mountain outings to do landscape photography and mainly nocturnal and is a useful, durable and necessary item as an ideal complement to my backpack.
I have used this as both a water bottle holder as well as a lens holder and it works great.
