Sea To Summit Trek & Travel Liquid Conditioning Shampoo 100ml

Sea to Summit's Trek & Travel Liquid Conditioning Shampoo is a 100 ml biodegradable 2-in-1 shampoo and conditioner with a light green tea scent, in liquid form. Being biodegradable matters if you're washing near streams or lakes on trail, where standard shampoo and conditioner residue can affect water quality. At 100 ml it's sized for cabin-baggage rules on flights as well as trail use, and combining shampoo and conditioner in one bottle saves carrying two separate products. It isn't scent-free, so anyone sensitive to fragrance or trying to avoid attracting wildlife with scented products should factor that in.
