Backpack Exchange, an exchange that cares about the health of watering staff. The best gift ever received from project parties. Really grateful for the STANLEY cup from Backpack. Otherwise, I would definitely have suffered from heatstroke while camping today. I am someone who doesn't like to drink water because I think water has a very strange taste, especially warm water. Before I got this cup, I only drank coffee, tea, juice, and milk. Since receiving the cup from Backpack Exchange, I now drink 2 liters of iced lemonade every day. The ice retention effect is amazing. Yesterday's ice didn't melt today in the outdoors under the scorching heat of over 30 degrees. 😋
