Review on 💦 Stay Refreshed on the Go with the Hydro Flask Insulated Standard Mouth Sport Cap by Jorge Tupou

Mandatory not to open and close the bottle but I have noticed that it is leaking from the valve at the top center of the lid (this is not visible in the picture) Keep the Backpack up, otherwise coffee or hot tea may spill into a backpack or onto the floor. He also whistles when you drink to him. So the claim that it is not listed on Revain and on the HydroFlask website is misleading in my opinion. I also noticed that the HydroFlask website states that the sports cap is not airtight. Disappointed that such important information is not displayed on the Amazon website. it really only says: - Compatible with all common mouth bottles - Insulated for increased temperature protection - Silent valve without whistle - Free from BPA and phthalate
