No. Over a decade ago, Hydro Flask [pioneered an alternative sealing process](https://nam02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.inc.com%2Falix-stuart%2F2015-inc5000-how-this-company-overcame-a-toxic-disaster.html&data=05%7C02%7Clalberg%40helenoftroy.com%7C4643151db5924403907e08dc2088ded0%7C956da9b4455a45908de8f66d6885fdd5%7C0%7C0%7C638421019415417790%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=ddjnQ1ARsFlJ%2F19tHKORUdTHosAQAEBheZxXxN2H4x4%3D&reserved=0 "https://nam02.safelinks.protection.outlook.com/?url=https%3a%2f%2fwww.inc.com%2falix-stuart%2f2015-inc5000-how-this-company-overcame-a-toxic-disaster.html&data=05%7c02%7clalberg%40helenoftroy.com%7c4643151db5924403907e08dc2088ded0%7c956da9b4455a45908de8f66d6885fdd5%7c0%7c0%7c638421019415417790%7cunknown%7ctwfpbgzsb3d8eyjwijoimc4wljawmdailcjqijoiv2lumziilcjbtii6ik1hawwilcjxvci6mn0%3d%7c3000%7c%7c%7c&sdata=ddjnq1arsflj%2f19thkorudthosaqaebhezxxxn2h4x4%3d&reserved=0") for vacuum insulated bottles. In 2012, we moved away from what was at that the time the industry standard vacuum sealing process and toward an innovative process that sealed our bottles without the use of lead. 

Even though this new process was more complex – and more expensive – we chose this path because we aimed for a higher standard knowing lead could be harmful to consumers, manufacturing partners and the environment.
