SIP Airtight Drinking Valve

A safer, sealed way to drink through a mask with a straw!  

SIP is an AIRTIGHT VALVE that grips around the straw and automatically SEALS after each sip, allowing you to drink while keeping your mask on.

Unlike other products (holes, flaps, zippers) that put a hole right in front of your mouth), SIP's airtight seal has been developed and tested to protect the efficacy of your mask (ie, no air leaks!).

Key features:

• Airtight seal does not sacrifice mask efficacy 
• Reusable:  Can be installed up to 10 times on different masks.  Replenish every 30 days if used daily.
• Washable (dishwasher safe)
• Made from food grade silicone that provides a soft touch on your lips
