20oz Stanley AeroLight™ Transit Bottle: Everyday Hydration → System Transformation.

A water bottle keeps you fueled on the outside.
51& keeps you fueled on the inside — from better care to better policy.
Carry it, and help build the system women deserve.

Engineered for women on the move, this feather-light Stanley AeroLight™ bottle is one-third lighter than standard stainless steel without losing an ounce of durability or thermal performance. Whether you’re heading to work, school pickup, the gym, or the next big meeting, this bottle keeps your water cold from your first sip of the day to long after quitting time.

The low-profile design slips easily into bags and cup holders, and the locking, drink-through lid stays leakproof — so your essentials stay protected while you protect the future of women’s health.

100% of profits from this item are reinvested directly into fixing what’s broken in women’s health — funding research, better coverage, and real system change.

Made in exclusive 51& colorways, this bottle brings together best-in-class engineering and member-powered system change. Hydrate with purpose.
