Two modes: sip upright through the built-in straw, or tilt the bottle back and drink from the wide-mouth FreeSip spout (patented).
Owala FreeSip bottles are offered in multiple capacities, commonly 16‑ounce, 24‑ounce, 32‑ounce, and 40‑ounce models.
The bottle bodies are stainless steel and the lids are made from plastic, per product details.
Listings highlight leak‑resistant seals, a protective push‑to‑open cap that keeps the spout covered, and a carry loop that can double as a lock to help prevent accidental opening and leaks.
The FreeSip line offers several lid styles, including drink‑through flip‑top lids, push‑button lids, straw lids, and wide‑mouth push‑button lids—availability varies by model.
Listings commonly state the bottles are BPA‑free and lead‑free, and several also note they are phthalate‑free.
