Two lids, two drinking styles
The Mizu Sip Through Lid and Straw Lid look similar at a glance, but they serve different drinking habits and fit different bottles. The Sip Through Lid is a press-on cap for warm or cold drinks, while the Straw Lid is a flip-up design with a cut-to-length straw for wide-mouth bottles. Before you pick one, check the bottle compatibility and whether you use a filter—those two factors often decide it.
Sip Through Lid vs Straw Lid at a glance
- Sip Through Lid: Press-on fit for Camp Cup, Coffee Mug, Tumbler 20, and Tumbler 16; 0.7 in / 17 mm height, 3.3 in / 84 mm diameter, 0.7 oz / 20 gm; six colors.
- Straw Lid: Fits all wide-mouth bottles (M Wide & V Wide Series); flip-up handle and spout; includes cut-to-length straw; 1.6 in / 40 mm closed height, 2.3 in / 58 mm open, 3 in / 75 mm diameter, 3.5 oz / 98 gm; eight colors.
Which bottles each lid fits
The Sip Through Lid is designed for Mizu drinkware with a matching rim: Camp Cup, Coffee Mug, Tumbler 20, and Tumbler 16. It presses on—no threads—so it is not intended for wide-mouth water bottles. The Straw Lid is the opposite: it fits all wide-mouth bottles in the M Wide and V Wide Series. For V Wide bottles, note that this lid fits bottles purchased on or after March 1, 2017; older bottles may need a different replacement lid, and Mizu support can help you confirm.

Straw Lid: key specs for wide-mouth bottle users
-
Straw Lid: Compatible with all wide-mouth bottles (M Wide & V Wide Series). Fits your existing wide-mouth bottle if it is from these series.
Straw Lid
-
Straw Lid: Includes a straw that can be cut to any length for M Wide or V Wide bottles. One lid adapts to different bottle heights.
-
Straw Lid: Height closed 1.6 in / 40 mm; open 2.3 in / 58 mm; diameter 3 in / 75 mm; weight 3.5 oz / 98 gm. Taller and heavier than the Sip Through Lid; consider clearance and weight.
-
Straw Lid: Insulated: No. The lid itself does not add insulation; rely on your bottle for temperature retention.
Filter compatibility: a deciding factor
If you use an Everyday Filter or Adventure Purifier, the Straw Lid requires a separate Filter Adapter (sold separately). The Sip Through Lid has no listed filter compatibility, so it is not the lid to choose if filtration is part of your routine. This is the clearest functional difference between the two.
Choose by your daily routine
- You drink from a Camp Cup, Coffee Mug, or Tumbler: The Sip Through Lid is the direct fit; no straw to manage.
- You carry a wide-mouth water bottle and like sipping through a straw: The Straw Lid with its cut-to-length straw is designed for that.
- You use a water filter: The Straw Lid plus Filter Adapter is the compatible path; the Sip Through Lid does not list filter support.
- You want a low-profile, lightweight lid: The Sip Through Lid is 0.7 in / 17 mm tall and 0.7 oz / 20 gm; the Straw Lid is 1.6 in / 40 mm closed and 3.5 oz / 98 gm.
What the supplied information does not settle
Neither lid's record includes care instructions or leak-performance claims, so we cannot confirm dishwasher safety or leakproofness from the available details. For the Straw Lid, the note about V Wide bottles purchased before March 1, 2017 suggests checking with Mizu support if your bottle is older. The Sip Through Lid's press-on fit means it is not a threaded cap; ensure your cup's rim matches the 3.3 in / 84 mm diameter.
