Quick answer
Choose the Growler Lid if you own a 64oz MiiR Growler or 32oz Howler and need a handled replacement lid for beer or bulk beverages. Choose the Leakproof Chug Lid if you want a high-flow spout with a locking cap for everyday cold drinks on the move. They are not interchangeable, so match the lid to your vessel first.
Why the vessel decides the lid
MiiR lids are built for specific vessel families, not universal threading. The Growler Lid is intended for the 64oz Growler and can also be used with the 32oz Howler, but it is not intended for other vessels. If you try to force it onto a different bottle, you risk a poor seal or a lid that will not stay put.
64oz Growler
The Leakproof Chug Lid is designed for Wide Mouth Bottles, including the MiiR x Carryology Wide Mouth Bottle. It is not a growler replacement. Before you buy, confirm the vessel name and size on the bottom of your bottle. If you are unsure, check the product page for your exact bottle or contact MiiR support with a photo of the vessel opening.
Wide Mouth
Growler Lid: handled, beer-ready, and vessel-specific
The Growler Lid ships as a handled lid only, with no vessel included. It is a practical replacement if you lost the original lid on your 64oz Growler or 32oz Howler and want to keep using the same vessel. The handle makes it easier to carry a full growler, and the lid is intended for beer and other bulk beverages.
Care is simple: wash before first use, hand wash recommended, and the lid is top rack dishwasher safe. Do not freeze, do not microwave, do not bleach, and do not overfill. Because it is not intended for other vessels, do not buy it as a general spare lid for a Wide Mouth Bottle.
Leakproof Chug Lid: high-flow spout for daily hydration
The Leakproof Chug Lid is an everyday accessory for Wide Mouth Bottles. It has a strengthened hinge and a high-flow spout designed to protect itself when not in use. A locking cap twists open, flips back, and stays put with a click, which helps prevent the lid from swinging into your face while you drink.
The lid keeps your beverage cold for hours, according to the catalog description. Care instructions are the same pattern: wash before first use, hand wash recommended, and the lid is top rack dishwasher safe. Do not freeze, do not microwave, do not bleach, and do not overfill. This is the lid to choose if you want one-handed drinking during a commute, walk, or workout.
Replacement lids for 750ml Bottles and other MiiR vessels
If you own a 750ml Bottle, the 750ml Bottle Lid is the direct replacement. It follows the same care rules: wash before first use, hand wash recommended, top rack dishwasher safe, and do not freeze, microwave, bleach, or overfill. Note the choking hazard warning: it may contain small parts not suitable for children under 3 years.
Do not assume a Growler Lid or Chug Lid will fit a 750ml Bottle. The 750ml Bottle Lid exists because that vessel has its own fit. When shopping for a MiiR bottle lid replacement, start with the vessel name and size, then pick the matching lid.
Decision rules for choosing a MiiR lid
- If you own a 64oz Growler or 32oz Howler: Buy the Growler Lid. It is the only lid in this set intended for those vessels, and it ships as a handled lid only. Do not buy it for a Wide Mouth Bottle or 750ml Bottle.
- If you own a Wide Mouth Bottle, including the MiiR x Carryology Wide Mouth Bottle: Buy the Leakproof Chug Lid for high-flow drinking with a locking cap that clicks into place. This is the lid for commuting, hiking, and gym use.
- If you own a 750ml Bottle: Buy the 750ml Bottle Lid. It is the direct replacement for that vessel and carries a choking hazard warning for small parts. Keep small parts away from children under 3.
- If you are unsure of your vessel size: Check the bottom of the bottle or the product page before ordering. MiiR lids are vessel-specific, and the catalog does not list universal compatibility. When in doubt, contact MiiR support with your bottle model.
Product facts
- MiiR x Carryology Wide Mouth Bottle: MiiR x Carryology Wide Mouth Bottle is a special edition 20oz and 32oz Wide Mouth Bottle with Carryology's Auxikko pattern, inspired by samurai armor and Japanese geometric patterns. This is a Wide Mouth Bottle, so it pairs with Wide Mouth lids like the Leakproof Chug Lid, not the Growler Lid.
- Leakproof Chug Lid: Leakproof Chug Lid has a strengthened hinge, a high-flow spout designed to protect itself when not in use, and a locking cap that twists open, flips back, and stays put with a click. The locking cap and high-flow spout make it a strong choice for one-handed drinking and active use.
- Growler Lid: Growler Lid is intended for use with the 64oz MiiR Growler, but can be used with the 32oz MiiR Howler. It ships with handled lid only, vessel not included, and is not intended for use with other vessels. Buy it only if you own a 64oz Growler or 32oz Howler and need a handled replacement lid.
- 750ml Bottle Lid: 750ml Bottle Lid is a replacement lid for your 750ml Bottle. It has a choking hazard warning: may contain small parts not suitable for children under 3 years. This is the correct replacement for a 750ml Bottle, and the warning matters if you have young children at home.
