Compare the Classic Steel Loop Cap and the Wide Loop Cap with Bale from Klean Kanteen. Learn which cap fits your bottle and drinking habits best.
Quick answer
Choose the Wide Loop Cap with Bale if you own a wide mouth bottle and want a 100% stainless interior. Choose the Classic Steel Loop Cap for narrow mouth bottles that require internal threads.
Threading and compatibility
The most important difference between these two caps is the threading. The Wide Loop Cap with Bale works with wide mouth bottles that have external threads. The Classic Steel Loop Cap is designed for classic narrow mouth bottles with internal threads. Using the wrong cap will not create a seal and can lead to leaks.
Always check your bottle's mouth size and thread location before choosing a cap. The Wide Loop Cap is not interchangeable with narrow mouth bottles, and the Classic Steel Loop Cap will not fit wide mouth bottles.
Material and drinking experience
Both caps are made from 18/8 food-grade stainless steel, but the Wide Loop Cap with Bale creates a 100% stainless steel environment inside your bottle. This means your drinks never touch plastic, which is ideal if you prefer a pure stainless taste. The Classic Steel Loop Cap also includes stainless steel threads, so your drinks do not touch plastic either.
The Wide Loop Cap features a swivel bale that makes it easy to carry. The Classic Steel Loop Cap has a loop design but lacks the bale. If you frequently carry your bottle by the cap, the bale adds convenience.
Hot beverages and dishwasher safety
Both caps are dishwasher safe for easy cleaning. However, the Classic Steel Loop Cap is not intended for use with hot beverages. If you plan to drink coffee, tea, or other hot drinks from your bottle, the Wide Loop Cap with Bale is a better choice because it does not have this restriction. The Wide Loop Cap is leakproof and can handle hot liquids safely.
