The SUNWILL 20oz Tumbler with Lid is one of the most popular double-wall insulated stainless steel coffee mugs in the market, with a cumulative rating of 4.5 out of 5. Its fame among users comes from its high-quality design and impressive insulation capabilities. Despite this, there are a few considerations which some users have found less favorable.

Summary

SUNWILL’s 20 oz tumbler is known for its impressive heat retention capability, thanks to its Double-Wall vacuum insulation technology.

The mug is made from high-quality 18/8 304 food grade stainless steel, making it lead-free, rust-proof, and nearly unbreakable.

A defining feature of this mug is its superior powder coated finish. This advanced technology ensures that the mug remains sweat proof, offers easy grip and prevents heat transfer to the outer wall.

The tumbler features a BPA free sliding lid, which is both eco-friendly and splash-proof. The lid design also includes a drink hole for easy sipping, and is conveniently straw-friendly. However, unlike other mugs on the market, some users report that the lid does hinder the flow of the beverage.
