What reviewers say
Owner ratings are good but based on few reviews: about 4.3 of 5 at REI and 4.6 at Backcountry. People like that it is easy to clean, doesn't leak, and feels sturdier than all-silicone cups. One three-star review said it only worked well for cold drinks, and the maker itself warns the mug can get hot with hot contents, so expect warm hands with fresh coffee. Retailer weight figures don't agree.
Good
- Packs very flat
- Steel base feels sturdy
- Easy to clean
Not so good
- Can get hot to hold with hot drinks
- Small number of owner reviews
- Heavier than plastic collapsible cups
Who it's for
Campers and paddlers who want a real mug that packs small. If you drink a lot of hot coffee and space isn't tight, an insulated mug is more comfortable.
