Robert ★★★★★ Oct 26, 2026

My coffee is still hot after a 3-hour hike, which honestly shocked me. The flip cap seals tight enough that it hasn’t leaked once in my backpack, and 400ml is the perfect size for a solo day trip.

I’ve been using this flask for a week and the double wall insulation keeps my coffee hot for hours. The flip cap is super convenient for one-handed drinking while I’m working.

This 400ml size is perfect for my daily commute—fits most cup holders without being bulky. The double-wall insulation keeps my coffee hot for hours, which is a pleasant surprise.
