Zojirushi Food Jar SW-KA Light Blue from 300 ml (10.15 oz) up to 750 ml (25.35 oz)

Opening the Zojirushi SW-KA food flask after a winter walk in Dublin felt like bringing a hot home-cooked meal outdoors. What impressed me most wasn’t just the sleek design — it was how my soup was still steaming hot six hours later. Since then, this series has become my favourite recommendation for families, students, and outdoor enthusiasts across Ireland & the UK.

Available in 300 ml, 520 ml, and 750 ml sizes, the SW-KA Series offers something for everyone: a light children’s food thermos for school, a compact hot food flask for office or university, and a large soup flask for outdoor meals. Thanks to Japanese vacuum insulation, food stays hot (up to 68°C after 6 hrs) or chilled (down to 9°C after 6 hrs).

Why it’s perfect

• Parents → the 300 ml size is ideal as a children’s food thermos for porridge, pasta, or fruit

• Office workers & students → the 520 ml food flask for hot food keeps lunch warm until break

• Outdoor lovers → the 750 ml vacuum flask food is perfect for stews, noodles, or a hearty flask of soup on hikes or fishing trips
