GSI Microlite Flask 720 Twist


Streamlined, tough, lightweight – the Microlite 720 Twist holds the cold for 24 hours, and keeps the heat for 12. The advanced engineering used means the walls are impossibly thin at 2mm resulting in a good, lightweight flask that still has a durable performance. The 18/8 stainless steel is tough and pure, and the secure twist-top is engineered for easy opening – even with gloves on.


What do SKO think? We have tested the 1L flasks that have dealt with rolling around in our hatches for two seasons now and we are thoroughly impressed with how rugged they are. We are now trying the Microlite 720 Twist because the lightweight aspect is a massive win for portages as we tend to carry a fair amount of kit in our boats. We can say that the contents of the flask are still hot the next day which means we don’t need to worry about getting up earlier in the morning on expedition to make that all important brew to kick start our day.
