Took this flask out on a seven hour gravel baptism. Was about 70% boiling, 30% cold mix. Was perfect temp to drink for around two hours. Then began to cool, more cold air volume and sloshing; I’m sure there is a scientific way of putting that. By end of ride, a frosty cold day, still tepid. I reckon for a long day, 100% boiling would last well into the latter stages.
One handed design does work, getting it back into my cage with a wet glove on the move… it went in and stayed in. I’d wondered if it would stay in over rough ground, with no depression as such to key it in. It didn’t budge even when empty and finding a rocky descent.
It’s going to get so battered and scratched though. It’s going to be great!
