Didn’t think it would matter this much. But the water stayed cold the whole session, no heat or weird taste.
I use it every session now. No more warm water or burnt lips. Fast shipping!
Didn’t think it’d stay cold. It did, even after a 1h combined session in the sauna.
Didn’t really think about it during the session, which is probably the best sign. Water stayed cold.
Feels solid. Water stays cold. Doesn’t heat up like my old plastic bottles.
Used this today and the water stayed cold the whole time. Shipping took 3 days.
On point performance. Ive tried multiple thermos but this is the best so far.
Both items exceeded my expectations. Looks good, works even better. Would buy again.
