Performance
Single-wall stainless does exactly what it promises — durable, easy to clean, filter-compatible. The wide mouth makes filling fast and drinking natural, and the loop cap seals tight without fuss. Temperature control isn't the story here: the thin walls conduct temperature efficiently, which means ice melts faster on a hot day than with an insulated bottle. That's the trade-off, and it's a fair one for anyone who doesn't need all-day cold.
