My new favorite bottle!

Got the matte finish bottle last week, it's just superb! Kept my chai hot all through my morning commute. The quality feels so premium. Will definitely be ordering more for gifts!

Good, reliable bottles for office

This was my third time buying from Thermosteel, ordered the insulated tumbler this time. As usual, delivery was quick – took only 4 days to reach Bangalore. The tumbler is great for my coffee, keeps it warm for hours. My previous wide mouth flask is still going strong after a year. Always good value here, that's why I keep coming back.

Hey, thinking of getting a new water bottle from here. How long does shipping usually take to Bangalore? And can I pay cash on delivery?

A Ashmal KK 2 months ago

Shipping times vary a bit but I got mine in like 5 days to Chennai last month. Not sure about Bangalore specifically though. And yeah, COD usually works, used it for my last order.

Afaik, they don't do international shipping so probably pretty quick within India. COD is usually an option during checkout, just make sure to select it.

Are these bottles actually good quality? Like, how do they compare to a Hydro Flask? I've heard good things but want to make sure it's not some cheap knockoff.

H Hemanth Nethi 1 month ago

Yeah, they're legit. I have both a Thermosteel and a Hydro Flask, and honestly the Thermosteel keeps my drinks cold just as long, sometimes even better. Definitely not a knockoff.

V Veda Co 1 month ago

My friend has one and swears by it. Holds ice for ages. Plus, the price point is usually way better than Hydro Flask for pretty much the same performance.
