If you only want the pick: CoreFlow at ₹899. Full reasoning below.
Why the CoreFlow Exists
There's a meaningful gap between uncertified cheap bottles (₹200–700) and the mid-range HYV line (₹999+). The CoreFlow fills it: genuine vacuum insulation, genuine, genuine 18/8 stainless steel interior, at ₹899. No silicone boot, no special lid mechanism, no wide colour range — just the insulation.

💡 The ₹100 Question
FlipFlow at ₹999 is ₹100 more than the CoreFlow. That ₹100 buys the quick-flip one-thumb lid. If you're primarily using the bottle at a desk, the CoreFlow screw cap is fine. If you're at the gym or cycling, the FlipFlow's one-thumb access is worth the ₹100 extra.
