ThermoFlask Stainless Steel Bottles 950ml: 2 for $27.00 in-store or $37.99 Delivered @ Costco Wholesale (Membership Required)
If you've been burned by leaky bottles before (literally), here's one I've personally used for years without a single issue. You can grab two 950ml ThermoFlask bottles for just $27 in-store at Costco, or $37.99 delivered if you'd rather skip the trip.
- Double-wall vacuum insulation keeps drinks cold for 24 hours or hot for 12
- Leakproof, dishwasher safe, and free from BPA, PFAS and lead
- Only $7 more delivered, but you'll need a Costco membership either way
Honestly, at roughly $13.50 per bottle in-store, this is hard to beat for a brand that actually holds up.
