Hello! I'm looking for a reusable water bottle with certain characteristics, and am hoping for some recommendations:

• Made of stainless steel, or another long-lasting, non-degrading material that doesn't change colour or absorb the flavour of the drinks inside
• You would trust it not to leak in your bag
• Supports both hot and cold drinks
• Has a straw
• Individually replaceable difficult-to-clean parts (e.g. straw, mouthpiece)
  • Bonus points if these parts are sold separately
  • Extra bonus points if there are interoperable multiple vendors for these parts! (not sure if that's realistic, but I'll include this anyway :))
• Easy to clean, either by hand or in the dishwasher
• Sold in the UK
• And of course, that lasts a long time!

I'd ideally like one with all of these characteristics, but feel free to comment bottles that don't match perfectly, in case that's useful to others.

Edit: thank you so much everyone for the suggestions! I ended up buying a Klean Kanteen Classic Water Bottle. It arrived yesterday and so far so good! Will edit again if anything goes wrong with it in the next 10 years :D
