## Our take

A 1.18 litre double-wall vacuum insulated stainless steel tumbler with a three-position rotating lid and a reusable straw. It is built to keep a serious volume of cold water (or anything else) genuinely cold for an entire day out, and the narrow base is sized to drop into a golf cart or car cup holder.

**What's great:** The insulation lives up to the claim, ice cubes are still rattling around hours into a hot round, and the sheer size means fewer trips to the halfway house tap. The rotating lid is genuinely useful, flip it to full-cover when it is bouncing around in the cart, open the straw hole when you want a quick sip mid-fairway. The handle makes it easy to grab one-handed, and the whole thing is reassuringly solid.

**Worth knowing:** It is big and heavy when full, which is fine in a cart but a chore if you walk and carry. The lid is not leakproof, lay it on its side in your bag and it will weep, so it travels best upright in a holder. The straw and lid have fiddly nooks that need proper cleaning or they get grim, and it is more expensive than a plain flask doing the same insulation job. The fashionable-cup status also means counterfeits are everywhere, so buy direct.

**Verdict:** If you want one big cup that keeps cold drinks cold for a full round and ride in a cart, this earns its place. Walkers carrying their own bag and anyone wanting a spill-proof seal should look elsewhere, but for cart golf it is a genuinely good buy.
