40oz Tumbler XL Silicone Straw Set

The case for the brand-matched straw

There's something to be said for buying the accessory the brand actually designed for the thing. Third-party straws are a gamble: too narrow, too short, or just slightly off in a way that makes every sip feel like a small annoyance. S'well's silicone straws for the Tumbler XL sidestep that entirely — these were spec'd for the lid they're going into, which means the fit is right and the sip height is right.

At $10, they're not free, but they're not precious either. You buy them, you use them, you run them through the dishwasher, you forget you spent any money at all.

What silicone actually gets right

Silicone straws have a real edge over the two obvious alternatives. Metal straws are rigid and cold against your teeth — fine for iced coffee, less pleasant for a 40oz tumbler you're pulling from all day. Disposable plastic is what we're all trying to stop buying. Silicone sits in the middle: flexible enough to be comfortable, durable enough to outlast dozens of wash cycles, and inert enough that it won't leach anything into your drink once the brief new-silicone smell fades (and it does fade, usually within a few uses).

The multicolor set is a genuinely useful feature if more than one person in your house uses S'well tumblers. Color-coding cups is something parents figure out fast; the same logic applies here.

What we'd want you to know

These are designed for the Tumbler XL specifically. S'well makes a range of lids and vessels, and the fit isn't universal across the lineup — if you have a different S'well bottle or a different brand's tumbler, double-check compatibility before buying. The straw diameter and length are tuned for the 40oz Tumbler XL lid, and using them in the wrong lid can mean a loose fit or a straw that doesn't reach the bottom.

Silicone also requires a little more cleaning discipline than metal. The flexibility that makes it comfortable also means it can trap residue inside if you're not thorough. A thin straw cleaning brush (not always included — check the listing) makes the difference between a straw that stays clean and one that gets quietly gross. If you're already in the habit of cleaning your reusable straws, this isn't a problem. If you're not, build the habit.

The honest value take

Ten dollars for a straw set will feel like either nothing or a lot depending on your frame of reference. Compared to a sleeve of disposable plastic straws, it's expensive on a per-unit basis. Compared to a set that fails or doesn't fit, it's cheap. We think the right comparison is: you spent real money on the tumbler, the straws make it better, and $10 is a reasonable price to complete the kit. Buy them once, done.
