## Water bottles

Which water bottles contain no plastic at all, lid included?
Page: https://amaterio.com/plastic-free/water-bottles/ (updated 2026-11-06)

November 2026, short version: four bottles make the list, all Bronze. Nothing has earned Gold or Silver yet.

The first is the soulbottles swing-top out of Berlin. Glass body, porcelain stopper, steel bail and carry handle, and a seal cut from natural rubber instead of silicone. The design on the glass is ceramic ink fired into the surface at 700 degrees, so it is not a sticker and it will not peel. What we can't confirm: the glaze on the little logo on the stopper, the gold and silver print editions, and what the shipping box is made of. We've asked. A straight answer on the glaze moves it to Silver. A paper-only box would make it Gold.

The second is Klean Kanteen's brushed Insulated TKPro 16 oz: steel bottle, steel cup, steel cap, bare brushed finish. Two silicone rings seal the cap, which is the Bronze, and the painted colors are out because the powder coat is plastic. We don't know what the logo, base cap or vacuum plug are made of, and we've asked. The maker has pulled its own page and US stock is gone; a UK shop has it.

The third is Klean Kanteen's Reflect 27 oz with the bamboo cap. Steel body, bamboo cap, no paint, and one food-grade silicone seal, which is the Bronze. We can't tell yet how the bamboo is finished, what holds it to the steel, or how the logo is marked. We've asked.

The fourth is Klean Kanteen's Rise Reflect 20 oz with the bamboo cap. Double-wall steel body, bamboo cap, no paint, and one food-grade silicone seal, which is the Bronze. We don't know how the bamboo is finished, what holds it to the steel, what the base cap and logo are, and a reviewer says the cap handle can come off. We've asked.

What didn't make it. Pura's bottle is sold as 100% plastic-free; the lid you drink from is silicone, and so are the collar and the sleeve. Primus's TrailBottle has a Tritan lid. Klean Kanteen's brushed Classic ships with a polypropylene cap. You can buy their steel cap and swap it, but then you bought a plastic cap, and we rate a bottle the way it is sold. Also out: anything powder-coated, anything with a plastic cap in use, and every bamboo lid with a plastic insert hiding under it.

In this category, plastic-free almost always means plastic-free except the silicone. We tell you which silicone, and where it sits.

### soulbottles Glass drinking bottle 0.6 l, classic-color print (swing top) [bronze]

Glass, porcelain, steel, and a seal cut from natural rubber. No silicone anywhere, which almost nothing else in this category can say. The design on the glass is ceramic ink fired into the surface at 700 degrees, so it is not a sticker and it will not peel. Three small things we can't confirm yet: the glaze on the little logo on the stopper (the maker's own blog describes a print that gets glazed and fired above 1,000 degrees, which points to ceramic, but nobody has said so outright), the gold and silver print editions, and what the shipping box is made of. We've asked soulbottles. A straight answer on the glaze moves this to Silver; a paper-only box would make it Gold.
Materials: glass (quartz sand; 60-80% recycled), porcelain, natural rubber with natural chalk (Fair Rubber), stainless steel, ceramic screen-print ink, fired on, unstated (maker blog: printed, glazed, fired above 1,000 °C), unstated. Packaging: unverified. Price seen: $29.9 on 2026-10-22.

### Klean Kanteen Insulated TKPro 16 oz (Brushed Stainless) [bronze]

A steel bottle with a steel cap and a steel cup, and nothing else we can find that you'd call plastic. The catch is the seal: two silicone rings inside the twist-and-pour cap. That's what makes it Bronze. It's the brushed finish only; every painted TKPro wears a plastic powder coat. We don't yet know what else is inside the cap, or what the logo, the base cap and the vacuum plug are made of, and we've asked Klean Kanteen. The maker's own page is gone and US sellers are sold out, so for now the live seller is Babipur in the UK.
Materials: 18/8 stainless steel, double-wall vacuum, double-wall stainless steel, stainless steel, silicone, bare brushed stainless, no coating, . Packaging: unverified. Price seen: $38.95 on 2026-11-01.

### Klean Kanteen Reflect 27 oz with Bamboo Cap [bronze]

A steel bottle with a bamboo cap and no paint on it. The one synthetic part is a food-grade silicone seal, and that's the Bronze. Klean Kanteen says it makes the bottle from just three materials, bamboo, steel and silicone, and we haven't found a fourth. What we can't pin down yet is how the bamboo is finished, what holds it to the steel, and how the logo is marked. We've asked.
Materials: 18/8 stainless steel, 90% post-consumer recycled, bamboo with a stainless steel core, food-grade silicone, none stated, . Packaging: unverified. Price seen: $32.95 on 2026-11-04.

### Klean Kanteen Rise Reflect 20 oz with Bamboo Cap [bronze]

A double-wall steel bottle with a bamboo cap, and no paint on any of it. The one synthetic part is a food-grade silicone seal in the cap, and that's the Bronze. Klean Kanteen says there's no plastic in it, and we haven't found any. Still open: how the bamboo is finished, what joins it to the steel, how the logo is marked, and what the base cap is made of. A reviewer says the handle on the cap can pull off if it gets bent. We've asked the maker.
Materials: 18/8 stainless steel, 90% post-consumer recycled, sustainably harvested bamboo, food-grade silicone, none stated, . Packaging: unverified. Price seen: $44.95 on 2026-11-06.

### Klean Kanteen Classic 27 oz (brushed) [unlisted]

Brushed 18/8 steel, no lining, no coating on the body. It ships with a polypropylene sport cap, and we rate a bottle the way it is sold. Klean Kanteen sells an all-steel cap separately, with a silicone gasket, but buying a plastic-lidded bottle and a second lid to fix it is not a plastic-free bottle. The logo on brushed bottles is powder coat, according to the company's own Q&A. If they sold the brushed Classic with the steel cap in the box, we'd list it; we've asked which of their bottles ship that way.
Materials: 18/8 stainless steel, 90% post-consumer recycled, unlined stainless steel, polypropylene with silicone gaskets, bare brushed stainless, Klean Coat powder coat (maker Q&A, undated), 18/8 stainless steel with a food-grade silicone gasket. Packaging: unverified. Price seen: $36.9 on 2026-10-22.

### Primus TrailBottle 0.6 L Stainless [unlisted]

A good steel bottle with a Tritan lid. Tritan is a plastic, the lid is what you drink through, and it ships with the bottle. The retailer we found also lists it as sold out or discontinued.
Materials: 18/8 stainless steel, Tritan, . Packaging: unverified.

### Pura Big Mouth Sport 28 oz [unlisted]

A bare 18/8 steel bottle, no paint, sold as 100% plastic-free. The sport top you drink from is silicone. So are the collar and the sleeve. Pura's care page says silicone contains no plastic. A small gasket we'd allow; a whole lid is a different animal, so this one stays off the list.
Materials: 18/8 stainless steel, platinum-cured silicone, silicone, silicone and stainless steel, bare stainless, unpainted. Packaging: unverified. Price seen: $30.49 on 2026-10-22.
