Klean Kanteen Reflect 27 oz Water Bottle with Bamboo Cap, Brushed Stainless

1. What touches your drink 45% of the rating 5 of 5

   Your drink and mouth touch steel; the cap is steel with a bamboo top and a silicone gasket, and the maker lists no paint, ink, coating or plastic.

2. Independent testing 20% of the rating 4 of 5

   Lead Safe Mama's X-ray (XRF) checks find Klean Kanteen's non-insulated bottles lead-free, but it publishes no result for this model or its bamboo cap, and we found no lab leach test.

3. Durability 15% of the rating 5 of 5

   A lifetime limited warranty against defects for the original buyer, a single-wall body with no vacuum to lose, and gaskets and caps sold separately, though buyers report the thin steel dents.

4. Trust 10% of the rating 3 of 5

   It names the steel grade, gasket and country of manufacture and answers the lead question in its FAQ, but it had a 2010 recall of a different part and Lead Safe Mama's owner calls its lead-free advertising misleading for its older insulated bottles; no Prop 65 notice.

5. Value 10% of the rating 3 of 5

   $32.95 for 27 oz is about $1.22 an ounce, well above the 40 oz Wide at about $0.80 an ounce.

• Independent Lead Safe Mama, LLC (independent advocate; earns Amazon affiliate income) February 2026

  Its February 2026 water bottle list says XRF tests of countless Klean Kanteen non-insulated bottles found them lead-free in all components, and it recommends only that kind from the brand. It publishes no result for the Reflect itself. Open ↗ (opens in a new tab)

• Independent Lead Safe Mama, LLC (independent advocate; earns Amazon affiliate income) January 2024

  Its guide, updated January 2024, says Klean Kanteen's non-insulated adult and children's bottles tested consistently lead-free and that the paint on them is lead-free. It does not recommend the brand's insulated bottles because it has not confirmed them. Open ↗ (opens in a new tab)

• Independent Mamavation (a desk review of 180+ bottles from public information, not a lab test; earns affiliate income) April 2025

Is anything on it plastic or painted?

The maker's product page (opens in a new tab) says it is made from three materials, bamboo, stainless steel and food-grade silicone, with no paint, ink, coatings or plastic. The Bamboo Cap is steel inside with a bamboo top, and the cap should be washed by hand. We could not check these claims independently.

Can a made-in-China steel bottle carry lead?

Lead has turned up in the vacuum sealing dot of other brands' insulated bottles (Lead Safe Mama (opens in a new tab)). This bottle is single wall, so it has no such dot, and Lead Safe Mama's X-ray tests found the brand's non-insulated bottles and their paint lead-free (2026 list (opens in a new tab)). The maker says all its products are lead-free and that its insulated bottles use glass plugs instead of lead (FAQ (opens in a new tab)). Lead Safe Mama's owner replied on that list in April 2024 that the brand's insulated bottles had lead through 2017, that she has not tested a new one, and that she finds the brand's lead-free advertising misleading about the older bottles. Her tests of the single-wall bottles are the ones that apply here.

Do the steel-on-steel threads shed metal?

A reader on Lead Safe Mama's site quoted a two-star Amazon review saying the steel-on-steel threads grind when tightened and leave steel dust inside the lip (comment, December 2023 (opens in a new tab)). On the maker's product page (opens in a new tab) one 2019 buyer reports black residue from the threads and several say the cap squeaks, though the page rates it 4.7 of 5 from 428 reviews. We found no test of what comes off.

Does stainless steel leach nickel into water?

Little does into plain water. Our water bottle guide found low metal release in lab tests, while acid raises it: a 2026 case report (opens in a new tab) tied a systemic nickel skin reaction to a steel bottle holding a citric acid solution. The maker says not to put hot or carbonated drinks in this single-wall bottle, and Lead Safe Mama advises steel bottles for water only, rinsed daily.

Has Klean Kanteen had a recall or a lawsuit?

CPSC lists one recall, in 2010, for the plastic spout of a Sport Cap bottle (CPSC (opens in a new tab)). No Prop 65 notice names the company (California AG search (opens in a new tab)), and a web search found no class action over its bottles. None of this concerns this bottle.

Is the silicone gasket a worry?

Lead Safe Mama reports that silicone parts often show trace cadmium in X-ray tests, typically 10 to 30 ppm (guide (opens in a new tab)). We found no test of this gasket, which seals the cap and touches the water only while the cap is on.

Is the Amazon or Walmart seller the maker, and does the warranty still apply?

No. Pattern Professional on Amazon and Pattern on Walmart are third-party sellers. The lifetime warranty covers purchases from Klean Kanteen or authorized sellers, and its warranty page (opens in a new tab) names only Pattern's "Pattern Direct" Amazon storefront (merchant ID A3896QKF2DOVE4) and Walmart itself ("sold and shipped by Walmart.com"). The Amazon listing's seller link carries a different ID (A2O5KH22APDXN1) and the Walmart one is sold by Pattern, so we could not confirm either is covered. Buying from the maker avoids the question.

• The drink touches steel and a silicone gasket: the maker lists bamboo, 18/8 stainless steel and food-grade silicone, and no paint, ink, coating or plastic.
• It has no vacuum seal to hide lead in, and Lead Safe Mama's X-ray checks find the brand's non-insulated bottles consistently lead-free.
• It can be repaired: a lifetime limited warranty, with replacement gaskets (about $8 for a kit) and caps sold separately.

• Not insulated, so it will not keep drinks cold or hot; the maker says not to put hot or carbonated drinks in it.
• The bamboo cap should be washed by hand, and the bamboo's finish is not named.
• Buyers on the maker's page report that the thin steel dents when dropped and then wobbles on a flat surface.
• No independent test of this exact model is published, and the steel grade is the maker's word with no mill certificate.
• About $1.22 an ounce; the Wide 40 oz and the painted Classic bottles cost less per ounce.
• Lead Safe Mama advises using steel bottles for water, not coffee, tea or juice.
