Klean Kanteen Kid Classic with Sport Cap

Recommended

Steel Kid Classic body, but the Sport Cap 3.0 kids drink through is polypropylene plus a silicone spout - so water does touch plastic at the cap.

The verdict: Minimal plastic contact

The Kid Classic bottle body is 18/8 stainless steel, but the Sport Cap 3.0 it ships with is BPA-free polypropylene (#5) with a removable soft silicone spout. The child sips from the silicone spout, but the water travels through and sits against the polypropylene cap body and valve, so plastic is in the water path. It is meaningfully less plastic than an all-plastic kids bottle (steel body, tiny plastic cap), but it is not silicone-only. Swap the Sport Cap for the all-steel Loop Cap and it becomes plastic-free (see the Classic Steel Loop Cap entry) - at the cost of the spill-resistant spout.

Lead safety: Tested lead-free

Lead Safe Mama's independent XRF testing has consistently found Klean Kanteen's non-insulated (single-wall) bottles lead-free, including paint used on the bottle exterior. This Kid Classic bottle referenced here is the single-wall version, so this finding applies to the steel body; the Sport Cap's plastic and silicone parts were not specifically covered by this testing. Klean Kanteen's separate insulated/double-wall line is not covered by this finding.

Klean Kanteen's kids single-wall steel bottle with the Sport Cap 3.0 - a flip-up soft-silicone spout on a screw-on cap, aimed at kids 3+. You flip the spout up to drink and down to close; it's spill-resistant, though not a fully sealed sport bottle. The narrow-mouth cap thread is interchangeable with Klean Kanteen's other caps, so the same body can take the all-steel Loop Cap.

Pros

  • Durable 18/8 recycled steel body; the silicone spout is replaceable
  • Spill-resistant flip spout is practical for younger kids
  • Same body accepts the all-steel Loop Cap for a plastic-free swap

Cons

  • Silicone spout needs periodic replacement
  • Single-wall (non-insulated)
