soulbottles Glass Bottle (ceramic swing-top)
A German-made glass bottle that closes with a ceramic stopper and a natural-rubber gasket on a stainless-steel swing-top - no plastic and no silicone anywhere the water touches, and leak-proof even with carbonated water.
The verdict: Plastic-free
One of the rare water bottles that is genuinely plastic-free: the body is glass, the swing-top stopper is glazed ceramic, and the seal is a natural- rubber (not silicone) O-ring, clamped shut by a stainless-steel bail. Every surface the water contacts is glass, ceramic, or natural rubber - no plastic and no silicone. The bottle ships this way (no separate cap to buy), and the swing-top holds a seal even under carbonation.

What it's made of
| Part | Material | Food contact |
|---|---|---|
| bottle body glass with recycled content; brand does not market it as borosilicate, so treat it as ordinary glass (avoid thermal shock) | Soda-Lime Glass | Yes primary |
| swing-top stopper glazed ceramic disc that seats over the mouth | Ceramic / Stoneware / Porcelain | Yes primary |
| gasket / seal natural-rubber O-ring (not silicone) - what keeps this plastic-free rather than silicone-only; sold separately as a replacement | Natural Rubber / Latex | Yes seal |
| swing-top bail / lever stainless-steel clamp that holds the stopper down; exterior, does not touch the water; grade unspecified | Stainless Steel grade unspecified | No |
soulbottles' signature glass bottle uses an old-fashioned swing-top (bail) closure rather than a screw cap - a ceramic stopper pressed onto the mouth by a stainless-steel lever. It seals well enough for carbonated drinks and is dishwasher safe, and every wear part is sold on its own for repair. It comes in 600ml and 1000ml. The trade-off versus a screw-cap steel bottle is the fiddlier bail mechanism, ordinary (non-borosilicate) glass that dislikes thermal shock, and no insulation.
Pros
- Genuinely plastic-free AND silicone-free in the water path - glass, ceramic, natural rubber
- Ships ready to use - no separate steel cap to buy, unlike the steel bottles
- Leak-proof even with carbonated water; dishwasher safe
- Replacement stopper and rubber gasket sold separately, so it is repairable
- Made in Germany by a plastic-free-focused brand that funds clean-water projects
Cons
- Ordinary glass, so heavier and more breakable than steel - and not for boiling water / thermal shock
- Swing-top bail is more moving parts than a plain screw cap
- Not insulated; open-mouth drinking (no straw or spout)
- Natural rubber is a wear part and can perish over years (replaceable)
Notes
- There is also a stainless-steel soulbottle line; this entry is the glass one
