Smooth One-Piece PCM Cooling Neck Ring for Work and Travel

Smooth one-piece PCM neck ring for work and travel programs

SKU 1100 is a reusable PCM cooling neck ring with a smooth, continuous open-front profile. Its narrow-tube geometry is visibly different from Cryozin’s size-led plain and printed listings, giving buyers a separate format to evaluate for work, outdoor and travel accessory programs. Final fit and performance depend on the approved dimensions, PCM specification, shell construction and instructions.

Buyer facts and confirmation points

Why the smooth profile needs its own sample

A one-piece ring should be evaluated by more than a generic size label. Confirm inner circumference, front opening, tube diameter, total mass and how the ring sits on the intended wearer. Check whether the profile shifts during the intended activity and whether the finished surface, ends and filling distribution match the approved sample. These checks describe sourcing decisions; they do not establish universal comfort or safety.

Sample approval checklist

• Product drawing, inner circumference, opening, tube diameter and tolerance
• Weight, fill mass and filling distribution around the ring
• Shell/laminate identity, surface condition and end construction
• PCM grade, nominal phase specification and batch documentation
• Condition after the approved cooling/conditioning method
• Fit review for the intended user group and activity
• Damage inspection, cleaning, storage, warnings and replacement instructions
• Color, logo, label, individual pack and carton configuration

How to support a numeric PCM temperature

A numeric temperature should be tied to the exact PCM specification and product record. If the product team confirms a nominal 18°C phase-change point, describe it as a material specification rather than promising one constant wearer temperature. Any cooling-duration statement requires a defined product test with stated starting condition, ambient environment, airflow/activity and endpoint.

Material and damage claims require evidence

The exact shell material and contact requirements must be confirmed in the approved BOM and destination-market review. A general material option elsewhere on the website does not prove this SKU’s construction. Do not instruct users to continue using a punctured, leaking, deformed or otherwise damaged product without an approved safety basis and written instructions.

OEM and inspection scope

Cryozin’s customization process supports discussion of dimensions, PCM selection, shell color, logo, instructions and packaging. Feasibility and included options remain subject to project review. The material guide can organize the specification discussion but does not establish SKU 1100’s exact materials.

The approved drawing, sample, PCM record and instructions should become inspection references. Project-specific checks can cover dimensions, filling, phase behavior, sealing, appearance, print and packaging. See Cryozin’s quality-control process; exact methods, sampling frequency and documents are agreed per configuration and market.

Frequently asked sourcing questions

Is the current 18°C label verified?

The replacement page should publish it only after the exact PCM specification and relevant product verification are approved. It should be described as a nominal phase-change specification, not a guaranteed wearer temperature.

What measurements are needed?

Confirm the inner circumference, opening, tube diameter, total mass and fit range. A product drawing and physical sample are preferable to a generic S/M/L label.

Is the shell definitely TPU?

Not from the public evidence reviewed. Confirm the exact shell/laminate in the SKU 1100 BOM before publishing a material claim.

Can the ring be used after puncture?

No such claim should be made without an approved safety basis. User instructions should state how to inspect the product and what to do if it is damaged or leaks.

Which documents can be reviewed?

Documentation and testing scope are confirmed according to the exact configuration, destination market and agreed project requirements.
