Why PETG, Not PLA?
We use PETG for all Whoop Adapters because it offers the perfect balance of strength, flexibility, and durability — essential for daily wear and secure fit.
Unlike PLA, which can become brittle and warp under heat or stress, PETG is:
More impact-resistant
Better suited for handling tension and repeated use
Less likely to deform in warm environments (like against your skin or in the sun)
Our priority is to ensure your adapter stays reliable, safe, and long-lasting — and PETG delivers exactly that.
