This page showcases CLM (Climax Doll) ULW (Ultra-Lightweight) full-size silicone sex dolls, currently featuring the ULW SiY 158cm and ULW SiU 156cm models, with more full-size body styles to be released continuously in the future.

Powered by CLM’s industry-leading ULW (Ultra-Lightweight) technology, these full-size silicone dolls achieve significant weight reduction while preserving exceptional softness, elasticity, and structural integrity.

Unlike conventional lightweight designs, ULW technology maintains a seamless silicone surface with no detectable lightweight filler feel—only a natural, human-like “flesh” touch that feels soft, dense, and realistic to the hand. The reduced weight makes the doll easier to lift, carry, and reposition around the home, while still delivering a deeply immersive, true full-size experience.
FAQ-ULW Sex Doll

Yes, it is possible, but it falls under custom orders. Creating other doll styles with ULW technology requires redesigning the internal structure and developing new molds, which may incur additional costs. Please contact customer service before purchase to discuss feasibility and customization options.

Currently, ULW (Ultra Lightweight) structures are not compatible with TPE. TPE requires high-temperature molding, which can melt the internal PU foam and damage the structure. Silicone is preferred for ULW dolls, as it reduces weight while maintaining strength and safety.

No. ULW design only optimizes internal filling and material structure. The skeleton itself remains fully functional, with the same joint strength and load-bearing standards as standard dolls. Weight reduction does not compromise structural stability or durability.

With proper care and maintenance, a ULW sex doll can last for several years. The lifespan depends on usage frequency, cleaning habits, and storage conditions. We recommend following the care guide, using mild soap for cleaning, and storing the doll in a cool, dry place to maximize its longevity.

Yes, the ULW sex doll is designed for easy cleaning and maintenance. You can clean it with warm water and mild soap after each use, then pat dry with a soft towel. Regular powdering with cornstarch or baby powder helps maintain the skin texture. Avoid harsh chemicals, direct sunlight, and extreme temperatures to keep the doll in optimal condition.
