Climax Doll ULW: lightweight silicone
Full-size silicone at around 26 kg is the reason many buyers look at Climax in the first place.
Updated: October 20, 2026 · CLIMAXDOLL.ORG editorial team
Weight is the most underestimated problem with life-size dolls. A full-silicone body of 160 cm usually weighs 35 kg or more, and that number decides how often the doll gets dressed, bathed and moved. ULW (Ultra-LightWeight) is Climax Doll's answer: a weight-reduction technology used across the brand's torsos and two full-size silicone dolls.
The full-size ULW models in this guide weigh 25.7–27.1 kg and list at $1,899. For comparison, Climax's full-silicone Ultra bodies weigh 34–53 kg and start at $2,459. This page explains how ULW saves weight, what the two full-size models look like, and what you give up in exchange.
How Climax ULW reduces weight
Climax describes ULW as two changes working together.
A lighter silicone formula
The body is made from a modified elastomer with a lower density than the brand's standard silicone. The surface keeps a soft feel and realistic skin texture, so in photos and to the touch a ULW doll reads as silicone, not as a hard or hollow toy.
A re-engineered internal structure
The second change is inside: less material where it is not needed, while the outer shape, hands, feet and face keep the same detail. That is why ULW bodies keep full-size proportions rather than shrinking to save weight.
How exact the numbers are
Climax notes that its weights are averages and that individual dolls can differ by about 0.5–1 kg. Treat 25.7 and 27.1 kg as the expected range, not a guarantee to the gram.

Mayu or Rhea?
ULW SiY158 Mayu: the lightest full-size Climax
Mayu is 158 cm tall and weighs 25.7 kg, the lightest full-size doll in this guide. She has a slender build (80 cm chest, 56 cm waist, 83 cm hips), 90 cm legs, 29 cm shoulders and an East Asian face with a sleek black bob. Choose Mayu if low weight and an elegant, straight figure are the priority.
ULW SiU156 Rhea: curvier hips at almost the same weight
Rhea is 156 cm and 27.1 kg, only 1.4 kg heavier than Mayu, but her hips measure 97 cm against a 56 cm waist. She has 100 cm legs, narrow 25 cm shoulders, freckles and a long chestnut braid with western styling. Choose Rhea if you want curves without moving into the 34 kg-plus Ultra range.
What 26 kg means in practice
Lifting and bathing
At about 26 kg most adults can lift a ULW doll from a bed to a chair alone, and bathing in a shower or tub becomes a routine task rather than a two-person job. Lift by the torso and hips, not the arms, and use a towel on the tub floor so the doll cannot slip.
Delivery and the box
Both full-size ULW models ship in a 150 × 40 × 33 cm carton with a gross weight of about 34–36 kg. That is still a large box, but one person can usually bring it inside; the heaviest Ultra cartons reach 62 kg.
Storage
A lighter doll is easier to store in every position: lying flat, seated with support or hanging from a neck-support kit. The kit and rail still need to be rated for at least 26 kg. Our storage guide has the details.
What you keep and what you give up
What stays the same
ULW dolls have the full standard configuration of the Ultra line: ROS silicone head with movable jaw, EVO skeleton, shrugging shoulders, articulated fingers 3.0, standing feet, gel breasts and a simulated-scalp wig. The paid upgrades are the same too: gel butt, hard hands and feet, implanted hair, implanted brows and lashes, scratch-resistant foot screws.
What you give up
- Very full figures. A lightweight doll cannot also be a BBW body; for a 110 cm chest you need the 53 kg SiR161 Tasha from Ultra.
- Height. The full-size ULW bodies here are 156 and 158 cm; the Ultra range goes to 163 cm and the Pro hybrids to 177 cm.
- Choice. Two full-size bodies against four in Ultra and five in Pro.
Climax ULW vs Ultra vs Pro
| CLM ULW | CLM Ultra | CLM Pro | |
|---|---|---|---|
| Body | Lightweight silicone | Platinum silicone | TPE |
| Net weight in this guide | 25.7–27.1 kg | 34–53 kg | 38–45 kg |
| List price in this guide | $1,899 | $2,459–2,799 | $1,399–1,639 |
| Figures | Slim to curvy | Slim to BBW | Slim to very curvy, up to 177 cm |
| Care | No powder | No powder | Dry fully, light powder |
ULW sits between the two other lines: silicone like Ultra at a lower price, and lighter than the Pro hybrids while avoiding TPE care.
Who Climax ULW suits
- Anyone who must lift, bathe and store the doll alone.
- Buyers with back or joint concerns.
- People who want silicone but find Ultra prices too high.
- Small homes where the doll needs to be put away after each use.
