Made To Measure Powerstretch Undersuits

Powerstretch fleece is easy to move in, quick draining and very warm for it's weight. Now available in two different weights. The lightweight option is suited to warmer caves. The heavier weight option is suited to very cold caves but it still light compared to other fleeces.


Stretchy undersuit available in two weights. Reinforced knees, elbows and seat, plus a high neck to seal in warmth when required. Exterior pocket on wearer's right side to avoid clashing with oversuit pocket. Robust 2 way YKK zip. Warmer than most suits because it fits, avoiding air pockets which fill with circulating cool air. Works best with a tight fit.


Polarfleece colours available

Left to right: Sky blue (lightweight fleece only) and grey (heavier weight fleece only).



Extended crotch zip that goes round to the back and is useful for females. Pocketed knee pads allowing you to insert your own pads that will stay in place. Mix'n'match fleece colours.

Heavier weight undersuit £95

JumpSuits are proud to employ their own tame ‘Field Test Engineer’ who has sneaked into the header above! His job is to attempt to test our suits to destruction. Known simply as ‘The Dig’, some say he spends his life underground, feeding intravenously, digging forever on downwards...

Product Review: "I have used the Powerstretch lightweight undersuit for 5 months now and cannot fault it. The workmanship and design is excellent and it fits ideally. I have used it for both sports caving and digging and it has kept me nicely warm throughout."
