Polaris LS Pro undershorts



Work well with baggy shorts or 3/4s, but pricey and a tad sweaty

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

Perfect beneath ¾ courier knickers or mtb baggy shorts, Polaris LS pro liners are a considerable improvement over most OEM inserts thanks to superb cut and good quality pad but the polyester based fabric induced feelings of damp faster than more sophisticated materials.

Cut marginally longer in the thigh than most, the Pro undershorts provide unrestricted movement while the tactile Silicon grippers and elasticated waist keep them perfectly positioned despite sustained effort and look much shaper beneath unlined Lycra training tights. The thin, perforated panels are quite revealing but just modest enough to be worn sans shorts in a pinch and a real boon for indoor training in the privacy of garage or living room.

However, the polyester derived Airbase fabric lacks the wicking prowess of more expensive fibres. Mercifully, the medium density Coolmax pad employs silver technology-a clever anti bacterial that combats odour. Pad density was spot on, providing just the right levels of support and insulation from road and trail shock while not sticking out like the proverbial sore thumb underneath civvies.

Undeniably competent, comfortable undershorts complementing both the cycling and civilian wardrobes, they're a little pricey for polyester derived materials. Only superb cut and rapid drying times present any notable advantage over cheaper rivals.


Ideal beneath ¾ courier knickers or mtb baggy shorts but pricey given they're polyester based.

Tell us how the product performed overall when used for its designed purpose

Extremely comfortable thanks to generous length, padding strikes an equally impressive balance between density and comfort. They're probably the best I've used beneath 3/4 knickers but felt damp around the crotch sooner than expected.
