Compatibility, Size and Fit
These trousers are a men’s long-length design in size L. The half leg zip is a useful feature if you want to pull them on over footwear rather than step into a tighter leg opening. The stated 86 cm / 33 inch length is the main fit detail to check against your own requirements.
Before You Decide
Confirm the size, the 86 cm / 33 inch length and the black long-length version before choosing an offer. If you need a different leg length or a different overtrouser style, compare those details first. The stated waterproof and breathability ratings are also worth checking against how wet and active your intended use will be.
