From Trimtex:
These Basic long orienteering pants for both women and men are comfortable and very airy that are fitted, but with a loose fit. The orienteering pants are made from a strong polyester fabric that is very durable, airy and light, making them highly suitable for tough runs in the woods. The low weight makes the O-pants feel light on the body. The pants have an elastic waistband with a drawstring, and a front pocket with a Velcro fastening.
This product has a regular fit. This means that it has a looser fit on the body, it is not supposed to be tight or restrictive.
