The Men's Altay Zip-Off Trousers from Ayacucho are a great option for outdoor adventures that last all day. Highly versatile, durable and comfortable you'll wonder why you don't have another pair. They have a zip on each leg that sits just above the knee which you can undo to turn the trousers into shorts, the gusseted ankle zip means you can remove the bottom of the legs without taking your shoes off which is more than convenient for an outdoor environment. The fabric of the trousers is hardwearing while still comfortable and quick drying. It boasts an insect repellent finish to help reduce the number of bites and stings you get and the stain resistant finish helps you stay clean for longer. The UPF 50+ that the fabric provides helps the trousers last longer without degrading due to sunlight but also serves to protect you and your skin from harmful rays too.
