Alpinestars Bogota Pro Drystar 4-Seasons Motorcycle Trousers CE AA with Protectors Waterproof

Alpinestars Bogota Pro Drystar – Four-season trousers for true adventurers

Are you wondering whether motorcycle trousers can really last all year round – in rain and heat alike? The Alpinestars Bogota Pro Drystar 4-Seasons answers this question with a resounding yes. These trousers were developed specifically for riders who don't want to change their gear according to the seasons. Whether on long motorway journeys in autumn or commuting in the rain, the Bogota Pro has earned its place in the motorcycle wardrobe of any true biker. The intelligent Drystar® lining system keeps your trousers dry, while the large ventilation panels won't let you down even on muggy summer days.

The 5 most important features at a glance

What sets the Alpinestars Bogota Pro Drystar apart in practice

The Bogota Pro shows its true strength on long tours, especially when the journey takes you through different seasons. The Drystar® system works on a clever principle: you can wear the waterproof inner lining under or over the outer trousers – depending on what the situation requires. In midsummer? Take out the lining and just wear the outer layer as a light windbreaker. When it suddenly starts to rain? Quickly take out the lining and you have complete rain protection – without the trousers becoming uncomfortable. It is precisely this flexibility that makes the difference between theory and everyday life. The wide ventilation panels on the thighs serve a real purpose. In stop-and-go traffic or when riding slowly through the city, heat and humidity can quickly build up. With one-handed operation – did you notice that you don't have to take your foot off the throttle? – the panels can be opened quickly. After 300 kilometres on the motorway in summer, you'll be grateful for this detail. At the same time, when closed, these panels still offer wind protection and contribute to your safety. The integrated Nucleon Flex Pro knee protectors not only serve a purpose – they are Level 2 certified, which means they offer significantly more impact protection than older standards. The Bio-Flex hip protectors complement the system perfectly. Anyone who has ever fallen knows that the hips often bear a heavy load in the event of an impact. Alpinestars has not skimped here.

I know from experience that motorcycle trousers that can really cope with all seasons often come at a high price – or they don't work optimally. The Bogota Pro strikes a clever balance here: it doesn't cost three times as much as summer trousers, but offers features that are otherwise only found in specialised all-season models. The price-performance ratio here is really solid.
