Prepare for your fall trail running adventure with the senja collection. Each piece is meticulously designed to ensure your comfort and performance as you conquer the trails in style.

As the summer heat mellows into the crisp embrace of fall, trail runners around the world gear up for a new adventure. The changing leaves, cooler temperatures, and invigorating air make autumn an ideal season for hitting the trails. However, as any seasoned runner knows, proper gear and layering are essential to conquer the unpredictable weather that comes with the fall season. Enter the senja collection – Specialized gear for trail running for all season use and any weather. Lightweight, packable, weather protective with excellent moisture management. In this guide, we'll dive into the art of layering using the senja collection, ensuring that you're prepared to tackle any trail, any weather, and any challenge that comes your way.


Base Layer

Every successful layering strategy begins with a solid base, and in this case, it's the senja equaliser lightweight Long sleeve. Crafted from a blend of merino wool and polyester, this shirt offers exceptional moisture-wicking properties, effectively keeping sweat away from your skin while providing natural odor resistance. The lightweight and breathable design ensures you stay comfortable and dry, no matter how intense your run gets. Plus, the fabric's natural temperature-regulating abilities make it a great choice for those chilly autumn mornings that can quickly turn into warmer afternoons.

Mid Layer

When it comes to the mid layer, the senja warm1 Hood stands out as a versatile choice. Crafted with our innovative Warm™1 fleece fabric, this hoodie offers exceptional warmth-to-weight ratio and efficient moisture management. Its snug hood adds an extra layer of protection, and the front zipper allows for easy ventilation during intense runs. The senja warm1 Hood's sleek design ensures unrestrained movement, making it an ideal mid layer to keep you warm and comfortable during your fall trail adventures.

Outer Layer

The crown jewel of your fall trail running ensemble is undoubtedly the senja Gore-Tex Active Jacket. Engineered with a waterproof and windproof Gore-Tex membrane, this jacket will keep you dry no matter the conditions. Rain, wind, and even snow – the senja Gore-Tex Active Jacket is up to the challenge. As protective as it is, breathability remains a key element in the jackets design, preventing overheating and ensuring your comfort throughout your run. The adjustable hood, cuffs, and hem let you tailor the jacket's fit to your liking, while reflective details enhance visibility during low-light conditions.

Don't neglect your lower half when perfecting your layering game. The senja equaliser stretch Tights are a fantastic choice to keep your legs warm and protected. These tights are crafted with the same merino wool blend as the base layer, offering moisture-wicking properties and natural odor resistance. The snug fit and flatlock seams prevent chafing and discomfort, allowing you to fully focus on going further.
