Heads up — some color bleed may occur
Color bleed, especially with darker colored nylon/spandex blends, is common and could stain light colored garments if washed together.

sustainability

Groundwork Knit is made using a premium grade nylon that has a significantly tighter woven filament than standard synthetics. Tighter filaments mean less microfiber shedding in the wash-cycle, plus greater durability of the garment (longer lifespan, more wearing).

Groundwork Knit fabric is also bluesign® certified meaning it is free from harmful chemicals and is fabricated in a way that meets a high environmental standard.

A breathable essential for every runner

I recently purchased a pair of Janji running shorts (green), and I can confidently say they've become an integral part of my running gear. From their sleek design to their unparalleled performance, these shorts have exceeded my expectations in every way.

First, let's talk about comfort. The moment I slipped into these shorts, I could feel the difference. The fabric is incredibly lightweight and breathable, allowing for maximum airflow during even the most intense runs. Whether I'm pounding the pavement or hitting the trails, I never feel weighed down or restricted in these shorts.

But it's not just about comfort - these shorts are built to perform. The moisture-wicking technology is top-notch, keeping me dry and comfortable throughout my entire run. Plus, the four-way stretch material moves with my body, providing unparalleled freedom of movement and eliminating any chafing or irritation.

I also love the attention to detail in the design. The sleek silhouette and thoughtful construction make these shorts both functional and stylish. And the pockets! As someone who likes to carry my phone and keys with me on runs, the multiple pockets are an absolute game-changer. I can stash my essentials securely without feeling weighed down or encumbered.

Beyond the product itself, I'm also impressed by Janji's commitment to sustainability and social responsibility. Knowing that my purchase supports initiatives to provide clean water to communities in need adds an extra layer of satisfaction to my running experience.

With their unbeatable comfort, performance-driven design, and commitment to social and environmental responsibility, these shorts have earned a permanent spot in my running wardrobe. I can't recommend them highly enough!

Happy running!

A running essential

I set out to solve 2 problems: storage and chaffing. These shorts were the solution.

Feel great on and aren’t too revealing. Plenty of storage for race day days gels, plus, they don’t rattle around like they did in my other shorts.

Resolved my thigh chaffing issues. For me, these do chafe on occasion. There’s a thick seam which sits right on my manhood - that’s the culprit. Applying plenty of anti-chafe to the area and directly to the seam sorts it. If it wasn’t for this, I’d have said 5 stars.

Half tights

Best shorts I’ve ever owned, really comfortable and can store everything needed for marathon.

Trail Half Tights

Finally managed to order these after being out if stock for months. Well worth the wait - a quality product that is super comfortable to wear. Multiple pockets provide a range of storage options which are not available on other brands. Not the cheapest but you get what you pay for!
