Care Guide
Your STÆRKE Mini In-Gym Bag is designed to be strong, functional, and long-lasting. With just a little care, it will stay looking fresh and ready for every session.
Daily Care
Wipe clean with a damp cloth after use, especially if exposed to chalk, sweat, or gym floors. Allow the bag to air dry naturally — avoid sealing it away when damp.
Washing
If needed, hand wash gently in lukewarm water with mild soap. Do not machine wash, bleach, or tumble dry — this may damage the recycled nylon's structure and waterproof coating.
Storage
Avoid long exposure to direct sunlight when not in use, as UV rays can fade the colour over time. Keep sharp objects away from the fabric to prevent unnecessary snags.
Sustainability Note
Our bag is made from recycled, waterproof 290T twill nylon — built to last while keeping waste out of landfills. The better you care for it, the longer it will serve you, and the lighter your footprint will be.

I built STÆRKE because nothing else existed
After six years of training, I kept running into the same problem. Everything I needed mid-session ended up scattered on the gym floor or carried awkwardly between machines. I looked everywhere for a bag designed for inside the gym. Nothing existed. So I built it myself.

Frequently asked questions
How big is it?
The Mini measures 24 × 19 × 15 cm. Compact enough to sit beside you on the gym floor without getting in the way, but spacious enough for your phone, keys, water bottle, ankle straps, resistance band, headphones, and a few extras. Most customers are surprised by how much it holds. If you're unsure, the pack-my-gym-bag video above shows exactly what fits.
What is it made from & how do I clean it?
The Mini is made from recycled, waterproof 290T twill nylon inside and out, with metal hardware and protective bag feet. To clean your Mini, simply wipe down with a damp cloth after use. For a deeper clean, hand wash gently with mild soap and lukewarm water. Do not machine wash or tumble dry as this can affect the waterproof coating.
Can I return it?
The Mini comes with a 14-day return policy. Every bag is quality-checked before it leaves us, but if anything isn't right we'll, of course, make it right.
