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’m so happy for my long strap - very easy to attach and in the same high quality as the MINI. It completes my MINI.
Hi Hanne, I’m so glad the long strap fits all the essentials and that you’re happy with its quality. It’s great to hear it completes your Mini! x
Perfect!!
Love my long strap for my bag!
I use this strap all the time and the bag is so versatile. It’s my go to bag for running around running errands and also love using it when im on a dog walk. Can’t recommend it enough and it all fits so much including folded up tote bag for a last minute grocery shop! Super sturdy 🫶
Hi Alona! We're thrilled to hear you're loving the long strap and how versatile it is. Thanks so much for sharing your experience xx
As soon as the strap was released I knew I needed it! It means I can carry the bag across body to and from the gym, office and shops. I bought both colours and love switching them out depending on what i’m wearing that day!!
