The55 T-shirt — “Stronger Than Ever”
The55 T-shirt — “Stronger Than Ever”
A lightweight cotton The 55 Branded crew tee with a quiet, confident design — a small, mint-green chest line reading “Stronger Than Ever” and a bold, circular mint emblem on the back. The classic crew neckline and neat fit let the message sit subtly in everyday settings: layered under a jacket for city commutes, worn solo on warm afternoons, or tucked into high-waisted jeans for a clean, modern look. Feels breathable and easy to move in; the text and back graphic read like a personal reminder carried with you through long days, workouts, and quiet wins. Crafted for durability with shoulder tape and side seams so it keeps its shape wash after wash. For people who prefer understated statements and mindful style, this tee blends simplicity with a strong visual identity.

The55 fitness sandbag FAQs.
The pre-filled sandbag holds a maximum weight of 25kg. But, you can adjust it whenever you workout by removing inserts. It just takes seconds.
Perfect for all fitness levels, as you can adjust the weighted bag and the intensity of your workout. We recommend beginners to start with lighter weights (or check out our unfilled multi-weight bag to fill it with whatever you have to hand), and gradually increase as you build strength. If you want to go intense, keep loading up the weight.
Yes, it’s already fully loaded up with 4 x 5kg inserts – we’ve done it all for you. All that’s left for you to do i you can adjust your workout in seconds (just unzip and you’re good to go) and all in one place.
We might be here a while. OK, strap in: squats, deadlifts, swings, pulls, pushes, burpees, walking, sprinting… we know the possibilities can feel infinite, which is why we’ve got handy workouts over on our blog. Or follow us on socials for live workouts with our favourite PTs.
Yes, we do.
It really depends on your ability and how custom you want the weight to be. To workout with lighter weights, you might prefer our unfilled bag to load it up with whatever you have to hand. For an all-in-one, ready-to-roll solution – our signature pre-filled sandbag gives you added weight of up to 20kg (in increments of 5kg, 10kg, 15kg, 20kg).
We don’t call it an all-in-one for nothing. Whatever your fitness goal—toning, strengthening, or muscle-building—our sandbag was designed to give you a full-body workout. It’s a gym in a bag.
