Yes. All Astra Straps bands use use precision-machined stainless steel connectors that lock securely into your Apple Watch — the same mechanism Apple uses. They won't scratch your watch or interfere with sensors like heart rate or blood oxygen. All our materials are skin-safe and nickel-free, and using a third-party band does not void your Apple Watch warranty.

We get it – sometimes things just don’t work out. If you’re not in love within 100 days, send it back, no questions asked. We’ll refund you, no drama. We want you to have a band you absolutely love.

We’re all about speed. Most orders ship within 1-2 days, and you can expect it to arrive shortly after.

Plus, if you spend over $50, shipping is on us. Because let’s be real, no one wants to pay extra for shipping.

Great question! At Astra Straps, we don’t just make bands – we craft them.

Every single band is hand-finished to ensure the highest quality and attention to detail. We’re all about combining top-notch materials with unique designs that reflect your personal style.

Plus, we test every band for comfort and durability, so you can count on a strap that’s as strong as it is stylish. When you choose Astra Straps, you’re not just getting a band – you’re getting a piece of wearable art.

Since the Infra is a one-piece loop with no clasp, getting the right size matters. It comes in three sizes per wrist size — Small, Medium, and Large — each covering a narrow range (roughly an inch) for a more precise fit. Measure your wrist with a flexible tape measure and match it to the size chart. A snug-but-comfortable fit is what you're after — it should stay in place without leaving marks.

Yes — the Infra is made from medical-grade silicone, which is the same type of material used in healthcare products. It's hypoallergenic, free from irritating chemicals, and designed to sit comfortably against your skin all day. If you've had reactions to metal clasps or cheaper silicone bands in the past, this one's a solid alternative.

The Infra is engineered to hold its shape — the medical-grade silicone is flexible enough to slide on easily but firm enough to maintain a consistent fit over time. Unlike some solo loop styles that loosen after a few months, the three-size system means you're not relying on stretch to get the right fit in the first place.

It's one of the best options for active use. The seamless design means there are no buckles or clasps to dig in or bounce around, and the lightweight, sweat-resistant silicone stays comfortable through long runs and intense sessions. It's also water-resistant, so you don't need to worry about rain or sweat buildup. Just slip it on and go.
