Drop 001 runs in a focused size range. The Sports Bra and Bike Shorts come in XS–L, the Training Tee in S–XL, and our Crew Socks are one size, fitting approximately US 6–12. Each product page links to its own size guide.

Measure yourself and compare against the size guide on each product page — we publish dedicated guides for the Sports Bra, Bike Shorts and Training Tee. Sizing isn't universal across brands, so check your measurements against our chart rather than assuming your usual size. If you're between two sizes, we generally recommend sizing up for a more relaxed fit or down for a more compressive one.

Snug but not restrictive. The band should sit firm around your ribcage without digging in, and you should be able to breathe deeply and move without the bra shifting. Check the Sports Bra size guide on the product page for measurements.

Like a second skin — supportive and secure, with a high waistband that stays put through movement. They should feel firm without restricting you. See the Bike Shorts size guide for measurements.

A considered, fitted cut — close to the body without being tight. If you prefer more room, size up. The Training Tee size guide on the product page has full measurements.

Yes. We can deliver to PO Boxes and Australia Post parcel lockers within Australia. Just enter the address at checkout as normal.

You have 14 days from receiving your order to return eligible items. Items must be unworn, unwashed and in original condition with tags attached. You'll need proof of purchase (order confirmation email or receipt). Sale items are final sale and cannot be returned. Socks can only be returned if they are in their original, unopened packaging. If we receive your return between 15 and 30 days after delivery, a refund is not available but we can offer an exchange or store credit.

Email us at admin@headnoisephilosophy.com with your order number and the item and size you'd like to exchange for. We'll confirm availability and guide you through the process. Once we receive your returned item and confirm it meets our eligibility criteria, we'll dispatch the replacement. If the exchange item is of higher value, you'll need to pay the difference. If it's of lower value, we'll issue the balance as store credit.

Because Drop 001 is a limited release, we can't guarantee stock will be available for your exchange. If your preferred item or size is out of stock when we process your return, we'll contact you and offer a full refund to your original payment method or store credit instead.

Only if they are in their original, unopened packaging. Once opened, socks cannot be returned or exchanged for change of mind. This doesn't affect your rights under the Australian Consumer Law if an item is faulty.

No. Sale items are final sale and cannot be returned, exchanged or refunded.

Email us at admin@headnoisephilosophy.com within 14 days of receiving your order. You'll need your proof of purchase (order confirmation email or receipt). Items must be unworn, unwashed and in original condition with tags attached. We'll guide you through the process from there.

Return shipping is your responsibility unless the item is faulty or we sent the wrong item — in those cases, we cover it. We recommend using a shipping service with tracking to ensure safe delivery to our returns facility.

Contact us at admin@headnoisephilosophy.com as soon as possible with photos of the fault. Please do not return faulty items before contacting us first. We'll sort out a repair, replacement or refund. Your rights under the Australian Consumer Law always apply.

Because Drop 001 is a limited release, we can't guarantee an exchange — stock may sell out. The fastest way to get the size you want is to place a new order and return the original within 14 days, unworn with tags and proof of purchase. Email admin@headnoisephilosophy.com and we'll help.

If we receive your return between 15 and 30 days after delivery, we cannot offer a refund. However, we can offer an exchange for another item of equal or lesser value (subject to availability) or store credit for the original purchase amount. Returns received after 30 days cannot be accepted.

Fabric composition is listed on each product page under the Materials tab. Every piece is designed in Australia and made with care in China.

Care instructions are on each product page under the Care Guide tab and on the garment's care label. As a general rule: wash cold, inside out, on a gentle cycle with similar fabrics. Skip fabric softener — it breaks down technical fibres — and air dry out of direct sun.

Designed in Australia, made with care in China by our manufacturing partner.

Our fabrics are selected for comfort against the skin during high-movement, high-sweat activities. The Sports Bra and Bike Shorts use a nylon-spandex blend; the Training Tee uses a polyester-spandex performance mesh; and the Crew Socks are cotton-rich. Full fabric compositions are listed on each product page under the Materials tab. If you have a known sensitivity to any specific fibre, we recommend checking the composition before purchasing.

We stand behind the quality of every Headnoise product. If a product develops a manufacturing defect under normal use and care, contact us at admin@headnoisephilosophy.com with photos and your proof of purchase and we'll make it right. This is separate from our change-of-mind returns policy and your rights under the Australian Consumer Law always apply.

Under Australian Consumer Law, products come with consumer guarantees that cannot be excluded. You are entitled to a repair, replacement or refund if a product has a major fault, is not of acceptable quality, doesn't match its description, or doesn't do what we said it would. Minor faults must be repaired in a reasonable time. These rights apply regardless of our returns policy and cannot be overridden by any store policy. For more information, visit accc.gov.au.

Headnoise releases in limited drops rather than open-ended seasonal ranges. Drop 001 is our first release — a tight edit of five pieces, made in limited quantities.

We can't guarantee it. Drops are made in limited quantities and, once a size or piece sells out, it may not return. If you want it, don't wait.

Sign up on our homepage to join the mailing list. You'll be first to know about new drops, restocks and what's next.

Once an order has been placed it cannot be amended or cancelled. We strongly recommend checking all details — size, colour, delivery address and shipping method — before completing checkout. If your order arrives and isn't right, you can start a return once it's delivered.
