Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

What is the 150 Siren Bra?

The 150 Siren Bra is a lightweight, low-support bra designed with a modern fit for optimal comfort and versatility. Crafted from merino core-spun fabric, it regulates body temperature, wicks moisture, and resists odours, keeping you comfortable in all weather conditions.

What are its features?

This bra is built with thoughtful design elements to ensure comfort, flexibility, and functionality, whether you're lounging, travelling, or engaging in light activities.

Features:

  • Merino Corespun Fabric: Combines merino wool with nylon and elastane for durability, temperature regulation, and stretch.
  • Flatlock Seams: Minimise friction for next-to-skin comfort.
  • Low Support: Ideal for light activities and everyday wear.
  • Adjustable Straps: Allow for a personalised fit.
  • Removable Cups: Offer versatility for shaping and coverage.
Technical Information

Technical Specification:

  • Fabric: Merino Jersey Corespun (83% Merino Wool, 12% Nylon, 5% Elastane).
  • Fibre Micron: 9µ for a soft and smooth feel.
Sizing Information

Measurements refer to body size, not garment dimensions. In instances when your body measurements are midway between two sizes, go to the smaller size for a tighter fit or the larger size for a looser fit.

If your body measurements result in different sizes, we recommend using your chest measurement for tops and your hip measurement for pants.
