A FEW NOTES
- Filling past the 300ml mark and/or leaving the drinking spout open may damage the spout as liquids expand when frozen
- Do not freeze carbonated drinks
- Yes, this is an off-the-shelf bottle. This is our first scrappy test; a proprietary bottle is next.
We designed this bra with a meshed front bridge and back panel for maximum airflow, and a unique back hydration compartment for active cooling. We stripped hydration vests down to the absolute essentials.
- Buttery-soft fabric flatlock seams throughout the bra to minimize discomfort and chafing
- Thin removable cup pads for breathability and airflow, and for ease of cleaning
- Stretched underbust band for light running support
- Stretched power mesh pocket on the back to minimize bounce
- Small pull tab for easy bottle access
- Medium support bra, generally suited for runners with A to C cups
