Gear built to be trusted at 13,000 feet.
Sirius Design is a one-shop studio: the AERIS altimeter line for skydivers, and 3D-printed goods finished in-house.
Altitude, descent rate, at a glance.
A wrist-mounted altimeter built for freefall: read it in a half-second glance, glove on. Enclosure is 3D-printed and finished in Santa Barbara.
- AMOLED display, high refresh rate — smooth, vivid readouts in direct sun or shade.
- Water-resistant housing — built to handle sweat, rain, and rough weather ops.
- High-accuracy sensor — tight, reliable altitude and descent-rate readings.
- Comes standard with a velcro wrist strap — adjustable, easy on/off over a jumpsuit.
- Long-lasting battery — charge it before the day, not between jumps.
Skydiving gear carries real risk — AERIS is a secondary altitude-awareness aid, not a replacement for training or judgment. Read the full safety warning before use.
3D-printed goods, made to order.
Every enclosure and print ships from the same bench where AERIS is built — tight tolerances, real finishing, no shortcuts.
