SNUG FIT BY DESIGN (size up for a regular fit)

There are those who push beyond the outer limits — and those who don't come back.

This 17th & Surf original is a homage to the golden age of sci-fi broadcasting — reimagined through the lens of deep-sea exploration. Every diver knows there are two hard limits that define the boundary between adventure and the abyss.

The Gas Density Limit hits first — the point where your breathing gas becomes so physically dense that every breath becomes labored, CO₂ builds in your system, and panic or unconsciousness can follow without warning.

Descend further and you reach the Maximum Operating Depth (MOD) — the absolute deepest you can breathe a given gas mix without risking CNS oxygen toxicity. Cross it and your central nervous system can seize.

The space between these two depths is the Outer Limits — where human physiology meets its edge. On the front, the broadcast test pattern reminds you: other forces are in control.

Beneath The Outer Limits: The Space Between Gas Density Limit and Maximum Operating Depth – 17th & Surf

This is an independent 17th & Surf parody/homage design inspired by vintage sci-fi broadcast aesthetics and deep-sea exploration. It is not affiliated with, endorsed by, or connected to any television program or its producers.

  • 75% recycled polyester, 25% elastane
  • Fabric weight: 6.64 oz./yd.² (225 g/m²)
  • Very soft four-way stretch fabric that stretches and recovers on the cross and lengthwise grains
  • Comfortable longer body and sleeves
  • Flat seam and coverstitch

Care: To make your rash guard last longer, thoroughly rinse it off after each use and get rid of any chlorine/salt residue.

Sizing: This product runs small and is quite fitted by design. If you prefer a more comfortable/relaxed fit, we suggest choosing one size up.
