Fabric & Fit: materials and cuts

Three fabrics and three fits: what each one is made of, how it behaves and what it is for.

Three fabrics, three jobs

Most of the line is built on three fabrics. Each one was chosen for a single job and tested until it did that job after 50 washes. When you know which fabric a piece is made from, you know how it will feel, stretch and wash.

A few pieces use a named cotton jersey, a merino blend or a stretch canvas where those do the job better. Their product pages list the composition and weight in the same way.

AirKnit

A light, open knit for hot sessions. The fine perforations let air through and the elastane keeps tees and tanks from sagging when they are wet.

Three fits

Fit describes ease: the space between your body and the garment. All figures are for size M. Each product page lists its own measurements under Fit & feel.

Compression-1.5 in / -4 cm26 in / 66 cmClose to the skin, held firm by the fabricLeggings, sports bras, base layers

Relaxed

Cut with a lowered shoulder seam and a straighter body. It layers easily over a base layer and is the fit we use for TerraFleece hoodies and joggers.

Regular

The default for most tops and shorts. Enough room to move through a full range of motion, close enough that nothing catches on a bar or bench.

Compression

A close fit with negative ease, so the fabric sits flat against the skin and does not shift. Compression here is a fit, not a promise: we make no claims about what it does for your body.

How to choose

Hot, fast sessions

AirKnit in a Regular fit. Light, dry and quick to air out between sets.

Lifting and mobility

CoreFlex in Compression or Regular. It stretches with you and goes back to shape.

Before and after

TerraFleece in a Relaxed fit. Warm on the way in, easy on the way home.
