- Sport-Tek performance fleece quarter-zips for cold-protocol mornings.

- No minimum, US-printed in about a week.
Biohacking community quarter-zip pullovers are the right cold-day layer for protocol-heavy mornings: cold plunge sessions, sauna-cold-contrast cycles, outdoor cold-exposure walks, and dawn breathwork practices. The half-zip lets the wearer ventilate during warm-up and seal up for cold transitions. Pro Shops carries the Sport-Tek performance quarter-zip with no minimum and community-brand printing on the chest.
Why a Quarter-Zip Beats a Hoodie for Cold Protocols
Cold-plunge and sauna-contrast protocols involve repeated layer-on, layer-off transitions. A pullover hoodie has to come off over the head every time, which is awkward right after a 38-degree plunge with cold hands. A quarter-zip unzips at the neck, vents, and stays on the body during the transitions. For protocols that involve standing outside in cold air between plunges or sauna rounds, the half-zip neck adjustment matters.
For pure warmup or post-protocol bench wear, the hoodie still wins on comfort. The quarter-zip is the protocol-day-specific layer.

Quarter-Zip Design Direction
- Community logo on the chest. 3 to 3.5 inches wide. Quarter-zip chest area is smaller than a hoodie chest, so size the logo down accordingly.
- Optional sleeve hit. Small text or symbol on the sleeve cuff.
- Back-only design. Blank front, a larger graphic or wordmark on the back. Works for communities with a strong back-of-shirt design language.
- Color: charcoal, navy, forest, oat, black. Same dignified-neutral palette as the rest of the community apparel.
Quarter-Zip Revenue Within a Community Store
Quarter-zips typically run 10 to 15 percent of the warmup category in a community store, behind hoodies (50-55%) and crewnecks (20-25%). Per-item margin runs $14 to $18 on Sport-Tek quarter-zips. For a 2,000-member community, quarter-zip sales typically add $400 to $700 of annual revenue on top of the hoodie line, with cold-climate communities clearing the high end of the range.

Start FreeFrequently Asked Questions
Why would a biohacker community member buy a quarter-zip over a hoodie?
Protocol-day practicality. Cold-plunge and sauna-contrast routines involve repeated layer transitions; the half-zip neck adjustment is easier than pulling a hoodie over the head with cold hands.
What is the difference between a Sport-Tek quarter-zip and a hoodie fabric-wise?
Quarter-zips run a lighter performance fleece (designed to ventilate during warmup), hoodies run a heavier brushed fleece (designed for sustained warmth). The quarter-zip dries faster after sweat exposure.
Is the quarter-zip available in ladies-fit?
Yes. Sport-Tek Ladies Quarter-Zip Pullover runs XS through 2XL in the same colorways as the mens cut.
How does the quarter-zip compare to the zip-up hoodie?
A quarter-zip has a half-length zip at the neck only; the body and bottom are pullover. A zip-up hoodie has a full-length front zip. The quarter-zip is lighter and more athletic; the zip-up is bulkier and warmer.
