Quarter Zip Summer T-Shirts

Yes, the flame-resistant protection is built into the fabric construction itself, not a surface coating, so the lighter 6oz weight doesn't reduce safety performance. The 7% spandex content is added purely for stretch and comfort and doesn't compromise the FR rating.

The spandex content allows the fabric to stretch and move with your body during reaching, bending, or climbing, which a rigid 100% cotton fabric can't do as easily. This makes the quarter zip a good option for jobs that combine hot conditions with a lot of physical movement.

A quarter zip only opens partway at the neck, giving you some ventilation without the bulk of a hood or a full front zipper, making it lighter and less bulky for hot weather. A full zip FR hoodie offers more adjustability and hood coverage but is generally better suited to cooler conditions rather than peak summer heat.

Wash in cold or warm water with a mild detergent, avoiding bleach, fabric softeners, and starch, since these can weaken the flame-resistant properties and affect the stretch recovery of the spandex blend. Tumble drying on low heat helps the fabric retain its shape and stretch over repeated washes.

The NKE FR Lightweight Flex 1/4 Zip Sweatshirt comes in Black and Charcoal Grey, both made from the same 6oz cotton-spandex blend. Both colors offer identical protection and performance, so the choice comes down to personal or uniform preference.

The quarter zip works well as a standalone top in warm to hot conditions, offering enough coverage and protection on its own for most summer job site tasks. In cooler mornings or transitional weather, it can also be layered under an FR jacket without adding much bulk.
