What is SPF?

SPF stands for Sun Protection Factor. It measures how much solar energy (UV radiation) is required to produce sunburn on protected skin (i.e., in the presence of sunscreen) relative to the amount of solar energy required to produce sunburn on unprotected skin. As the SPF value increases, sunburn protection increases. 

What is UVA and UVB rays?

UVA and UVB are ultraviolet rays given off by the sun proven to contribute to the risk of skin cancer. Ultraviolet A (UVA) is associated with skin aging. Ultraviolet B (UVB) is associated with skin burning. 

UVA and UVB differ how they affect the skin but they both do harm. Unprotected exposure to UVB and UVA damages the DNA in skin cells, producing genetic defects, or mutations, that can lead to skin cancer (as well as premature aging). These rays can also cause eye damage, including cataracts and eyelid cancers.

What is UPF?

UPF stands for Ultraviolet Protection Factor and is the rating given to clothing for its broad-spectrum protection against both UVA and UVB rays. SPF in sunscreen measures only effectiveness against UVB rays, while UPF measures protection against the full spectrum of ultraviolet radiation (UVB and UVA).

What does UPF 50+ mean?

The 50 represents the factor to which the clothing protects the skin. UPF 50 fabric blocks 98% of all UV rays. The "+"symbol indicates the fabric testing can block more than 98% of the UV rays.

What is UPF Clothing?

UPF clothing is a form of clothing that utilizes specially designed fabrics which means that less skin is exposed to the sun. UPF 50+ is the highest rating for sun protective clothing.

Why is PYT more expensive than other brands?

PYT goes above and beyond to ensure all our fabrics meet the UPF 50+ rating. This includes third party testing and creating specialized fabrics that are woven in a manner to make the fabric impermeable to UV rays. 

Do I still need to wear sunscreen if I’m wearing PYT?

If your skin is exposed, YES! We recommend protecting all your skin with a combination of clothing, hats, sunblock and lip balm of SPF 30 or higher. Don’t forget the sunglasses! Eyes are susceptible to ocular melanoma, and UV damage contributes to cataracts and macular degeneration. 

When should I use sunscreen?

Every day if you will be outside. The sun emits harmful UV rays year-round, even on cloudy days. 80% of the sun’s harmful UV rays can penetrate your skin. 

Snow, sand, and water increase the need for sunscreen because they reflect the sun’s rays.
