Sharkskin Chillproof Long Sleeve Full Zip Top (Junior)

The Sharkskin Chillproof Long Sleeve Full Zip Top (Junior) is a warm in-water top for kids who start shivering long before the adults are ready to get out. It works well for young snorkelers and junior divers, and it gives a lot more cold protection than a standard rash shirt. It also blocks the wind once they are out.

How Chillproof Keeps Kids Warm

Chillproof is a three-layer composite built for the water. Sharkskin rates its warmth as similar to a 2.5 to 3mm neoprene wetsuit, though it is far easier to pull on and take off. Kids can wear it alone or layer it under a wetsuit.

• A windproof membrane that breathes, so kids stay warm without overheating
• Soft hollow fiber fleece against the skin that wicks moisture
• Neutrally buoyant, so no extra weight is needed when diving
• UPF50+ sun protection

The full-length zipper and high collar are the real conveniences here, since kids can zip up in the wind and open it partway when the sun comes out.

Junior Fit and Sizing

This is a unisex fit, and sizing follows age. It comes in sizes 4, 6, 8, 10 and 12. The four-way stretch fabric moves with active kids and makes getting dressed on a wet deck much less of a struggle.

Frequently Asked Questions

Can my child wear the Chillproof Junior top under a wetsuit?

Yes. Sharkskin designs Chillproof to be worn under a wetsuit for added warmth and wind protection, or on its own as thermal wear.

How do I choose a size for the junior full zip top?

Pick the size that matches your child's age. The junior range runs from size 4 to size 12 in a unisex cut.

Is this top better than a rash guard for snorkeling?

For kids who get cold, yes. It adds real thermal protection, while a rash shirt mainly covers sun.
