Iceglad Mock Turtleneck Thermal Undershirt vs Port & Company Essential Mock Neck Long Sleeve

The Port & Company Essential Mock Neck is the safer buy for most shoppers. It has a heavier 6.1 oz soft-spun cotton body, rib knit collar and cuffs, and a published size chart, and it rates higher with more owners (4.7 from 135 versus 4.3 from 82). The Iceglad is a lighter thermal-style pullover sold mainly in black, with less sizing detail and a smaller review base. Pick the Iceglad only if you want a thin base layer; pick the Port & Company for a shirt you wear on its own.

• Choose the Iceglad if you want a thin cotton mock turtleneck to wear as a base layer under sweaters or jackets.
• Choose the Port & Company if you want a heavier mock neck shirt with ribbed collar and cuffs that holds its shape and works on its own.
