FREDD MARSHALL Rho-Thermal 250 Men's Merino Wool Base Layer Set — Skiing, Thermal
A midweight 100% merino wool base layer set, top and bottom, built as the foundation of a cold-weather kit. Merino traps warm air against the skin, wicks moisture before it chills you, and resists odor naturally for multi-day trips. Fine-gauge fibers stay itch-free next to the skin.

Frequently Asked Questions
Is it itch-free for sensitive skin?
A: Yes. It uses fine-gauge merino fibers that bend rather than poke, making it soft enough for next-to-skin wear for almost everyone.
How do I wash it without shrinking?
A: Machine wash cold on a gentle cycle with a wool-safe detergent, no softener or bleach, and lay flat to dry. Do not tumble dry.
Can I use it for summer hiking?
A: The midweight is built for cold weather. Above about 60 F / 16 C it will likely be too warm; choose a lighter merino layer for summer.
Is the set top and bottom together?
A: Yes, this is the full set: one long-sleeve top and one full-length bottom in the same size.
Should I size up?
A: The athletic fit should sit close to function well. Size up only if you are between sizes or prefer a looser feel.
