Questions about the thermal knit bottoms
How do the thermal bottoms fit?
Snug. The circular-knit fabric is made to sit close to the body so it layers under pants, with an elastic waistband and ankle cuffs.
Are the thermal bottoms warm enough for winter?
They are a thermal base layer meant to add warmth and a barrier against wind under your clothes. Pair them with appropriate outerwear for the coldest conditions.
Are the thermal bottoms flame resistant?
No. They are not flame-resistant (FR) apparel, are not NFPA certified and are not PPE or turnout gear.
Can I wear them as pajamas?
Yes. Rothco designs them to work as a base layer or as standalone sleepwear.
