Thunderpants might just be the the world’s most comfortable pair of underwear. Celeste Sipes, owner of Thunderpants USA, has been refining the Thunderpants design, materials and prints for years — all in the name of ultimate comfort for your intimate areas. Each pair of Thunderpants is made from fair trade certified New Zealand organic cotton yarn, which is grown without the use of any synthetic chemicals, fertilizers, pesticides, AZO dyes, heavy metals, formaldehyde or chlorine. Thunderpant’s insanely comfortable fabric is dyed and milled in Melbourne, Australia and every pair is cut and sewn in a women-owned, minimal-waste factory in Hillsboro, Oregon. Thunderpants works with local artists from Portland, Oregon to make their unique, eye-catching prints and designs. You won’t know how comfortable you’ll be in a pair of Thunderpants until you throw them on and see for yourself!
