Warranty and consumer rights

Under the consumer rules explained by the Consumer Goods and Services Ombud, every item you buy has an automatic six-month warranty that it will comply with the stated requirements, in addition to any other warranty the seller gives. Keep your proof of purchase, and ask the seller to confirm in writing which warranty applies to the set you choose.

Season and when to buy

Winter runs from June to August, when thermal underwear is worn most, and summer runs from December to February. Buying in November gives you time to wash and wear the set before the cold months begin.

Sizes, fabrics and delivery

Listings use sizes such as S, M, L or 3X-large, so compare the waist and leg length in centimetres with the seller's size chart before you order. Fabrics vary: listings mention brushed, bamboo, organic cotton and ski base layer materials, each with its own warmth and feel. Ask whether a seller in Johannesburg, Cape Town, Durban, Pretoria or Gqeberha can post the order to you, and what delivery costs, because the same item can differ in total price between sellers.

What to write in your request

Say who the underwear is for, whether it is for daily wear, hiking, skiing or work, and the item you want, such as long johns, a top or a set. Give the material you prefer, the warmth level, the size and the colour. Add your budget in rand and the city where the order should be delivered.
