Buying technical clothing
Worn next to the body or over a base layer, and made of water-repellent synthetic fibres such as polyester or polypropylene, technical garments wick away most of the perspiration produced by an active body, while at the same time have an insulating factor that can vary according to the model and brand.
Three different types of technical garments are generally used for summer wear: those made from polar fleece, so-called soft shell styles, and waterproof-breathable hard shell designs. Which should you choose? It all depends on what you need.
If you’re on a tight budget and you’ll only be out hiking, biking, camping, etc. occasionally, when the weather’s good, or if you’re looking for something to keep you warm on a slightly chilly summer night, start with polar fleece.
Made of lightweight polyester, polar fleece-type garments are tops at wicking away moisture while keeping you warm, and dry quickly. They can be worn alone in average temperatures, or over a synthetic fibre base-layer garment when it’s colder. Some styles also incorporate a wind-blocking coating. For summer use, a 100-weight fleece is more than sufficient.
