Do you need something softshell fabric worthy of a deluge, or more of a water-resistant layer. If looking for a highly waterproof option, consider looking for a more technical fabric - the price is higher, but the quality is better in terms of waterproofness, durability, and breathability. Some fabrics are very lightweight and easily packable, a great option for popping into a backpack to layer over other clothing or use in warmer weather. Other fabrics have an insulating layer, making them a great all-in-one option for cooler weather. Light nylon may be perfectly sufficient if you're looking for a light-duty option. If, however, the garments will be worn regularly for work or play, consider a heavier-weight fabric, and perhaps adding knee and seat patches in a sturdy material. Synthetic materials are in some respects the easier option they tend to be lighter weight and a high-quality technical fabric can be a very effective waterproof layer.
Natural materials are heavier, more durable, and have less environmental impact, but you have to put in some work to make them waterproof. With maintenance, natural materials can last a long time, and are less of a "disposable" option than manmade materials. Another durable, natural-fibre option made from canvas or cotton duck, oilskin comes pre-treated with oils and/or waxes to make the fabric waterproof. Traditional oilskin may have a slightly greasy or waxy finish, which can transfer to other surfaces. Dry oilskin has a matte finish that does not transfer, so you may wish to look for this option. Oilskin often has a wonderful "distressed" finish with lots of texture and character. We love the classic look of oilskin and think it would make an amazing rain hat or utility overalls. Like canvas, the oilskin can be re-treated with waterproofing wax if necessary, and is an environmentally-friendly option with impressive longevity.
There is a wide range of nylon outerwear fabrics. They tend to be lightweight, flexible, and are a good option for making rain garments that are easy to roll up and pop into a backpack for an outing. Ripstop has a grid pattern in the weave, which as the name suggests, makes the fabric more durable and less prone to ripping. Cheaper nylon fabric tends to be uncoated, but because of the tight-weave will still offer water-repellent qualities. Coated nylon usually has a PUL (polyurethane) layer, or an aluminium backing that improves the waterproof qualities of the fabric look for a shiny clear, white, or silver backing. This is a great, lightweight "packable" option that is perfect to take along for a hike or pop into a child's backpack for a day of forest school. Uncoated nylon is very economical and may be used for light-duty play pants, whereas coated nylon offers good waterproofness.
These fabrics generally consist of a polyester "shell" outer layer, with 2- or 3-ply laminate coatings for waterproofness and breathability. As "technical" outerwear options, these fabrics tend to be more expensive, but may be worth it if you would like lightweight, durable, and reliable rain gear that will be worn regularly.Polyester laminates are generally highly waterproof, lightweight, and breathable. If you're using your rain gear regularly for high-intensity activities outdoors such as hiking, this is a comfortable option due to the breathability of the fabric. Most commonly made of polyester or nylon, softshell has a water-shedding outer layer laminated to an inner fleece layer. Softshell is growing in popularity - it is readily available in a wide variety of colours and prints, and is quite easy to work with. It is fairly thick and durable, and offers a good layer of insulation. The quality of softshell can vary quite a bit, with more technical fabrics offering spandex content for stretch, 3-layer construction, and better breathablilty.
