A downside of this system is that without a PU film, the membrane may be more prone to contamination. It is possible to build an oleophobic treatment into the membrane but this may be less effective or durable than the traditional GORE-TEX method. Pores left open will breathe better but may become clogged with oils and dirt more easily, meaning you may need to wash the garment more regularly. Wearers may also experience more rapid cooling in high windchill situations, though garments will still be roughly 95% windproof. Layer (e.g. GORE-TEX Performance) - outer & membrane are bonded together, but the internal lining is a loose-hanging fabric or mesh

Founded in 1997, we’re the UK's largest dedicated outdoor clothing and equipment retailer and have been offering our customers unbeatable VALUE for money and outstanding quality for 25 years. Over the years many brands have made conscious efforts to utilise more environmentally friendly, perfluorochemical-free (PFC-free) DWR treatments to help reduce the level of PFCs released into our waterways.These fabrics all utilise an ePTFE membrane without a protective PU film (or in some cases with a PU film that encircles the pores, leaving them uncovered). Since there's no cover over the pores, the membrane is able to breathe more effectively. Fabrics like this can take air in as well as pushing moisture out. It's a two-way airflow that disperses moisture by convection (air circulation) as well as diffusion (pressure gradients). Good alternatives to GORE-TEX are also available, such as FUTURELIGHT™ from The North Face, Pertex Shield, and less expensive PU film fabrics like Patagonia’s H2No. There are a variety of tests and measures used to quantify performance but none are standardised or accepted industry-wide. The important thing is to take any quoted figures you see with a pinch of salt and bear in mind that a variety of factors – for instance the type of face fabric or the taping pattern used - can affect the performance of individual styles. The minimum level of breathability achieved using DryVent: 600g/m²/24 hours on the Moisture Vapor Transfer Rate scale.

GORE produces some of the most well-known waterproof materials.Their range includes fabrics such as GORE-TEX Pro, which gives waterproof and breathable protection in the harshest conditions, and GORE-TEX Active, which provides highly breathable and waterproof performance perfect for those moving fast and light. Please note this is not an exhaustive list, it simply highlights key technologies in our range. The North Face DryVent For long walks and hikes, little feet will love the Drift Waterproof Boots. They provide ultimate protection and support, thanks to a high traction outsole and a synthetic and mesh upper. Find them with elastic laces and a rip strap fastening for extra support and to ensure your child’s shoe stays where it belongs – they’re feet! Layer (e.g. GORE-TEX Paclite) - outer & membrane are bonded together with a very thin internal carbon or textured 'half layer' on the insideSo, whether you're planning on travelling the world or exploring closer to home, we have what you need for your next ADVENTURE.
