Unfortunately for Claire and I, your dear testers, it means many many miles in pretty miserable conditions. At every wet opportunity, I've been out both on and off road, trying my best to find weaknesses in each of these options to bring you the best possible information.

Gore-Tex encompasses many different flavours of waterproof fabrics, from Gore-Tex Pro (the absolute highest level of protection, great if you’re going up K2, but not nearly breathable enough to handle high output activities like cycling), through to Gore-Tex Infinium (not really waterproof, but can shrug off rain and is incredibly breathable for use in changeable conditions). The RRP is effectively the same as the Endura GV500, but both are regularly discounted and while for the same money, I’d recommend the Endura model, if the dhb Trail is reduced and the Endura isn’t when you’re looking to buy, then the performance is similar enough for the dhb to become the better choice. Plus, all of these pores are each about 700 times bigger than a molecule of water vapour, which means sweat can escape much easier if you up the ante or if the temperature rises. With the hood up, which is best under a helmet or the face box gets very claustrophobic, you feel more or less impervious to the elements. The lower hem can be easily cinched one handed with an easy drawstring, which I'd ideally liked to have seen complimented by adjustable cuffs. Yes, you can fit gloves underneath with ease, but I often go without gloves, and breezy cuffs in the cold are not the one.The cut is for MTB riding, and is pretty true to size. Given the more relaxed cut, opt for your usual jersey size for this one.Claire found she could probably go for a smaller size, but the looser fit worked well for us both when it comes to layering potential. The dropped tail isn’t as pronounced and the sleeves aren’t quite as long as others, but despite this, it works very well for blasting around the woods at full gas. It’s noticeably more breathable than the other options on the list, and the real bonus is the hood, which can be adjusted easily while riding and doesn’t leave your face being squashed by the face box. The breathability is further enhanced by stretch panels under the armpits, which function as pit perforations do whilst also improving the freedom of movement. My major gripe with the dhb Trail was the hood: It’s too small to reasonably go over a helmet without the face box being squashed right against your nose and mouth. It’s fine for short downpours, but for extended ones, you’ll want it under your helmet.

It essentially came about as a happy accident – Bob Gore discovered a new form of polymer made of large molecules that repeat to form long chains. If you want something to ride to work in every day and use in the woods at the weekend you’ll have a hard time finding an option that does both as well as the POC Motion. Plus, especially in the lovely Dioptase petrol blue colour, it’s another looker that’s perfectly fine on the office floor. Indeed, Gore-Tex promise that each of their products provide at least three core benefits: waterproof (even in the heaviest storms), windproof and breathable. He found that, by yanking a material called PTFE (polytetrafluoroethylene), the polymer stretched by 1,000 per cent to create a microporous structure we now know as Gore-Tex, How is Gore-Tex made? Gore-Tex swapped the polyurethane layer typically found on raincoats with a Teflon membrane which bonded with the nylon outer layer. This where those millions of pores are found, thus facilitating brushing off water and passing water vapour away from your skin.Durable water repellent, or DWR, is your wet weather gear’s first line of defence. It’s not a laminate or coating but a treatment applied to the fabric’s outer surface.

These are softshell tops that feel like a jersey but use a waterproof membrane or DWR (durable water repellent) treatment to repel precipitation. Every square inch of the extremely thin Gore-Tex membrane has nine billion pores, with each of these holes 20,000 times smaller than a drop of water.With Shakedry, Gore turned the structure of membrane-based waterproofs inside out. Instead of sandwiching the membrane in the middle of a laminate, the membrane in Shakedry fabrics forms the outermost layer of the garment, supported by a single fabric layer.

Conversely, doing threshold efforts in it will probably leave you damp from your own perspiration, so it's one for the classic long-and-slow winter riding gang. It comes up a little small, so as per Rapha options you’ll need to size up from your jersey. However, DWR treatments wear off over time, accelerated by abrasions and some detergents. When this happens, the fabric no longer causes water to bead and will become saturated and heavy.Waterproofness is generally measured in terms of how much water, in mm, can be placed on top of a fabric in a column until it seeps through (though some companies dispute whether this testing method accurately represents real-world conditions). In simple terms, bigger numbers ought to mean the garment’s fabric can withstand more water before any leakage occurs. For commuting especially, some level of additional visibility is definitely advantageous, be that a bright colour or reflective details. Off-road away from traffic, this will obviously be less of a concern. The fabric is gossamer thin to the point of translucency, with a light stretch to it. The fit is most definitely race, though the tail could be dropped further. I usually wear a small jersey, and a small Supreme is on the cusp of being too tight, especially in the forearms, so if you want to account for a mid-layer then I suggest you size up.
