Woolpower's Long Johns with Fly 400 are a heavyweight, circular-knitted merino wool base layer for men, built from the brand's thicker Ullfrotté Original 400 fabric — 70% merino wool, 28% polyamide and 2% elastane. The circular knit construction eliminates the lengthwise seams that can otherwise chafe under other layers, and a thick terry-loop knit on the inside traps considerably more air than the 200-weight fabric, giving noticeably greater insulation for the coldest, least active days outdoors. The wool continues to wick moisture away from the skin even as it insulates, so the garment stays warm rather than clammy over long periods. A sewn-in gusset at the crotch allows a full range of movement and adds durability at a high-wear point, while knitted-in cuffs at the ankles stop the legs riding up inside boots or overtrousers. The practical fly adds convenience out in the field. Best used as an insulating second or mid layer — under overtrousers or salopettes — during extended spells of cold-weather stalking, hunting or other low-intensity outdoor work where warmth matters more than breathability. Machine washable at 60°C.
