The design of these mid layer thermals is very similar to the Factor 1 in that they are manufactured from tubular fabric. The difference is that this fabric can be knitted on a wider variety of machine widths so we can produce garments without side seams in varying chest diameters. These thermal mid layers can either be worn over a base layer or next to the skin. They are designed to be snug fitting.

Sub Zero Mens Meraklon Thermal Mid Layer Leggings (with fly) are snug fitting with plenty of stretch (60% along the width, 40% along the length) which makes them feel as comfortable as a second skin and allows for a close comfortable fit for most body shapes. The in-built stretch also allows base layers to be worn underneath the Meraklon mid layers without being restrictive.

These mens thermal mid layer leggings have a double thickness fabric fly opening, providing extra thermal protection without the need for a zip. The high rise back will prevent any cold spots during activity and the low profile waist band will not cause bulk rub when combined with other mid layers or base layers. Double thickness fabric is also used on the cuffs, insulating your ankles from droughts.

Perfect for colder days where a base layer is just not warm enough on your commute, cycling, running or walking the dog, these thermal mid layer leggings offer an uncomplicated design with hypoallergenic properties.
