Men's Lounge Pants

Men's lounge pants from Mariner Underwear are cut from the same pure cotton poplin and jersey fabrics as the rest of the nightwear range. Wear them at home in the evening, pair them with a matching top for a full pyjama set, or put them on as a standalone bottom when you want something more relaxed than jeans. The elastic waistband sits comfortably without leaving a mark, and the straight-leg cut gives you room to move around the house.

If you want a comfortable pair of lounge pants in cotton, these are the bottoms for you. Browse the collection and pick a plain, striped or checked style from the men's loungewear range.

Cotton Fabrics: Poplin or Jersey

The lounge pants in this collection come in two main fabric types. Pure cotton poplin is a tighter weave with a smooth surface. It holds its shape well and feels comfortable against the skin all evening. Combed cotton jersey is softer and more flexible, with a slight stretch that makes it a good choice if you move around a lot at home. A few styles combine a jersey top with a flannel bottom panel for extra warmth in winter.

Some styles are 100% combed cotton throughout. Others blend cotton with a small percentage of polyester in the bottom panel to add shape retention over time. The fabric composition is listed on each product page so you can choose the right pair for your needs.

Styles and Prints Available

The range offers solid-colored models (navy and petrol blue) as well as striped or checked versions. The checked styles feature a Scottish tartan-style pattern in shades of blue. Geometric patterns adorn some of the poplin models. If you prefer a more understated look, the solid navy and fine-striped versions are the most discreet options in the collection.

Regardless of the chosen pattern, every pair of lounge pants features the same cut and sizing, along with an elasticated waist, often with a drawstring and a fly opening. The poplin trousers have a straight-leg fit, whereas the flannel trousers, designed for cooler evenings, feature ribbed cuffs at the ankles.

Sizes

Lounge pants from Mariner Underwear are available in sizes S to XXL. The sizing runs true to your usual clothing size. Because these are worn around the house rather than to a tailored fit, you can take your usual size without going up. The elastic waist adjusts to fit and there is enough room in the leg for comfortable movement. Check the size guide on the product page if you are between sizes.

Lounge Pants vs Pyjama Bottoms

The difference between lounge pants and pyjama bottoms is mostly in how you use them. Pyjama bottoms are part of a sleep set, worn with the matching top and put away in the morning. Lounge pants work the same way but are also comfortable enough to wear through the evening before bed, at a desk if you work from home, or on a lazy weekend morning. The cotton fabrics in this range are breathable enough for both uses.

If you want a complete sleep set, pair the lounge pants with a matching top from the men's pyjama bottoms range. If you just want a comfortable bottom to wear at home, the lounge pants work on their own with a t-shirt.

Care

Wash your lounge pants at 30 degrees, turned inside out. Avoid fabric conditioner on the cotton, which reduces its breathability and softness over time. Line dry rather than tumble dry to keep the fabric in good condition and the elastic waistband holding its shape. With straightforward care, a well-made pair of cotton lounge pants will last several years of regular use.

Complete Your Home Comfort Range

If you are building out your home wardrobe, the men's loungewear collection covers the full range of styles including tops and sets. The men's pyjamas collection includes matching top and bottom sets in the same cotton poplin and jersey fabrics. A Mariner Underwear dressing gown over the top completes the look for a full evening-in outfit.
