Cotton sweat shorts work best when you pick them by length, waistband and pockets rather than by looks alone: a 5-inch inseam with a stretch waist and secure pockets covers the gym, a run, an evening at home and a quick coffee run. Here is how to choose a pair and how to wear them in each setting.
Why cotton shorts are the easy everyday choice
Cotton is soft, breathable and forgiving. It does not cling the way some synthetic fabrics do, and it feels natural against the skin on a warm day or a slow Sunday. Our Cotton Running Shorts are 100% cotton and are described as soft, breathable and moisture-wicking.
- Soft from the first wear: no stiff break-in period.
- Easy care: machine wash cold, no bleach.
- Flexible: they work for sport, casual days and sleep.
Length: what 5 inches actually looks like
A 5-inch inseam is about 13 cm and sits above the knee. It is short enough to move freely and long enough to feel like proper shorts rather than swimwear. If you prefer a looser, more relaxed feel, size up.
| Occasion | What to look for |
|---|---|
| Gym and running | 5-inch length, secure zip pockets, stretch waistband |
| At home | Soft cotton, relaxed size, simple waistband |
| Out and about | Solid colour such as black or army green, clean fit |
| Sleep | Light, quiet fabric with nothing that digs in |
Pockets that stay closed
Loose pockets are the usual complaint with sports shorts: keys and phones bounce around. The Cotton Running Shorts have three zip pockets, two at the sides and one at the back, with AK logo zips. That lets you run with a key or card and not think about it.
How to size them
Use your waist measurement and compare it with the size guide on the product page. For the Cotton Running Shorts the waist ranges are:
- S: 74-84 cm (29-33 in)
- M: 78-88 cm (31-35 in)
- L: 84-94 cm (33-37 in)
- XL: 92-102 cm (36-40 in)
- XXL: 102-112 cm (40-44 in)
If you sit between two sizes, choose the larger for lounging and the smaller for training.
Light alternative for hot evenings
When cotton feels like too much, the Split-Side Lounge Shorts are silky and lightweight, with deep side splits, an elastic waistband and a built-in liner. They are made for lounging, sleeping, yoga or the beach, in sizes S to XL.
What to wear underneath
Cotton shorts are roomy, so a snug cut underneath keeps everything in place and stops fabric bunching. Good partners are cotton boxer briefs or low rise briefs. See our guides on the best men's underwear for the gym and low rise underwear.
- The Cotton Boxer Brief is 95% cotton and 5% spandex with a contoured 3D pouch.
- The Cotton Sport Briefs are 93.2% cotton and 6.8% spandex with a 1.5-inch logo waistband.
Care: keep them soft
Wash cold, skip bleach and avoid dry cleaning, as the care instructions say. Turn zip pockets closed first so the zips do not snag other items. More tips are in our guide on how to wash men's underwear.
