Men's Underwear Types: 12 Styles Compared for Fit & Comfort
Men's underwear types are sold under dozens of names, but nearly every cut in a man's drawer belongs to one of twelve families. This guide compares each family by coverage, rise, support and the day it's actually built for — no label soup, no filler. Every type links to its live collection so you can move from reading to shopping in one click. If you have ever stood in a store aisle wondering what separates a trunk from a boxer brief — or ended up searching types of male underwear at midnight — this is the page that ends the confusion.
What Are the Main Types of Men's Underwear?
Retailers invent new names faster than guys can learn them, so it helps to sort every style along three axes instead of memorising labels:
- Coverage — how much fabric wraps the seat and thigh, from a bikini brief's narrow side to a boxer short's full leg.
- Rise — where the waistband sits, from low-rise (below the navel) to high-rise (at the natural waist).
- Support — whether the front is a flat fly, a separated pouch, or a strapped jockstrap cup.
Cross those three axes and you get twelve families of male underwear types — the same categories any mens underwear types chart lists, explained by what each one actually does: briefs, boxer briefs, trunks, boxer shorts, bikini briefs, thongs (g-string, v-string, t-back), jockstraps, pouch underwear, cock socks, long johns, swimwear, and sheer-mesh or bodysuit styles. Different types of mens underwear are really just different combinations of the same three dials — which is why this guide sticks to twelve instead of thirty-eight.
Briefs vs Boxer Briefs vs Trunks: The Core Three
Three cuts handle most of a man's week. Learning the difference between them is 80% of understanding mens underwear styles.
Briefs are the original: minimal fabric, a full seat, zero thigh coverage and a front that either lies flat or lifts into a pouch. They are the only classic type that never adds bulk under tailored trousers, and they stay put under slim denim. On DomiGe, the brief is where the 95% Modal story lands hardest — modal drapes softer than cotton and resists pilling through dozens of washes.
Boxer briefs add thigh coverage to the brief's support, which kills the chafe that longer strides create and keeps everything anchored during a workout or a long walk. The leg length is the whole story: a 3–4 inch leg supports without riding, while anything past 6 inches starts creeping up under shorts. Boxer briefs are the default answer for guys who want one cut that works in the gym and the office.
Trunks are boxer briefs with the leg cut shorter and the rise lower — typically a 2–3 inch leg sitting below the navel. They read more modern under low-rise trousers and slim shorts, and they show less waistband line under a fitted shirt. The trade-off: less thigh coverage means more friction on long runs.
Rule of thumb: tailored trousers → men's briefs or trunks; denim and chinos → boxer briefs; lounging → boxer shorts.
Thongs, G-Strings and V-Strings Explained
The minimal-coverage family confuses people because three names get used interchangeably. They are not the same:
- Thong — the umbrella term: a pouch front with a seat that narrows to a single strap or string.
- G-string — the most minimal version: a thin string back with almost no seat fabric.
- V-string — a thong whose back strap forms a V across the upper seat, giving slightly more coverage than a g-string without the full seat of a brief.
- T-back — a single strap meeting a waistband band in a T shape; common in bolder cuts.
Men's thongs exist for three practical reasons: zero visible panty lines under trousers and leggings, no ride-up under shorts in heat, and a silhouette that stays smooth under fitted clothing. They are also the family where fabric quality matters most, because less fabric means every seam touches skin. DomiGe cuts these in modal and breathable mesh so the strap stays soft through a full day — browse the full range of men's thongs to see the differences side by side.
Jockstraps and Pouch Underwear Compared
Both styles solve the same problem — separating and supporting the front — but they do it for different occasions.
Jockstraps were built for sport: a waistband, two leg straps and a pouch that holds everything in place during explosive movement. Modern jockstraps keep the anatomy but swap the scratchy originals for modal and mesh pouches with double straps. They remain the highest-support type per gram of fabric, which is why they never left the gym — and why they have become a fashion statement in their own right.
Pouch underwear brings the same separated-front engineering to an everyday brief or boxer brief cut. Instead of straps, the pouch is sewn into the garment, so you get the anti-squash benefit without the athletic look. DomiGe's Comfort Pouch™ is this idea taken seriously: an ergonomic front room that separates and lifts, cutting the heat and friction that flat-front briefs trap.
Choose by day: jockstrap for training and statement looks; pouch briefs for everything you wear under normal clothes.
Boxer Shorts, Bikini Briefs and Long Johns
Boxer shorts are the relaxed, lounge-first cut: a straight leg, no thigh hug and usually a woven or soft-knit fabric. They breathe more than any other type, which makes them the sleep and weekend default, but the loose leg means they bunch under trousers. Knit boxer shorts drape better than woven ones under clothes.
Bikini briefs are briefs with a narrower side and a lower rise — the swim-inspired cut that shows the least waistband of any underwear type. They work in heat, under tight trousers and as a base under short shorts.
Long johns are the one family that is not really underwear at all — they are a thermal base layer that happens to sit in the same drawer. Cut close with a slim leg so they layer under trousers without bulk, and strongest in merino or high-quality modal rather than cheap polyester. If your winters involve commuting, long johns matter more than any other cut on this list.
Swimwear, Sheer Mesh and Bodysuit Styles
Three smaller families round out the twelve. Swimwear — swim briefs, swim trunks and board shorts — is cut from quick-dry fabric with a lining or pouch structure that survives chlorine and salt; it is not interchangeable with underwear, because cotton and modal hold water and lose shape. Sheer and mesh styles use open-knit or semi-transparent fabric for airflow and a bold look; the mesh replaces solid panels, so fit and pouch construction matter more than coverage. Bodysuits and wrestling singlets extend the torso into a one-piece, holding everything flat under fitted tops and eliminating the untuck that plagues longer torsos.

Twelve rows, twelve families — everything else in the store is a variation on one of these.
How to Choose by Body Type and Activity
The right types of underwear for men depend less on fashion than on geometry. Match the cut to your body and your day:
- Thicker thighs — boxer briefs or boxer shorts; briefs and bikini cuts ride up and chafe.
- Taller torso — mid or high rise; low-rise cuts migrate downward when you sit or bend.
- Athletic build — pouch briefs or jockstraps; the separated front holds shape during movement.
- Office days — briefs or trunks under tailored trousers; boxer shorts bunch and print through slim fabric.
- Training — jockstrap or moisture-wicking boxer brief; cotton soaks sweat and stays heavy.
- Cold commutes — long johns under your normal cut, or on their own on the coldest days.
- Sleep and weekends — boxer shorts or a cock sock; the point is airflow.
If you only rebuild one part of your drawer, make it the cut you wear most — for most men that is the boxer brief or the pouch brief, and upgrading the fabric there changes every day.
Men's Underwear Size and Rise Guide
Two measurements decide fit: waist and hip. Measure the waist at the band you actually want, and the hips at the fullest point; when the two land in different sizes, size to the waist and let the stretch in the fabric handle the seat. Men's underwear types are cut in M through 4XL, and the bigger sizes are not just scaled-up versions — 4XL men's underwear patterns add seat room, longer rises and wider waistbands so the band does not roll and the leg opening does not cut in. If you have ever found that plus sizes fit like a smaller size with extra fabric in the wrong places, this is why.
Rise is the second dial. Low-rise sits 1–2 inches below the navel and suits shorter torsos; mid-rise sits at the navel and is the safe default; high-rise reaches the natural waist and stays put when you bend. Low-rise in a long torso means constant adjusting; high-rise on a short torso means the waistband disappears under a shirt hem. Test one mid-rise cut first, then adjust up or down.
Fabric Guide: Modal, Cotton, Mesh and Bamboo
Coverage decides how a type looks; fabric decides how it feels at hour nine.
- Modal — the all-rounder. Softer than cotton, draps close, resists pilling, and dries faster than cotton. DomiGe uses 95% Lenzing Modal for exactly this reason, paired with the Skybridge™ side strap that keeps the band from rolling.
- Cotton — the heat and sweat choice. Breathes better than modal when you are actually working, but holds moisture and loses softness over time unless it is long-staple cotton.
- Mesh and sheer knits — maximum airflow. Ideal for minimal cuts where the mesh replaces panels instead of layering over them.
- Bamboo viscose — modal's cousin: soft and breathable, slightly less elastic recovery. Fine for lounging cuts.
Merino belongs on this list too, but only for long johns — it is the one fabric that stays warm without bulk and resists odour across multiple wears.
How to Care for Each Underwear Type
Most men's underwear types die from laundry, not wear. Cold water, gentle cycle, and hang or low-heat dry will double the life of any cut on this page. A few type-specific rules: modal and bamboo go in cold and never into high heat, which flattens their elasticity; mesh and sheer styles belong in a wash bag because the open knit snags on velcro and hooks; long johns wash inside out to protect the face of the fabric; swimwear rinses in clean water after every swim or chlorine eats the elastane. Replace a cut when the waistband stops snapping back or the pouch loses its shape — stretched-out support is the first thing to go and the last thing people notice.
Men's Underwear Types FAQ
What are the most common men's underwear types?
Briefs, boxer briefs, trunks, boxer shorts and thongs. Those five cuts cover what most men wear daily; the other seven families on this page serve specific jobs like sport, heat, cold or bold styling.
What is the difference between trunks and boxer briefs?
Leg length and rise. Trunks carry a 2–3 inch leg and a low rise; boxer briefs carry a 3–6 inch leg and a mid rise. Trunks disappear under slim trousers; boxer briefs support and prevent chafe on longer legs.
Are jockstraps only for sports?
No. The jockstrap is the highest-support construction in men's underwear, and modern versions in modal and mesh are worn as everyday pouch support and as a fashion statement well outside the gym.
Which men's underwear types work for hot weather?
Cuts with airflow and low coverage: bikini briefs, cock socks, mesh and sheer styles, and moisture-wicking boxer briefs. In humid heat, the fabric matters as much as the cut — mesh beats solid cotton at hour nine.
How many types of men's underwear are there?
Mens underwear types fall into twelve families that cover effectively everything sold: briefs, boxer briefs, trunks, boxer shorts, bikini briefs, thongs, v-strings and t-backs, jockstraps, pouch underwear, cock socks, long johns, swimwear, and sheer-mesh or bodysuit styles. Labels beyond those are variations, not new types.
