Bad workout underwear bunches, traps sweat, and turns a good session into a constant adjustment job. The right pair gives you support without pinching, keeps the legs in place, and cuts down on friction. Here are five options for different training needs, starting with Sly Collective Underwear.
1. Sly Collective Underwear, Bamboo Support With an Anatomical Hammock Pouch
Sly Collective Underwear is our first pick for men who want one pair to handle support, heat, and thigh rub. Its bamboo pouch underwear uses an anatomical hammock pouch, longer legs, and an anti-chafe cut.
That pouch gives the scrotum its own space instead of pressing everything flat against the body. It also helps keep the fabric from rubbing where it hurts most. The longer leg can sit more securely on the thigh during squats, lunges, and treadmill work.
The fabric is naturally moisture-wicking, which helps move sweat away from the skin during a session. Bamboo also gives the product a clear sustainability angle. Bamboo is a fast-growing grass, although the full environmental impact still depends on how the fibre gets processed.
The main caveat is fit. A pouch needs room in the right places, while the waistband and legs still need to stay firm. Check the size guide before ordering, especially if you sit between sizes. For men tired of choosing between eco values and workout function, this is the most rounded option in the group.
Our broader guide to men’s underwear for gym workouts covers how pouch shape and leg length change the feel during training.
2. Runderwear Running Boxer, A Low-Friction Choice for Running
Runderwear Running Boxer is suited to running. Its seamless design eliminates chafing, making it a practical choice for runners.
Running underwear can be useful when repeated movement makes seam pressure uncomfortable. A boxer style provides coverage during a run.
This style focuses on reducing friction rather than adding extra features. Choose it when chafing is the bigger concern during a run.
Chafing is skin damage caused by repeated rubbing. Reducing friction can help address that concern during running.
Use this style for running. Its seamless design is a straightforward choice when chafing is the main problem.
Our advice from SLY Collective underwear for chafing explains why a longer boxer brief can work better than a short trunk when the thighs rub.
3. Anatomical-Support Boxer Briefs for Training and Thicker Thighs
Anatomical-support boxer briefs suit men looking for a long-lined cut for thicker legs, squats, and lunges. This type of underwear can work for training and mixed gym sessions.
A bamboo material and longer leg line provide coverage through movement. A longer cut can be useful for thicker thighs when you want stable coverage during lower-body exercises.
An anatomical pouch provides defined front support. Ride-up-resistant panels can also help the garment stay in place during training.
When comparing this type of underwear, look for clear wording about the material, leg length, anatomical pouch design, and ride-up-resistant panels.
This category is suited to training where stable coverage and an anatomical pouch are priorities. Check the stated construction and fit details before you buy.
4. Running Briefs, Lightweight Moisture Management for Sweaty Sessions
Running briefs suit men who dislike extra fabric during hard cardio. The brief cut leaves the upper thigh clear, which can feel cooler during running, circuits, or indoor training.
The key feature is moisture management. Synthetic performance fabrics are often made to move sweat away from the skin and dry faster than cotton. That matters when you train, change clothes, and head straight into the rest of your day.
Briefs also remove one common failure point: loose fabric around the thigh. There is less material to roll up. The trade-off is less coverage if your thighs rub together, so this cut does not solve every chafe problem.
Some running briefs use a contoured front for support. Others keep the shape simple. A close fit can feel secure, but it should not squeeze or leave deep marks after the session.
Independent running tests often assess underwear after easy runs, long runs, and faster intervals. That range matters because a pair that feels fine for ten minutes may feel damp or restrictive after an hour. For more detail on fabric choice, to SLY Collective moisture-wicking men’s underwear.
Pick this style when sweat is your main complaint. If thigh rub or pouch support causes more trouble, move back to a longer boxer brief with a shaped front.
5. Long-Lined Boxer Briefs for Thicker Legs, Squats, and Lunges
Long-lined boxer briefs can suit thicker legs and lower-body movements such as squats and lunges. The long-lined shape provides coverage through these exercises.
Bamboo is one material used in this type of underwear. A bamboo construction can be paired with a long-lined fit.
Look for ride-up resistant panels when keeping the leg fabric in place is important. These panels can help provide a stable fit during movement.
An anatomical pouch is another available detail. This pouch provides a defined front construction rather than a plain, flat front.
This category is suited to training that includes squats and lunges, particularly for men with thicker legs. The long-lined shape, bamboo material, anatomical pouch, and ride-up resistant panels are details to consider.
Use the decision rule this way. If thicker legs and repeated squats or lunges are your main concerns, start with a long-lined boxer brief with ride-up resistant panels. If you prefer a different cut, compare the leg length and pouch design before choosing.

Frequently Asked Questions
What is the best underwear for working out?
The best underwear for working out is the pair that solves your main comfort problem. For general training, Sly Collective Underwear combines a bamboo fabric with an anatomical hammock pouch, anti-chafe design, and longer legs. Runners may prefer a smooth boxer, while men who sweat heavily may prefer a lightweight quick-dry brief.
Are boxer briefs good for working out?
Boxer briefs are good for working out when the legs stay in place and the fabric manages sweat. A longer inseam can help reduce ride-up during squats or running. A shaped pouch can add support. Avoid loose cotton cuts if they stay damp or bunch under your shorts.
Is bamboo underwear good for the gym?
Bamboo underwear can work well in the gym because it feels soft and has a natural moisture-wicking claim. It also gives shoppers a material-based sustainability angle. During very sweaty sessions, some bamboo fabrics may feel wetter than thin synthetic fabric, so match the pair to your training intensity.
How do I stop underwear from riding up when I work out?
To stop underwear from riding up when you work out, choose a longer leg with a firm but comfortable opening. The garment should fit close to the thigh without squeezing. A stretch panel or ride-up-resistant design can help. If the legs still move, try a different inseam or size rather than tightening the waistband.
Should workout underwear have a pouch?
Workout underwear should have a pouch if you want more space and front support during movement. An anatomical or hammock pouch can keep the scrotum away from the inner thigh and reduce pressure from flat seams. It is not essential for every man, but it is worth trying if you adjust your underwear during training.
