When you're pushing through a grueling leg day or sprinting on a treadmill, your training gear shouldn't be the thing distracting you. Athletic Works Buttercore Shorts are engineered to solve common activewear headaches like chafing, riding up, and heavy moisture retention. Built with a buttery-soft polyester-spandex blend, these shorts provide lightweight coverage and free movement without breaking the bank.
If you're wondering whether these budget-friendly training shorts hold up against heavy sweat and high-impact movement, you're in the right place. Let's break down how they fit, what materials make them tick, and how they handle real gym conditions.
Understanding the Buttercore Fabric Technology
The defining feature of these shorts is the fabric. Traditional gym shorts often rely on stiff, coarse polyester that traps heat or feels abrasive against the skin during repetitive movements like running or cycling. Athletic Works takes a different approach by utilizing a peached or brushed microfiber knit.
This fabric undergoes a mechanical brushing process on the outer and inner faces. It creates a soft, matte finish that feels smooth to the touch rather than slick or plastic-like.
- Moisture management: The synthetic fibers pull sweat away from your skin toward the outer surface for rapid evaporation.
- Four-way stretch: Knit construction allows the material to stretch in every direction, accommodating deep squats and lunges without binding.
- Weight profile: The fabric is lightweight, meaning it won't weigh you down when soaked in sweat during a high-intensity interval session.
Fit, Sizing, and Silhouette Design
Finding gym shorts that fit your waist without squeezing your thighs can be frustrating. The Athletic Works Buttercore Shorts feature a tailored athletic cut that balances a secure waistband with a relaxed leg opening.
Most versions feature an elastic waistband paired with an internal drawstring. This setup lets you lock down the fit so the shorts don't sag during heavy barbell work or plyometric jumps.
- Inseam length: Typically hovering around 5 to 7 inches, the inseam hits well above the knee. This length prevents fabric from catching on your knees when you're deep in a squat or cycling.
- Rise: A mid-rise waist sits comfortably right at the hips, avoiding the discomfort of low-rise cuts or the bunching of high-waisted alternatives.
- Lining options: Depending on the specific style variation you pick up, some models include a soft moisture-wicking liner, while others are unlined shells designed to be paired with your preferred compression shorts.
Real-World Performance: Gym, Running, and Lounging
Gear specs only matter when you put them to the test. Here is how the Buttercore shorts perform across different active environments.
Strength Training and Cross-Training
During heavy lifts like deadlifts and squats, you need gear that stretches without tearing or pulling tight across your quads. The four-way stretch fabric shines here, allowing full depth without resistance. The flat-locked seams sit flat against your skin, eliminating the friction that causes chafing over long training blocks.
Running and Cardio Work
While they aren't dedicated racing split-shorts, they handle short-to-medium runs exceptionally well. The lightweight build prevents heat buildup around your hips. If you choose an unlined version, pairing them with a proper pair of athletic underwear keeps chafing at bay during long miles.
Recovery and Daily Wear
Because the brushed fabric feels exceptionally soft against the skin, these shorts double as comfortable loungewear. They don't look overly technical, making them easy to wear while running errands after a workout.
Common Mistakes When Choosing Activewear Shorts
Shoppers often make a few avoidable errors when picking up budget-friendly training gear. Keeping these pitfalls in mind will help you get the most out of your purchase:
- Ignoring the liner preference: Buying an unlined short when you prefer built-in support—or vice versa—leads to discomfort. Check the product tag or description before buying.
- Sizing down for compression: These shorts are designed with built-in stretch. Sizing down too far causes the waistband to dig in and stretches the fabric thin, making it prone to transparency under tension.
- Using fabric softener on synthetic blends: Washing polyester-spandex blends with fabric softener leaves a coating on the fibers, destroying their moisture-wicking capabilities and trapping odors. Wash them with standard detergent and tumble dry on low or air dry.

Frequently Asked Questions
Are Athletic Works Buttercore Shorts see-through when squatting?
No, the high-density knit fabric provides solid opacity even when stretched. However, if you size down too aggressively, stretching the fabric past its intended threshold can compromise coverage.
Do these shorts have zippered pockets?
Pocket configurations vary by style. Most options include deep side pockets suitable for keys or a locker key, but they typically lack zippers. If you need secure storage for a smartphone during a run, you may want to look for a specialized running short with a zip pocket.
How do I wash them to keep them soft?
Wash your shorts in cold water with similar synthetic fabrics. Skip the fabric softener entirely, as it breaks down the brushed texture and clogs the moisture-wicking pores. Air drying is best, but a low-heat tumble dry works fine too.
Can I swim in these shorts?
While the polyester blend dries quickly, they aren't designed as boardshorts or swim trunks. Chlorine and salt water will degrade the elastic fibers and the soft brushed finish much faster than standard sweat and gym washing.
