1. SLY Collective Underwear
SLY Collective Underwear has carved out a unique niche by fusing high-performance functionality with a bold, street-style aesthetic and a strong commitment to sustainability. This proudly Australian-made brand excels in creating what many consider to be the best running underwear for men who demand support, comfort, and chafe-free performance. Their approach combines innovative fabric technology with a design that addresses the most common frustrations runners face, from overheating to ride-up, making them a standout choice for both elite athletes and daily joggers.
The brand's core strength lies in its meticulously engineered design and material choices. By leveraging the natural properties of bamboo, SLY Collective delivers a product that is not only exceptionally soft but also highly functional. The fabric’s inherent moisture-wicking and quick-drying capabilities are essential for keeping you dry and comfortable during intense runs, while its natural antibacterial properties help manage odour.
Key Features and Performance Benefits
What truly sets SLY Collective apart is its signature inner hammock pouch. This clever internal structure provides exceptional scrotal support and separation, a critical feature for preventing the skin-on-skin friction that leads to painful chafing. This design also promotes better air circulation, helping to regulate temperature and reduce overheating, which is not only crucial for comfort but also beneficial for men concerned with reproductive health.
Expert Tip: For maximum benefit, ensure you select the correct size. The hammock pouch is designed to fit snugly, providing optimal separation and support. SLY Collective’s free size exchange policy makes it easy to find your perfect fit without risk.
The longer leg cut is another thoughtful feature, specifically designed to combat the annoying and distracting issue of ride-up. This ensures the briefs stay securely in place, whether you're sprinting, tackling hills, or on a long-distance trail run. Adding to its versatility, a discreet built-in stash pocket provides secure storage for a key or card, making it ideal for minimalist runs or travel.
Why It Stands Out
SLY Collective masterfully combines practical performance with a distinct identity. Their urban, graffiti-inspired graphics appeal to a younger, style-conscious demographic, while their transparent commitment to pesticide-free materials and ethical manufacturing resonates with eco-conscious consumers. Although they occupy a premium price point, the durability, comfort, and specialised features offer excellent value. The brand stands behind its quality with a comfort guarantee, offering a full refund on your first pair if you're not satisfied.
Pros:
- Innovative inner hammock prevents chafing and overheating.
- Pesticide-free bamboo fabric is moisture-wicking, antibacterial, and sustainable.
- Longer leg design prevents ride-up during activity.
- Built-in stash pocket for securing small valuables.
- Proudly Australian made with a comfort guarantee and free size exchanges.
Cons:
- Premium price point may be higher than conventional brands.
- Primarily available in Australia, which may affect international shipping options.

Here’s a breakdown of what makes their products unique:

3. Step One
Step One is a popular online brand that has carved out a significant niche in the comfort-first underwear market, making it an excellent destination for runners seeking relief from chafing. While not exclusively a running brand, their design philosophy directly addresses the friction and discomfort that plague many athletes. The platform’s main draw is its innovative use of bamboo viscose and specialised anti-chafe technology, making their boxer briefs a strong contender for the best running underwear for daily training and long-distance efforts.
The website is modern and user-centric, clearly communicating the benefits of its products through bold graphics and glowing customer testimonials. With over 30,000 five-star reviews, social proof is front and centre, building confidence for new buyers. The shopping experience is streamlined, guiding users directly toward their flagship boxer briefs for men and women.
Key Features and Offerings
Step One's main differentiator is their proprietary anti-chafe technology combined with exceptionally soft, sustainable fabric. Their boxer briefs are engineered with a specific goal: to stop your thighs from rubbing together uncomfortably. This makes them a favourite among runners who have struggled with irritation on longer runs.

Pro Tip: Take advantage of the First Pair Guarantee. If you are unsure about sizing or comfort, you can try your first pair and receive a full refund or exchange if it doesn't meet your expectations, without needing to return it. This removes any risk from your initial purchase.
Navigating the Step One Experience
Shopping on Step One is remarkably simple. The site primarily focuses on its core boxer brief products, though it also offers women’s styles and some apparel. A key benefit for Australian customers is the offer of free shipping on all orders, regardless of the value. While their products come at a premium price point compared to standard cotton underwear, the brand's focus on high-tech materials and chafe prevention offers clear value. Their primary drawback for some runners may be the limited selection, as they specialise almost exclusively in boxer brief styles.

Sportitude is a comprehensive Australian online retailer that caters to athletes across various disciplines, offering a curated selection of some of the best running underwear on the market.

Customer service is local, which is a significant advantage for handling any queries or returns.

6. VANTA Australia
VANTA Australia carves out a specific niche in the market by focusing entirely on high-performance men's underwear with its specialised Sweat Series. Designed by runners with the harsh Australian climate in mind, the brand’s mission is to deliver underwear that solves the most common issues faced by active men: chafing, riding up, and excessive sweat. This dedication to creating the best running underwear for men makes VANTA a compelling choice for athletes seeking ultimate comfort and support.
The brand's website and informational pages are direct and performance-oriented, centring on the technical aspects of their products. Instead of a broad catalogue, VANTA concentrates on perfecting its core offering, ensuring that every pair of boxer briefs meets rigorous standards for athletic use.
Key Features and Offerings
VANTA's Sweat Series is engineered from the ground up to enhance the running experience, particularly in hot and humid conditions. The key is a combination of advanced fabric technology and an ergonomic design that moves with the body, not against it. The brand’s claim of a "no ride-up" fit is a major drawcard, addressing a persistent annoyance for many runners.

Final Stride: Choosing Your Ultimate Running Companion
Navigating the extensive world of performance apparel can feel as gruelling as the final kilometre of a marathon. However, this detailed exploration of the best running underwear available in Australia has equipped you with the knowledge to make a confident and informed decision. We've dissected everything from the technical marvels of moisture-wicking fabrics and the crucial importance of anti-chafe construction to the specific benefits of pouch designs and sustainable materials. The journey to finding your perfect pair isn't about a single "best" option, but about finding the pair that best aligns with your unique anatomy, running style, and personal values.
Remember, the right underwear is the unsung hero of your running kit. It's a foundational layer that can prevent painful chafing, manage sweat to keep you dry and comfortable, and provide the precise level of support you need to move with freedom and focus. As we've seen, brands like Runderwear Australia and 2XU are masters of technical compression and seamless design, while Step One focuses squarely on eliminating thigh chafe for a broader range of activities. Retailers such as Running Warehouse Australia and Sportitude offer a curated selection, allowing you to compare and contrast various specialised brands under one roof.
Your Personalised Buying Guide
To crystallise your decision, let’s revisit the core factors. Your choice should be a deliberate one, guided by your specific requirements. Before you make your final selection, consider these key questions:
- What is my primary running challenge? If debilitating thigh chafing is your main concern, a brand like Step One with its UltraGlyde™ panels is a strong contender. If you need maximum support and moisture control for high-intensity racing, the technical compression fabrics from 2XU or the seamless designs from Runderwear are likely your best bet.
- How important are sustainability and local support? For the eco-conscious runner who prioritises Australian-made quality, brands like VANTA Australia and SLY Collective Underwear stand out. Their commitment to sustainable materials like bamboo and support for local manufacturing offers a purchase you can feel good about.
- What is my budget and buying preference? If you're looking for value and prefer to buy in bulk, multi-pack options can be a cost-effective strategy. Conversely, if you view your running underwear as a long-term technical investment, a premium, single-pair purchase from a specialised brand might offer better performance and durability over time.
- Do I need multi-purpose functionality? Think about your lifestyle beyond the running track. If you're a frequent traveller, a design with a secure pocket could be invaluable. If you value all-day comfort that transitions from a morning run to a day at the office, the soft, breathable fabrics and supportive pouches offered by brands like SLY Collective Underwear are an excellent choice.
Ultimately, selecting the best running underwear is an investment in your comfort, performance, and overall enjoyment of the sport. By moving beyond generic cotton boxers and embracing purpose-built gear, you eliminate a major source of potential distraction and discomfort. This allows you to focus purely on your stride, your breathing, and the simple joy of the run.
For a perfect blend of high-performance functionality, exceptional comfort, and bold Australian design, explore the collection at SLY Collective Underwear. Their innovative pouch design and use of sustainable bamboo fabric make them an outstanding choice for both dedicated runs and all-day active wear. Discover your perfect fit and upgrade your foundational layer at SLY Collective Underwear.
