Ever wished you could bottle high-altitude air and bring it to your local gym? Altitude training masks promise a shortcut — or at least a training tool — to help breathing muscles work harder, potentially improving endurance and respiratory efficiency. If you’re shopping for one in the US, you’ll find everything from budget-friendly options to pro-level gear. In this guide I’ll walk you through what these masks do, where to buy them, how to choose the right model, and how to use one safely so you get results without surprises.
An altitude training mask is a wearable device designed to restrict airflow to some degree so your lungs and breathing muscles have to work harder. Think of it like weight training for your diaphragm and intercostal muscles. Instead of lifting plates, you’re dialing in resistance to the air you breathe during workouts. Many models include adjustable valves to change resistance levels, and they come in a range of fits and materials.
Here’s the honest view: these masks do not actually change the oxygen concentration of the air the way a real high-altitude environment does. They increase breathing resistance and can simulate the sensation of reduced airflow, which challenges the respiratory system. That can improve respiratory muscle strength and breathing efficiency, but it won’t create the same blood-level adaptations (like increased red blood cell count) you’d get from weeks living at 8,000 feet or higher. So, use them as a training tool rather than a miracle shortcut.
Where you buy a training mask matters. Some retailers offer wide selections and fast shipping, others specialize in pro gear and expert advice. Below are reputable US stores where athletes commonly find altitude training masks and related breathing trainers.
Amazon is often the first stop for many buyers because of its vast selection. You’ll find multiple brands, customer reviews, and a range of price points from under $40 to well over $100. The big benefit is choice — you can compare models, read user feedback, and sometimes score fast shipping if you’re in a hurry. Just be sure to buy from reputable sellers and check model numbers carefully.
Dick’s is a national chain that carries gear for runners, cross-fitters, and general fitness enthusiasts. Their selection usually includes popular training mask brands and mid-range models. If you prefer trying a product in person or picking it up locally, Dick’s can be a convenient option. Staff at larger stores may also be able to point you toward related breathing trainers and accessories.
REI is a good choice if you want higher-end fitness gear and expert advice. While REI focuses on outdoor sports, they occasionally carry durable training masks and respiratory trainers suitable for endurance athletes. If you’re planning altitude trips or combining mask work with outdoor training, REI’s knowledgeable staff and member reviews can help you pick a model that fits your goals.
Rogue is the go-to for serious strength and conditioning equipment. Their selection may skew toward heavy-duty, performance-first models and accessories. If your training includes intense intervals or functional fitness, Rogue’s lineup often includes rugged masks built for regular, hard use. Expect professional-grade designs and equipment that pairs well with gym-based training.
Walmart carries budget-friendly training masks and entry-level models from a variety of brands. It’s a practical place to start if you want to test the concept without a big investment. You might not find the latest pro models, but Walmart’s price point options make it easier to experiment and learn what resistance level works for you before upgrading.
Academy is another national sporting goods chain with a mix of entry-level and mid-range training masks. Their stores often carry masks aimed at runners and amateur athletes, and online inventory can add more choices. If you want a balance between price, selection, and occasional in-store assistance, Academy is worth checking out.
Specialty fitness retailers like Perform Better and Power Systems focus on performance equipment used by trainers and gyms. They stock models that emphasize durability, adjustability, and clinical-grade build — ideal if you’re a coach or a serious athlete looking for professional features. Expect higher price tags but greater attention to build quality and replacement parts.
If you’re on a tight budget or hunting for a discontinued model, eBay and other secondhand marketplaces can be useful. Take care to inspect seller ratings and item photos, and ask questions about condition and parts like valves and straps. Buying used is a gamble, but it can pay off if you’re willing to inspect the item on delivery.
Choosing a mask is part practical and part personal preference. Think about how you train, your budget, and whether you want something you can wear every session or just for occasional use. Below are the most important factors to consider.
Fit is everything. A mask should seal comfortably against your face without pinching. Look for adjustable straps and soft silicone edges that don’t dig into skin. Many brands list measurements; use a tape measure in inches to check your face width and nose-to-chin length if they provide sizing charts. A poorly fitted mask can leak air and defeat the purpose.
Some masks offer multiple resistance settings via interchangeable valves or a dial. If you’re new, start with low resistance and build up. Adjustable masks give you flexibility to use the same device for light recovery days and for high-intensity intervals. This is especially handy if multiple people will use the same mask for different training goals.
Durable masks use medical-grade silicone, reinforced straps, and sturdy valves. If you train daily, look for models advertised for “heavy use” and read reviews about valve longevity. Strong stitching and quality attachment points mean fewer surprises — and fewer replacements — down the line.
Wondering how to work the mask into real training? Start slow and build the habit. Here are examples and a few rules of thumb.
Start with a light resistance and a 5-minute warm-up without the mask. Put the mask on for 10–15 minutes of easy jogging, stationary biking, or rowing at conversational pace. Finish with 5–10 minutes of cooldown and remove the mask. The goal is to get your breathing muscles accustomed to resistance, not to max out your heart rate immediately.
After a thorough warm-up without the mask, use moderate resistance for a set of intervals: 3 minutes hard (about 8 out of 10 effort) followed by 3 minutes easy, repeat 4–6 times. Finish with a cooldown. Intervals with a mask increase respiratory demand and simulate higher perceived intensity. Track progress by how quickly you can maintain effort at each resistance level.
Training masks are not for everyone. If you have asthma, chronic obstructive pulmonary disease, heart conditions, or any respiratory illness, check with a medical professional before trying one. Also, don’t use masks during activities where interrupted breathing could be dangerous — think heavy lifting if it causes dizziness, or technical climbs where balance is critical. Always listen to your body and stop if you feel lightheaded, faint, or unusually short of breath.
Take care of the valves, straps, and mask body to avoid odors and leaks. Wipe down silicone parts after each use, let them air-dry in a shaded spot, and replace valves if they lose flexibility. Many manufacturers recommend occasional deep cleaning with mild soap and warm water; just be sure to let parts fully dry before reassembling. Proper care keeps performance consistent and extends the lifespan of your investment.
If you’re after altitude-like adaptations, consider these alternatives: altitude tents and chambers (used for sleep or prolonged exposure), training camps at higher elevations, or structured breathwork and respiratory muscle trainers that use targeted resistance in a smaller, more controlled device. Each option carries trade-offs in cost, convenience, and effectiveness.
Entry-level models are often available for around $30–$60, mid-range masks fall in the $60–$120 range, and top-tier, pro-focused models can exceed $150. Specialty retailers and pro-grade brands tend to sit at the higher end. If you’re new to mask training, consider starting with a mid-range option. It’s a sensible balance between build quality and price while you experiment with how much benefit you actually feel.
Here’s a short way to pick a retailer: want the largest selection and fast shipping? Try Amazon. Prefer to see gear in person? Check Dick’s or Academy. Want pro-grade options and accessories? Rogue or specialty retailers like Perform Better and Power Systems are smart bets. Budget-conscious and testing the waters? Walmart or secondhand marketplaces may be the fastest route.
Altitude training masks are a practical tool for athletes who want to challenge their breathing muscles and add a new stimulus to their training. They’re not a miracle cure for aerobic fitness, but when used properly they can support respiratory strength, endurance, and mental toughness. Shop smart: assess fit, adjustability, and build quality, and pick a retailer that suits your preference for selection, price, and support. Start light, be safe, and treat the mask as one useful tool in a broader training toolbox.
