Premium Materials & Construction
We build every piece of Mossimo underwear with carefully selected fabrics that prioritize comfort and durability. Our essential cotton styles use 100% premium cotton that’s pre-shrunk and colorfast, while our performance line features advanced moisture-wicking blends.
Each garment undergoes rigorous quality testing to ensure the elastic waistbands maintain their stretch and the seams withstand repeated washing. The tagless construction across our entire mossimo underwear collection eliminates scratchy labels that can cause irritation during long days.
Sizing & Fit Guide
Finding the right fit starts with measuring your waist at its natural point, typically just above your hip bones. Our sizing runs true to standard US measurements, with Small fitting 28-30 inch waists up to XXL for 42-44 inch waists.
Rise Options
We offer multiple rise options to match your preference: our briefs feature a classic mid-rise, while boxer briefs provide slightly lower coverage. The performance styles include compression zones that provide support without feeling restrictive.
Care Instructions
Proper care extends the life of your mossimo underwear significantly. Machine wash in cold water with like colors using a gentle cycle to preserve the fabric integrity and elastic performance.
Avoid fabric softeners on performance styles as they can reduce moisture-wicking properties. Tumble dry on low heat or line dry to prevent shrinkage and maintain the shape of elastic waistbands. The cotton styles become softer with each wash while maintaining their fit.
Multi-Pack Value Options
Stock up and save with our convenient multi-pack options available across the entire collection. Choose from 3-packs, 5-packs, or 7-packs to ensure you always have fresh, comfortable underwear ready.
Mix and match different styles within multi-packs to discover your preferences, or stick with your favorites for consistent comfort. Our multi-pack pricing delivers significant savings compared to individual purchases while ensuring you’re never caught without quality essentials.
Mossimo Underwear Questions
Our mossimo underwear follows standard US sizing and typically runs true to size. If you wear a Medium in most underwear brands, our Medium should fit comfortably. We recommend checking our size chart if you're between sizes or prefer a looser fit.
The cotton styles prioritize breathable comfort for everyday wear, while performance styles feature moisture-wicking technology for active lifestyles. Performance boxer briefs also include compression fit and anti-chafe seaming that cotton styles don't have.
Our elastic waistbands are designed to maintain their stretch through regular washing and wearing. Following the care instructions and avoiding high heat during drying helps preserve elasticity for the longest possible lifespan.
Currently our multi-packs contain the same size across all pieces in the pack. This ensures consistent fit and makes reordering your preferred size simple when you need to restock your underwear drawer.
We accept returns on complete multi-packs within 30 days of purchase. Individual pieces cannot be returned separately, but if there's a quality issue with one item, we'll replace the entire pack to ensure your satisfaction.
Replace mossimo underwear when you notice the elastic losing its stretch, fabric becoming thin, or seams showing wear. With proper care, our quality construction typically provides 12-18 months of regular wear before replacement is needed.
Absolutely. The performance boxer briefs work excellently for everyday wear, especially if you prefer compression fit or deal with chafing. The moisture-wicking properties also help during hot weather or long days at the office.
