Flint and Tinder Sweatpants | Premium American-Made Fleece

★★★★★4.8/5· thousands of reviews

We built these sweatpants to match the durability of our legendary 10-Year Hoodie. Heavyweight 13oz fleece feels substantial from the first wear — soft inside, durable outside, with a broken-in comfort that only gets better over time.

Cut with a modern athletic fit, they sit comfortably at the natural waist with a tapered leg that won’t bunch at the ankles. Reinforced stitching at stress points and a drawstring waistband you can actually tighten mean these sweatpants won’t lose their shape after countless washes. Made entirely in the USA from premium ring-spun cotton, they’re designed for guys who want comfort without compromise.

Premium American Fleece Construction

Premium American Fleece Construction

We source our heavyweight fleece from one of the last remaining textile mills in the Carolinas, where they’ve been spinning premium ring-spun cotton for over 80 years. The 13-ounce weight hits the sweet spot between cozy warmth and year-round wearability.

Ring-spun cotton creates longer, stronger fibers than standard open-end yarn, which means our Flint and Tinder sweatpants resist pilling and maintain their structure wash after wash. The brushed interior traps warmth without adding bulk, while the smooth exterior face stands up to daily wear. Every pair goes through a pre-shrinking process so the fit you buy is the fit you keep.


Sizing & Fit Guide

Sizing & Fit Guide

Our sweatpants run true to size with an athletic fit that’s trim through the hip and thigh without feeling restrictive. The tapered leg creates a modern silhouette that works with sneakers or boots.

We recommend ordering your usual pant size — the drawstring waistband provides plenty of adjustment range. If you’re between sizes or prefer a more relaxed fit, size up one. Inseam measures 30 inches on a size Medium, with proportional adjustments across the size run from Small to XXL.


Care Instructions for Long-Term Performance

Care Instructions for Long-Term Performance

Machine wash cold with like colors to preserve the fabric’s integrity and prevent unnecessary wear. We recommend turning the sweatpants inside out before washing to protect the outer face and maintain color depth.

Tumble dry on low heat or hang dry to extend the life of the elastic and drawstring. High heat can damage the cotton fibers over time and cause premature fading. The pre-shrunk fleece means you won’t see significant size changes, but gentle drying keeps the brushed interior soft.

Best sweatpants I’ve ever owned
I bought these skeptical about the price, but after three months of near-daily wear, I get it. The fleece is thick but breathable, and they’ve kept their shape perfectly through weekly washing. Worth every dollar.

Finally found my perfect fit
The tapered leg is exactly what I’ve been looking for — not too skinny, not baggy at all. I’m 6’1″ and the large fits like they were tailored for me. The quality is immediately obvious when you hold them.

American-made quality shows
I’ve tried plenty of fleece sweatpants and these are in a different league. The weight and construction are serious, and knowing they’re made here makes me feel good about the purchase. They’re my new favorite pants.

Comfortable from day one
No break-in period needed with these. The brushed interior is soft right out of the package, but the outside still looks sharp. I wear them around the house and out to coffee without feeling sloppy.

Holds up to constant use
I work from home and basically live in these. Six months in and they look almost new — no pilling, no stretched-out waistband, no fading. The reinforced stitching is legit. These will last years.

Warmer than expected in a good way
The 13oz fleece is no joke. I bought these for lounging but they’ve become my go-to for cold morning dog walks. They block wind better than I thought sweatpants could while still being breathable indoors.

Sweatpants Questions — Sizing, Fit & Care

Our sweatpants run true to size with an athletic fit that’s trimmer than traditional lounge styles but roomier than performance joggers. The tapered leg creates a modern silhouette without feeling tight.

If you typically wear a 32-inch waist in jeans, order a Medium. The drawstring provides several inches of adjustment in either direction. Guys who prefer a relaxed fit or are between sizes should order up one size.

Most mall-brand sweatpants use 8-10oz fleece that feels thin and loses shape quickly. Our 13oz heavyweight fleece is substantially thicker and more durable, with a tighter knit that resists pilling.

The extra weight provides better insulation and wind resistance while maintaining breathability. Ring-spun cotton construction creates longer, stronger fibers that hold up to repeated washing without breaking down or fading like cheaper open-end yarns.

No significant shrinkage — we pre-shrink the fleece during manufacturing so the fit remains consistent through dozens of wash cycles. You might see 1-2% relaxation in length after the first wash as the fabric settles, but nothing that changes the fit.

To maintain the original dimensions, wash cold and tumble dry on low heat or hang dry. High heat can cause minor shrinkage over time and may damage the elastic waistband support.

Yes, every step happens domestically — from spinning the cotton yarn in the Carolinas to cutting and sewing the final garment in Los Angeles. We work with American factories that maintain fair labor standards and quality control you won’t find in overseas production.

The higher cost reflects living wages for skilled workers and premium domestic materials. When you buy these sweatpants, you’re supporting American manufacturing jobs and getting construction quality that offshore production can’t match at any price point.

The 13oz fleece provides substantial warmth for fall and winter wear in most climates. They’re comfortable down to freezing temperatures for moderate outdoor activity like walking the dog or running errands.

The brushed interior traps body heat while the tight-knit exterior blocks wind better than thinner fleece. They’re not insulated winter pants, but they offer significantly more warmth than standard 8-10oz sweatpants. Many customers wear them as a comfortable base layer under shell pants for extreme cold.

Absolutely — the athletic fit and articulated knees provide full range of motion for squats, lunges, and stretching. The tapered leg won’t catch on equipment or bunch up during floor work.

The heavyweight fleece is more insulating than dedicated performance fabrics, so they’re better suited for strength training or cool-weather outdoor runs rather than high-intensity cardio. The cotton absorbs moisture rather than wicking it away, which some guys prefer for lifting sessions but isn’t ideal for hot yoga or intense spin classes.

The inseam measures 30 inches on a size Medium, with proportional adjustments across all sizes. Small has a 29-inch inseam, while XL and XXL extend to 31 inches to maintain proper proportions.

The rise is mid-level at approximately 11 inches on a Medium, designed to sit at your natural waist just below the navel. This is higher than low-rise joggers but not as high as vintage sweatpants, creating a modern fit that stays in place during movement without feeling restrictive.
