Perfect Lounge Pants
Size: 4X-Large, Color: Black Heather, Number of Items: 1
These pants are so soft and comfortable for wearing around the house. Light enough for wear during the summer and for layering in cooler temperatures. They stretch in all the right places for a very comfortable fit and are well made. Would definitely buy again.

Soft and Comfortable Lounge Pants
Size: Large, Color: Black, Number of Items: 1
These sweatpants are soft, comfortable, and great for lounging around the house or running quick errands. The fleece lining adds warmth without feeling too heavy, and the elastic bottoms give them a nice fit. The pockets are a great addition and are deep enough to hold everyday essentials. The fit was true to size, and they've held up well through multiple washes. A comfortable pair of sweatpants for everyday wear.

Material quality getting worse.
Size: 3X-Large, Color: Navy, Number of Items: 1
Our household has been buying Fruit of the Loom sweatpants for at least 15 years. So I ordered these this year. Yes, they're soft, comfortable and fit right, and good price. But after only 3 wearings, the material began to pill. I checked my older pairs, which have never pilled. The oldest are a 50-50 blend, the ones bought 2 years ago are 45 cotton, 55 polyester. The new ones are 40 cotton, 60 polyester. So I guess that's the difference. I don't expect them to last as long. Sorry, FOTL, you could have gotten a 5 star rating from me if you hadn't skimped on the material.

Perfect Fit for My 370 lb son. Soft, Durable, No Shrinking, Incredibly Comfortable!
Size: 4X-Large, Color: Black Heather, Number of Items: 1
I can’t speak highly enough about these Fruit of the Loom Eversoft Fleece Elastic Bottom Sweatpants. I purchased them for my 370 lb family member, who wears a 4X, and these are truly the only pants I’ve ever seen him feel completely comfortable in. They look great too and have pockets! Shopping for someone of his size has always been a challenge, especially finding pants that don’t dig in, feel soft, and hold up over time. His weight pools mostly around his waist and ankles, making it even harder to find something that fits without being tight or restrictive in those areas. But these sweatpants? Absolute perfection. The material is made from 60% cotton and 40% polyester fleece, which creates this super soft, cozy texture on the inside, while the outside has a smooth, durable finish. The Eversoft technology really delivers on comfort—no scratchy feeling, just a nice, breathable fabric that keeps him warm without overheating. One of the biggest selling points for us is that they do not dig into the waist or ankles at all—which, again, is so important for someone whose weight is concentrated in those areas. The waistband is wide, stretchy, and soft with a functional drawstring, so it adjusts without pinching or feeling tight. The elastic at the ankles has enough give to keep the pants in place without constricting, even with larger ankles. That’s rare to find in extended sizes where elastic bands can often be too tight and uncomfortable. We’ve washed these multiple times (always following the care instructions—cold water, gentle cycle, and tumble dry low), and they have not shrunk or lost their shape. The fleece stays soft, the seams hold up, and there’s no pilling or fading so far. Another bonus: no foul odor when they arrive (which I’ve experienced with other brands in the past). They come fresh and ready to wear right out of the bag. I’ve already ordered more pairs because these are the only pants my family member wants to wear while working on stabilizing his thyroid condition and managing his weight. They give him comfort, dignity, and confidence, which is priceless. If you have a larger family member, or you’re someone with similar sizing needs, do not hesitate to try these. They check every box: softness, fit, durability, easy care, and true comfort where it matters most. Thank you, Fruit of the Loom, for making inclusive, thoughtful clothing that truly accommodates real bodies. These sweatpants have made a real difference in my family member’s daily comfort.
