Trimfit was established in 1921 by Arnold, Harry and Robert Kramer. The brothers worked in a family-owned store in Manhattan, and saw an opportunity to wholesale hosiery to merchants in New York. The 1930s also marked an important event in Trimfit's history, as the company was invited to source and sell Shirley Temple socks. This product catapulted the company to a new level of sales and profitability. At this time, the Kramer brothers studied apparel manufacturing and assumed control of a textile factory in Philadelphia, which allowed them to produce and manufacture their own hosiery. 1949, Trimfit opened a state-of-the-art manufacturing facility in North Carolina. Soon after, the brothers purchased a manufacturing facility in Canada and began manufacturing and selling its products to Canadian customers. Today, our assortment includes underwear, t-shirts, training pants, slippers, footwear, thermals, sleepwear and much more! Trimfit’s broad range of sizes for girls and boys aged 0 to 18, provides comfort, quality, and ease at a value unmatched by other brands. Trimfit designs their clothing and apparel by adjusting to the needs of children. Having comfortable and dependable clothing not only makes your children happier but offers parents relief in knowing their children are well prepared for any scenario.

They are comfortable and wear well. The quality is good, breathable and look great. My only complaint is they are small too size.

These underwear are incredibly comfy and have been a perfect choice for my son! The cotton material is soft, breathable, and gentle on his skin, which is important for all-day comfort. The tagless design eliminates any irritation, and the waistband is stretchy yet snug, so it stays in place without digging in. My son loves how comfortable they feel, and I appreciate how well they hold up after multiple washes—no shrinkage or fading. The 8-pack offers great value, and the fit is just right. These briefs are a fantastic, practical option for active kids. Highly recommend!

Es la primera de varias compras qué haré de ellos... La tela agradable, resistente al igual que las costuras, tras varias lavadas sigue el color. .. Los resortes son muy cómodos para los peques, este es el tema con el que más batallo en compras en línea, pero en este caso nos fue genial... Leí sobre las tallas, la verdad es que a mi peque fue la talla correcta... Los recomiendo bastante

Here's our second pack of Trimfit Boys Soft 100% Cotton Tagless Briefs Underwear, and we couldn't be happier. The last set we bought was outgrown, but it held up remarkably well over time. One of the biggest issues we've noticed with other brands is that they tend to get baggy and then his penis comes out the side. However, with Trimfit, that's never been a problem; these briefs maintain their shape and provide consistent support. They're not only comfortable due to the soft cotton material but also practical for active little ones. Highly recommend for any parent looking for durable, reliable underwear for their child.

I bought the Trimfit Boys Soft 100% Cotton Tagless Briefs for my son, and they have exceeded my expectations in every way! The cotton material is incredibly soft, which is perfect for all-day comfort, especially for kids who are constantly on the move. My son has sensitive skin, and these briefs keep him comfortable without any irritation.The tagless design is a huge bonus—no annoying tags to scratch or bother him. The fit is true to size and holds up well throughout the day without any sagging or stretching. Even after multiple washes, the color and shape stay intact, which is rare for kids' underwear! We opted for the 16-pack, which has been a lifesaver. With the extra pairs, I don’t have to worry about running out between laundry days, and it’s honestly a fantastic value for the price.I highly recommend these briefs to any parent looking for comfortable, high-quality underwear for their kids. Trimfit has nailed it with these!

My son says that out of 10, these would be a 9. He really likes these 'grown-up' underpants. I like that they have lasted lots of washes, don't have characters, and fit well. I don't know if these are suitable for potty training, but they work for my 6yo who chooses these over any of his others. They run a TINY bit large, but I actually liked that.

Originally I was getting fruit of the loom for my almost 4 yr. old that has a 22" waist. I ordered x-small, small and x-small in an almost identical but different brand with the same quantity and price.This brand the x-small fit and thought I was keeping them until my son tried small. Not a huge difference making them lose anywhere, just enough to see they fit much better.The other brand fit as well but felt the material was a tad bit thinner and lose. Laying under the other x-small I was able to see the outline of these even though the size chart reads the same.The material, quality, price & color (black/no visible stains) is what will make me 💯 choose these again.I did try drying 1 pair and didn't notice any shrinkage, threads or fading so I'm happy finding these. My son's happy too cause they are comfortable and likes they are solid in color making him feel more grown up:)

Good quality for the price, don’t shrink after washing and drying. A little bit to long for my 3 and a half years old boy. But it is the good size for the waist. My son very like them and he is proud to wearing them!
