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.

08-03-2026These undies are vivid colors, and very nice quality in terms of thickness and stitching. They fit as expected in terms of size, but be advised they come very high on the torso, in part because of a wider than normal waist band. My son is short so this made them bunch up a bit as they sat at his natural waist, but he seems to think they are just fine so I let it be.The only reason I deducted one star was because of the horrible smell they came with. I am usually the mom who rolls her eyes at the hysteria a lot of people display concerning any faint odor from new clothes, but this time it really was BAD. They were clearly saturated with some sort of chemical. It took literally three washings for the smell to wear off enough that I felt comfortable giving them to him (although on the other hand, they got very soft! Color faded a fraction, but not enough to really change the look). If you wash these a couple of times before giving them to your child, it should be ok. But I have never experienced any new clothes smell this bad.

08-03-2026Very soft with good thickness. My son says they are comfy. After reading reviews I went a size up in case. For reference, my 4 y/o is about 36lbs & 40 in. Got the small which seem to fit with some room to grow.

08-03-2026Originally 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:)

08-03-2026These are excellent boys underwear: soft, colorful, wash well and 100% cotton. My son is really enjoying his new underwear. They are easily comparable to more expensive Venait Baby briefs, which we've previously had and my son liked. As the point of comparison, the fabric on these briefs feels as soft as the Venait Baby ones, although the band is slightly less soft, but it's still definitely not scratchy. My son is fairly sensitive to the feel of his clothes, and he has no complaints about these briefs at all. I'm hoping they'll last as well as the Venait baby ones lasted us, which my son grew out of before they lost any color or had any other blemishes.Overall, these Trimfit Boys Briefs are a great value for the price, and I'm definitely planning on buying them again. I love that they come in solids and stripes, rather than having cartoon characters on them.These days it seems most reviews are written by those who got the product for free for a review, so I feel the need to add that I didn't receive any discounts and bought it here on amazon for full price.

08-03-2026I always buy these for my son, who has a slim build. These fit him well and come in fun (but not too baby-ish) colors. And no bothersome tag! The colors wear well and the fabric holds up to lots of washing.

08-03-2026Es 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

08-03-2026Here'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.
