Lasting Adam Men’s Polypro Boxers Review

Material

The Lasting Adam boxers are made of polypropylene with a small content of elastane fibers (3%). When I unpacked them, I immediately noticed that the fabric is somewhat thicker than the fabric of my other hiking boxers which are made of polyester, nylon or Merino wool. Polypropylene is in general a denser fiber and at first, I was a bit worried that the boxers would be too warm for summer. Nevertheless, my worries proved unnecessary. The fabric is not warm, and I was satisfied with the Lasting boxers also in the heat of the summer.

I started testing the Adam boxers in the spring and I focused on the breathability, moisture management, drying time and odor resistance of the material. These are in my opinion the most important qualities when it comes to underwear for hiking and other aerobic sports. The first thing I noticed when wearing the boxers for hiking was that they absorb very little moisture. The moisture mostly passes through the fabric and thus the boxers also dry extremely fast. The rapid drying time is indeed the main benefit of polypropylene and the reason why it’s used in sportswear. If you want to learn more about polypropylene as a material, read this article from Sewport while I recommend you to check out my article Why you should wear quick drying clothes for hiking if you want to know why drying time matters.

Now, in terms of moisture-wicking properties the boxers don’t pull the moisture from the skin as efficiently as Merino wool, but that’s to be expected: If the fabric doesn’t absorb moisture it also can’t pull it from the skin. I don’t consider this a downside but rather a tradeoff. The boxers also provide decent breathability – not as good as thin polyester and Merino boxers, but I didn’t encounter any problems while wearing them for hiking and running.

The Lasting Adam boxers have a silver-ion antimicrobial treatment which in simple terms means that the fabric is infused with silver. Silver kills odor-causing bacteria and thus makes these boxers odor-resistant. I can confirm that the boxers didn’t become smelly even if after having worn them for multiple activities without washing them in between. So far, the antimicrobial treatment hasn’t washed out, which is often the case with such treatments. So, all in all I’m very satisfied with odor resistance.

Comfort, fit, sizing and functionality

The Lasting Adam boxers have an inseam length of two inches (5 cm) and thus belong in the short leg boxer briefs category. They have a seamless design which means that there are no seams on the sides, back or front. Nevertheless, there are seams along the elastic waistband and the crotch gusset. As these seams are flatlock seams, chafing is unlikely although the latter is placed in one of most sensitive places. I haven’t encountered any chafing or other discomfort during the testing period.

The boxers are designed to fit tightly to the body and the material is very stretchy. They are available in four different sizes: XXS/XS, S/M, L/XL and 2XL/3XL. I got the boxers in size L/XL but unfortunately, they are a bit too large for me. According to Lasting’s size guide I should have picked size S/M, but I never had underwear smaller than size L and thus I decided to go with L/XL. That was obviously a mistake but as long as you stick to their size guide, you should be okay choosing the right size.

The logo and labels are printed for extra comfort and the boxers don’t have a fly. I don’t think this is a problem as I rarely use the fly. I also find the concept of a fly to be a weak link as it requires more stitching (which can break if you actually use the fly), that again makes the underwear heavier and can be the cause of chafing.

Washing and drying

The Lasting Adam boxers should be machine washed at 30 C without additives such as bleach or softeners. Since they are made of synthetic fibers, they also shouldn’t be tumble dried. Nevertheless, as the underwear absorbs almost no water, it would be silly to waste time and energy to tumble-dry them. Since the boxers have an antimicrobial treatment, they also don’t have to be washed as frequently as other underwear.
