How to Choose the Best Long Underwear for Men

To choose the best long undies, you’ll want to look at several factors. When we shortlisted our best options, the first thing on our minds was not the price but the performance instead. As a result, we were particularly interested in quality-related features. So, what were they? Let’s see them below!

Flexibility

When you’re looking to use long johns as sportswear or travel gear, you’ll want them to be super flexy and stretchable. That’s because you want freedom of movement, of course. We made sure of this feature by double-checking the specs as well as customer reviews.

Toughness

Whether you’ll be wearing long underpants as casual everyday wear or activewear for sports, it’s necessary that they are tough and sturdy. So, the key is to look at the fabric and manufacturer’s claims. Usually, wool and cotton are tougher than silk.

Is silk underwear good for men?

Silk is breathable and soft, making it a good undergarment choice. Also, it doesn’t trap moisture – keeping you dry and fresh all day!

Is silk underwear better than cotton?

Silk is usually softer and cooler than cotton, which makes it a great fit for underwear. Also, silk wicks off moisture, whereas cotton absorbs it, making you feel damp all day. However, cotton can be more resistant to the elements and last longer than thin silk.

Should men wear underwear to bed?

Experts recommend that men wear loose and roomy underwear to bed rather than a tight-fitting undergarment. Also, cotton underwear serves better compared to silk at night.
