If you want pajama pants that move with you, wash well, and still look put-together when you step out of the house, the This Is J Pajama Pant in Black is worth a close look. Built from viscose from bamboo and designed in Canada, these are more than basic sleepwear — they’re a loungewear staple for anyone who prioritizes comfort without giving up style.
The This Is J Pajama Pant is a long, flowy pajama pant with a wide drawstring waistband that lets you adjust the fit. It’s marketed as a mix-and-match staple for loungewear and pajamas, made from 93% viscose from bamboo and 7% spandex. The result is a soft, slightly stretchy pant that drapes well and is machine washable and dryer friendly.
Key specs at a glance
Viscose from bamboo is the headline feature. It feels silky against the skin, breathes better than many synthetic materials, and keeps a relaxed drape. In practical terms, that means the pants stay comfortable whether you’re sleeping, working from home, or grabbing coffee.
The wide drawstring waistband lies flat and offers a customizable fit. If your waist fluctuates or you prefer different fits for lounging versus sleeping, the drawstring gives you control without bulk.
The pant’s flowy cut prevents clinging and creates a flattering line on most body types. It’s easy to move in and pairs well with a tank, tee, or matching pajama top for a coordinated set.
These pants are low-maintenance: toss them in the machine and the dryer. They keep their softness and shape with regular washing, which is ideal for everyday loungewear.
Manufactured in Canada with fabric patterns exclusive to This Is J, these pants have a thoughtful finish and consistent sizing. If you prefer products manufactured locally (or closer to home), this is a plus.
The brand offers a clear size range and helpful mapping for common sizes. Below is a simple guide that reflects This Is J’s size notes:
| Size | Typical fit (This Is J) |
| XS | 0–2 |
| S | 0/2–4/6 |
| M | 6–8/10 |
| L | 10–12/14 |
| XL | 14–16/18 |
