Get clear answers on how Smartouch Trunks should fit, what the viscose-elastane fabric feels like, and how to care for everyday trunk underwear.
Quick answer
Smartouch Trunks are designed to sit close to the body without feeling constricting, thanks to a soft viscose-elastane fabric and flat-bonded seams. Choose your usual size for a snug, flexible fit that stays comfortable through the day.
Why the fabric changes how trunks feel
The viscose-elastane blend in Smartouch Trunks gives a soft, supple handfeel with enough stretch to move with you. That combination matters because trunk underwear sits directly against the skin all day; a fabric that feels light and flexible reduces the chance of bunching or irritation. Unlike cotton, viscose tends to drape smoothly and dry quickly, but it also needs gentler washing to keep its softness.
Where flat-bonded seams make a difference
Smartouch Trunks use flat-bonded seams at the waistband and leg openings. This construction removes the bulky overlap you find on traditional stitched seams, so the edges lie flatter under trousers and reduce friction during movement. If you are sensitive to seam ridges or spend long days sitting, this detail is worth prioritizing over decorative features.
When trunks are the right choice—and when they are not
Trunks suit most everyday situations: office wear, commuting, and casual weekends. They provide more coverage than briefs but less leg length than boxer briefs, so they work well under slim or tailored trousers. However, if you prefer a looser feel or need extra thigh protection during intense activity, a longer boxer brief may be a better fit. Smartouch Trunks are not designed as compression wear, so do not expect firm support for high-impact sports.
Smartouch Trunks: your fit and care questions answered
- How should trunks fit?
- Trunks should sit close to the body with the waistband flat against your skin—snug enough to stay in place but not tight enough to leave marks. The leg openings should lie flat without riding up. If you are between sizes, consider sizing up for a more relaxed feel, since the viscose-elastane blend already provides stretch. Check for a smooth waistband and leg line before removing tags.
- What does the viscose-elastane fabric feel like?
- It feels soft, supple, and lightweight against the skin, with enough elasticity to move with you. Unlike cotton, it has a smoother, slightly cooler touch and dries faster after washing. Expect it to feel gentle even on warm days, though it may feel less breathable than open-weave cotton in extreme heat. Wash in cool water and avoid high heat to preserve the soft handfeel.
- Are flat-bonded seams durable?
- Flat-bonded seams are created by fusing fabric layers rather than stitching, which gives a smooth finish. They hold up well with normal wear and gentle washing, but avoid fabric softeners and high dryer heat, which can weaken the bond over time. Turn the trunks inside out before washing to reduce abrasion. Skip the fabric softener to extend seam life.
- How should I care for Smartouch Trunks?
- Machine wash cold on a gentle cycle with like colors, and tumble dry low or hang to dry. Do not bleach or iron directly on the seams. Following these steps keeps the viscose-elastane blend soft and the flat seams intact. Air-drying preserves elasticity longer than repeated dryer use.
- Can I wear trunks under slim trousers?
- Yes—the close-fitting cut and flat seams are designed to lie smooth under slim or tailored trousers. The short leg length prevents bunching, making them a practical choice for office wear or fitted jeans. Choose a color close to your trouser shade if you prefer extra discretion.
