My Buying Guides on Square Cut Swim Trunks
When I first started looking for the perfect square cut swim trunks, I realized there are quite a few things to consider to get the best fit, style, and comfort. Here’s what I learned along the way that might help you find your ideal pair.
Understanding Square Cut Swim Trunks
Square cut swim trunks are a modern take on classic swimwear, characterized by their straight-cut legs and a fit that’s somewhere between briefs and board shorts. They offer a sleek, athletic look with more coverage than briefs but are less baggy than traditional trunks.
Fit and Comfort
For me, fit is everything. Square cut trunks should hug your body without feeling too tight or restrictive. I look for trunks with a bit of stretch so I can move freely, whether I’m swimming, playing beach volleyball, or just lounging. Checking the sizing chart carefully helps avoid surprises, and I often prefer trunks with an adjustable waistband or drawstring for a perfect fit.
Material Matters
The fabric plays a huge role in comfort and durability. I usually go for quick-drying, lightweight materials like polyester or nylon blends. These fabrics help me stay comfortable both in and out of the water. Some trunks also have a soft lining, which adds comfort and prevents irritation.
Style and Design
Square cut trunks come in a variety of colors and patterns. I like to pick a style that matches my personality—whether it’s bold prints or classic solid colors. Reflecting on where I’ll wear them also helps; for instance, a subtle design works better for family pools, while bright patterns are great for beach parties.
Features to Look For
- Pockets: Some square cut trunks come with pockets, which can be convenient but might add bulk. I prefer trunks with discreet side or back pockets.
- Lining: A mesh lining provides support and comfort.
- UV Protection: If you spend a lot of time outdoors, trunks with built-in UV protection are a bonus.
- Durability: I look for reinforced stitching and quality fabric that can withstand sun, saltwater, and chlorine.
Trying Them On
If possible, I always try on swim trunks before buying. Sitting, walking, and moving around in them gives a good sense of comfort and fit. If ordering online, I check return policies just in case.
My Final Tips
- Pick trunks that suit your body shape and personal style.
- Prioritize comfort and quality over price.
- Think about how and where you’ll use them most.
By keeping these points in mind, I found square cut swim trunks that look great and feel great, making my time by the water even more enjoyable. I hope my guide helps you do the same!
