Review: Brief! - My fella wanted brief trunks - he got his wish. I just liked the colour 😍
Review: Small and less coverage on rear - I prefer the powerflex eco brief over the this solar version, which has smaller hip width. Also the back has less fabric, so your cheeks stick out. Not so comfortable for me. The nylon fabric is super nice, but again, the poweflex eco with the wider hip is the same fabric. As far as I know, these are the only 2 speedo models currently that use nylon instead of cheap polyester. Nylon is so much softer and feels great on the skin.

## Features

- LONG-LASTING: Lycra Xtra Life fabric lasts 5-10x longer than ordinary spandex by retaining original shape and resisting color fade
- QUICK-DRYING: Low-moisture absorption for fast comfort right out of the water
- NO PINCHING: A front gusset creates comfortable, breathable room around the crotch area. Center back seam streamlines fit
- A BETTER FIT: Specialty 9 Thread Flatlock Technology molds to your body's natural shape and keeps everything in place through vigorous exercises

## Questions & Answers

**Q: Are these really stretchy?**
A: Probably somewhere between stretchy and really stretchy.  I could be several inches bigger in the waist and still wear the suit I own but it would be tight.  So yes, the materiel is stretchy.  I rinse it after each dip and it seems to fit the same each day.  A well constructed suit.

**Q: Size M in brief underwear. 30-31 in jeans. Muscular legs and butt. 5'5". What size do you recommend?**
A: I am 5’7” with muscular legs and normal butt. I bought 3 Speedo Powerflex Eco Solar swimsuit briefs or bikinis with 1” wide sides and I bought and wear size 34 because I am big-boned and a bit muscular. I bought two red and one white swim briefs and their material seems to be more resistant to chlorine and a bit thicker. This might cause some drag. Before purchasing these swim briefs, I would go through swimsuits like water. They would wear out because I have been swimming 6 days a week since August 2020. I consider myself a swimmer wannabe. I usually swim daily between 1k to 1 mile if I have time enough.  with these swimsuits I cannot be any happier.
I hope this helps.

**Q: My husband is a 33 in pant size what size shoulf I order him for best fit?**
A: my order was for a 36 and the person it was was ordered for wears a 36 waist and it fits fine.

**Q: What did I buy in swimming briefs ?**
A: I purchased Speedo Solar 1 swim briefs, size 32 in red color.
