Nice, real nice

These are very nice shorts. I actually won the world surfing championships whilst wearing them and I feel they really contributed to my winning performance. Only gripe is that they €15 in France and £26 in the uk…

Surfing/Beach sports short

Value for money. Neither extra ordinary nor complaining quality

Thermo bonded seams a bit dodgy

Got one earlier last year, the seams fell apart, which left a huge gaping hole in not so flattering spot after about 10 wears. Worn this one twice so far and the thermo-bond seams look OK, however, still a bit wary and always checking if it's gonna unravel again. Otherwise, the material is quick drying, lightweight and the fit is brilliant.

Sitzt super und macht was es soll

Ich habe mir die Boardshoards fürs Wakeboarden geholt. Sie sitzt super und man ist extrem beweglich im Vergleich zu einer Badehose. Meiner Meinung nach sollte man sich auf jeden Fall noch eine Unterhose für drunter holen.
