No. Just...no.  These things are skimpy as heck and made out of material that doesn't seem like it would last one wash cycle.  The legs are super short and rode up my thighs almost immediately.  Fabric is extremely thin, virtually see-through, which I suppose makes for good ventilation but I can't imagine these being durable in any way.  Immediate return.

I have some undershirts from Lapasa that I wear under my ice hockey equipment and to work out, they're fantastic.  This material does not lend itself to underwear though! Would not recommend.  Have been searching for an affordable alternative to Saxx which are great but very expensive.  Please see my next review for a product that has promise...
