Jammer advice

No buoyancy with jammers, just reduced drag in the water.

I use Speedo brand, and have only had the one pair.  For me, the sizing chart was accurate; bear in mind that they are a snug fit, like tri shorts.

I like TYR polyester jammers.  They hold up well to chlorine and I've gotten at least two seasons out of them.  The lycra ones I wore previous only lasted about a year.

If you want something with a bit of bouyancy let me pass along a suggestion I got from someone here on BT months ago that has worked well for me.  Try Gold's Gym Compression Shorts.  They are made of neoprene (wetsuit material) and I picked them up at Walmart for $10.

Inexpensive and comfortable.  Just remember to rinse them off well after a pool swim.

x2.  Not real expensive and hold up to chlorine well.  I gained about 10% in speed when I went from trunks to jammers.

TYR jammers have been good to me for over a year with a ton of pool workouts.  I rinse them off every single time they are used.

X3.  I did have to size up from my normal 36 to 38 as the 36 were just way too tight.  They are still in good shape after almost a year of 2x a week swimming, but they have faded along the seams.  Must be the actual threads that are now a lighter color.  I just think of that as a badge of honor for my dedication.  There is no structual damage.

I had a similar question.

Here is the thread. Hope it helps.

I don't understand this.  Why would you want to go faster in training?  I always swim in my trunks and have time targets that I am trying achieve.  When I wear tri-shorts for races, then I'm pleasantly surprised at how easy it is.
