I recently got to test out a sample of the new Dare2Tri Mach V.5 wetsuit. I followed the following test protocol:

Warm-up: 500 Steady, 8×50 strong w/ 0:20 rest

Test: 100 easy, 2×100 on 3:00

Repeat test with swimskin, Challenge 4Speed wetsuit, and MachV.5 wetsuit.

I would compare the suits based on my best 100.

My fastest 100s:

Speedo – 1:19.1

Swimskin – 1:18.6

Challenge 4 Speed – 1:14.5

MachV.5 – 1:11.6


The MachV.5 was 2.9 seconds faster!!! I’m really excited to race in this wetsuit this year.
