I have the MEC T2 L/S Zip Hoody and Cap 4 – I thought I might sell one or the other but find myself using both a lot. The T2 is a lighter piece, less warm with shorter raised ridges and air spaces on the interior of the fabric, but that means you can use it in warmer temperatures or as a thin baselayer under other layers. The Cap 4 is much warmer with taller ridges and deeper air spaces on the inside of the fabric and doubled-up fabric on the hood.
Also picked up a good lightweight rain glove called the Cloudraker (they probably renamed it by now – just look for their lighest-weight gaunlet waterproof glove). It was cut a full size oversize so had to order down a full size.
I paid the same for membership and delivery. Customer service was excellent – received a wrong-sized item and MEC told me not to bother going through the trouble of shipping it back and sent the correct size. Very impressed with them.
