The timbers are joining the MLS in 2011, and have to give up their nike sponsor, its going to be strange seeing them in an adidas kit, as Portland is the HQ of Nike and the current sponsor of the ULS team.
Here is my take on the home and the away Timbers kits.
For the home Ive used the green and yellow from the kit on the shirt, with the yellow pinstripes, and the motif is on the socks, with white sock turnovers, shorts, shirt bottom, collars and cuffs for contrast with the green.
The change is in white, with a green and yellow chest band, and a green V neck and matching cuffs. The socks and shorts are interchangeable with the home kit.
The flag on the back is that of Portland. The Alaska Airlines logo is left of as its a Seattle based company, and the timbers logotype is on front, taken off the new crest. The new crest is used on the shirt, without the lettering, and on the sock overturn is the axe motif.
