If you gonna get 5 mm boots I would just say get 7mm and be done with is. You mentioned you dont want to invest alot of money in multiple items. I am in 7mm boots now and have been for about a month. I will probally start wearing mitts ina week or 2 .
But in all reality it what you can withstand . Some ppl are wimps and in 6/5/4's and gloves and boots and some are 3/2ing it still . Its all preference and what kinda temps you can take
3/2ed it yesterday with a pair of boots. The xcel drylok boots are the best boots I have ever worn.
Maybe try this.
Tomorrows the last time ill be in a 3/2 until next year :(
Hope it'll be good.
Last year i went all year in my 3:2 Quiksilver Syncro with a Nike Dri-Fit underarmour type thing, 7mm Boots, 3mm gloves, and a 5mm hood. This year i got an INSANE deal on last years Quiksilver Cypher Hooded Chest Zip 6:5:4 for 250, and now to buy one new its around 400. I'll be out tomorrow and judging by the chilly air, howling winds, and rain I'll probably be testing out the 6:5:4 for the first time. The only thing i'm worried about is the lack of motion that I am going to have.
