Waterproof jacket breathability dramatically improves the less impediments you put in the way of the moisture escaping. That means less pockets, seams and unnecessary zips where possible. Pace have taken a great, breathable fabric in eVent and adopted those principles admirably, keeping the 3x3 super clean and slick but for a single back pocket.
The result is a jacket that is not only light and packable but very breathable and comfortable for extended use. There is no hood, but not everyone feels the need to have one - you make your own call on that - and it only keeps to the 3x3's founding principles: small, light and slick.
On chilly rides we have appreciated the large zip and velcro cuff tags, easily pulled even with thick gloves, and the low cut back gives excellent coverage when in the riding position. One handed adjustment, easily snugging up the high collar, completes it's bad weather protection - this is clearly a jacket that has been designed by riders who know their stuff and aren't afraid of going out in the rain themselves.
We would prefer to have an adjustable hem to seal out drafts, rather than the half-elasticated one on the Pace but that really is nit-picking, and it pretty much did the job every time.
The best bit is the price - at under £100 this truly is a classy, top performing jacket for a steal. It cuts an excellent compromise between functionality and light weight, keeping the weather at bay without including any features that don't further that goal. An excellent bit of clothing for all types of cycling.
