Better than my Patagonia R1I've owned a Patagonia R1 for over 10 years and have taken it climbing and traveling with my all over the world. If you own one you already know that it's a phenomenal piece of clothing. So why am I here reviewing the BD Coefficient hoody?
Well unfortunately my r1 got stolen a while back and I was very dismayed to find that the new generation of r1s do not come in a hoody + full zip. Both are essential features for me, so I tried exploring my other options.
Additional things I was looking for were: a large chest pocket (or waist pockets), an athletic fit (I have a classic climber body - wide shoulders + slim torso - so any "boxy" beer-belly cuts were out due to bunching and thermal inefficiency), a wide range of movement (since I'll mostly be climbing in this thing), and a snug hood that moves with your head.
Furthermore, I already own (and love) my Patagonia R2 for any sub-zero expeditions, so I was looking for something that I would want to throw on over a baselayer when say, climbing the Grand Teton in August - just warm enough to keep me going when hiking the approach at 3am, but still breathable and lightweight enough where I can just roll up the sleeves and keep trucking when the sun comes out later in the day.
Here's what I tried:
1) The Arc'teryx Fortrez hoody was incredible, but felt very similar to my Patagonia R2 - too warm/heavy for an active layer in above-freezing temps. Absolutely loved the built-in balaclava though.
2) I ended up buying and then returned a new-gen R1 hoody + 1/2 zip. The fabric and weight are incredible and its cozy as &&, but the boxy fit on a quarter-zip is just doubly-aggravating. The decision to eliminate the waist-pockets was also a bummer, since I previously wore this as a "go-everywhere" piece... not just while out camping and climbing. Torso pockets are nice to have while in the city.
3) Tried on a Patagonia Capilene 4 1/4 ZIp, thinking that maybe I'd just go for a baselayer with a hood and call it a day, but it felt too light and specialized... not something that I'd ever wear around town by itself.
4) There are plenty of other "R1 competitor" fleeces made by REI, etc... that I won't bother listing out here because they are all cheaper imitations. If I'm living in this thing (which I will be), I want to spend the extra $40 and have a total premium feel to the fabric - I want this thing to be so cozy that I can't help but reach for it every morning. None of the cheaper imitations had this appeal (and let's be real, none of this stuff is making you climb harder or hike faster anyways - if it's about comfort, fit, and overall feel anyways, just spend the extra $40 on the jacket that you truly want - otherwise your local Goodwill will have plenty of alternatives that will still get you to the summit).
Finally I tried on the BD Coefficient Hoody (2014 version with the stretchy wrist cuffs) and absolutely loved it. The fabric felt slightly less cozy than the R1 despite being a very similar Polartec fabric (powerdry vs powergrid), the wrist cuffs were too-tight, and the lack of a torso pocket was initially a bit of a bummer (however due to the tighter fit I've gotten over it), but I felt like I had essentially found a more athletic-cut version of my previous R1 full-zip.
However, cue the record squeal: after a week in Squamish, the too-tight wrist cuffs ripped at the seam and so I sent it in to BD warranty. They replaced it (free of charge) with the newer 2015 version, and I am now 100% in love. The new generation of the Coefficient has a much better fabric feel, which is now nearly identical to my old R1. Furthermore, they've eliminated the weird elastic wrist cuffs. The 2015 version of this jacket is now a true R1-killer - literally everything about it is totally on-point. The fit is slightly less athletic, which I'm a little bummed about, but if you don't have a six-pack then that might be a welcome change. The sale price on the older gen is definitely appealing, but personally I would not hesitate to pay retail for the newer version, and this is coming from a former dirtbag who has almost never paid retail for anything.
