Alex K.wrote a review of Arc'teryx Theta SV Bib - Men's on March 24, 2013
These bibs are very low key, but have all the features that are needed for mountaineering, snowboarding, skiing, or hiking in snow or inclement weather. The Gore Pro material is light but also reinforced where it is needed. The cut of the bibs is also excellent allowing for full range of movement whether you are making switchbacks on the skintrack or doing yoga in the snow ( who knows). The biggest plus other than the bomber lightweight waterproof and breathable fabric is that they are bibs. Not only do bibs provide extra protection for wind and a more seamless transition between the top and bottom, but also wears much better with a pack because there is less material and no need for a belt. I would wear these anywhere!
Disclosure: I received these bibs from Gore as part of a project that tests products for Gore.
