hillclimber wrote a review of Patagonia Lightweight R4 Jacket - Men's on August 31, 2005
Originally I had misgivings as this jacket did not seem warm enough. After 4 months on, I have come to appreciate it when climbing in cold gusty conditions. With underarm stretch panels this jacket breathes under exertion, something that you could never accuse the original R4 of. Even with an additional layer it's less bulky than the R4 and it's more fashionable for round town use. However as soon as the temperature drops, it's back to my trusty R4.
