I've had this for four months. Now that summer is here, I don't expect to wear it again until winter (we generally don't get rain here between May and October), but it was excellent in cooler weather.
This is a jacket for keeping you warm while being active. It keeps the wind and rain out while keeping your body warmth in. It's a windbreaker, not an insulated jacket, so if you're standing still or sitting, it won't keep you warm. When I'm active, however, it keeps me warm even on very cool, damp days. When I'm not active, I wear warmer clothes underneath or an insulated jacket.
The oversized flaps that can be unzipped under both arms will be much appreciated when riding my mountain bike up a mountain during cool weather by allowing air to circulate to keep me cool, but before I begin a long downhill I can zip it up and stay warm.
If you ride a bike in wet conditions, you'll appreciate the extra long tail that keeps you dry in the rear.
I only have two complaints:
1) It doesn't have pockets. However, it was my fault for not checking this before buying. I might have bought it anyway. I can always use a small fanny pack for things I would have carried in a jacket pocket, such as a cell phone and portable GPS.
2) I hate the reflective markings on the sleeves and back. However that's because I ride mainly offroad and don't need anything reflective. I think that most people who ride on the road in dark or wet conditions will appreciate this feature.
This is only the second time I've bought a Sugoi product. The first, a pair of running shorts I bought last year, are holding up fine, so I see no reason why this windbreaker won't hold up also. The construction quality looks excellent.
