Lightweight insulated piece
This jacket is a good balance between lightweight and warmth. I use it on hikes especially during the day. Unlike some mid layers, it does offer some wind shield protection, which is a plus. Having said that, wind protection is better left to a shell that is designed for that purpose. A good buy and as usual, great service from altrec.com.
I purchased the OR Radiant Hybrid Jacket for cool/cold weather hiking. Size Large fits my 135#, 5'4" frame well with room to under-layer a polyester hoodie. With "brushed", "brushed grid", and "radiant" fleece, this zippered, 95% polyester/5% spandex highly technical jacket delivers much warmth, breathability, wicking, and insulation in a rugged, comfy yet stylish jacket. There is an upper-right side front zip pocket for a phone and handy thumb holes. After several wearings and washings, my green OR Radiant Hybrid looks good. The only wear is some snagging in the smooth outer fabric but this jacket was intended for rough outdoor wear.
5'4", size medium: Sits nice and low on hips, sleeves are perfect (fine with or without thumb loops), shape is very feminine and flattering, zipper pull is tiny (but maybe that was on purpose), chest pocket is high on chest/shoulder (so us girls can still put our phone in there), no hand pockets makes it feel very sleek and adds to flattering profile, layers nicely. Seems like the smooth face may pick and pill over time, but don't know yet. Berry is deep rich color, in the grape juice and raspberry family. I like it.
