Tried using a sleeping bag liner instead of a heavy bag last week in the Smokies
Got tired of lugging my 4 pound winter bag on summer trips so I grabbed a $30 silk liner and my old 50 degree bag instead. Picked a night that dropped to 45 and honestly I slept fine, no shivering at all. The pack weight difference was huge, like 2 pounds lighter easy. Has anyone else found a good combo for trimming down summer gear without freezing?

Wait was this a fluke for you or have you done it a few times now? I did almost the exact same thing on the Ozark Trail last June, swapped my 20 degree bag for a 40 degree quilt with a silk liner and came out fine even when it hit 48. That extra 2 pounds off my back made the whole hike feel like a totally different experience.

Yeah I actually saw a post on r/ultralight talking about how layering a silk liner under a bag can push the rating down like 10-15 degrees, which makes sense with what you did on the Ozark Trail. @the_evan your swap sounds solid, I'm def gonna try that next trip.

Man that weight difference is no joke. I did something similar on the Long Trail a few years back, swapped my old 0 degree bag (which was way overkill) for a 30 degree quilt with a thin fleece liner and it worked great down to about 38 degrees. The kicker was I ended up sleeping way better because I wasn't sweating in that heavy bag anymore, plus I could actually move around inside the quilt without getting tangled up. Silk liners are legit though, they trap heat way better than people give them credit for (especially if you tuck the ends in right).
