“Sleeping Pants” Alpha Direct Pants Experience. Other options for UL?

I have a Senchi in 60gsm. It tears pretty easily and has a few tears that I’ve sewn back together. It doesn’t stretch much and it is somewhat difficult to put on, but I really like it anyway. The fabric is a perfect balance of warm and cool, perfect for a woman my age, if you understand what I’m saying. I’ve thought about making alpha leggings for myself and if I did, to prevent tearing and make them easier to put on I would make them more like pants than tights. With my windpants over them I think I could withstand some really cold nights sitting around without a campfire.

I just got the Alpha Direct 60 g/sm pants.

they weight 83 grams

my 3/4 Capilene Thermal tights weigh 143 g

my 3/4 HH lightweight wool zoned tights weigh 172 g

MB down pants 205 g

The down and Alpha pants are about 10cm/4” longer than the other two.

I would estimate the relative warmth (underneath a shell pant or inside a sleeping quilt/bag):

Down pants : 5
alpha 60 and Cap thermal: 2
HH: 1

I have not used the alpha pants yet, but based on my experience with the shirt, it think it will be the perfect sleep layer: soft, cozy and very light.

For true winter camping I would bring down or synthetic high loft pants.

Just used the Alpha Direct pants for a 3 night backpacking trip with my family.

Worked great, as expected. Lows were around 40 F and very humid. Used a 40 F EE quilt with zippered foot box, and an Uberlite pad.

First night I slept in just those, and was a bit chilly, so the following nights I layered them under my (very thin and lightly stretchy) hiking pants. That added a touch of warmth, making me more comfortable.

In camp I layered them under my hiking and rain pants.

One morning before getting up I swapped layers inside my quilt, so the alpha pants were outside my hiking pants, covered by the rain paints. Just to make  removing layers for hiking easier after breakfast.

Ryan also used them here:

Tjaard – I’m trying to decide between Alpha 60 or 90 weight for a use fairly similar to yours. I want them to be sleep pants in a Feathered Friends Vireo bag (25f lower half, 45f upper) as well as a warm layer I can wear under a shell around camp or while hiking on a cool, wet day. I’m in the Pacific Northwest, so typical 3-season temps go down to mid 30s/low 40s.

Now that you’ve tried out your 60-weight pants, do you think they are the right choice? Or do you wish you had the 90s? Any recommendation for my scenario? I generally run a bit warm. Thanks.
