Disappointing

Returned as huge chunky waistband so can’t wear under a skirt or trousers. No gusset so not very comfortable and no ankle off so ride up under trousers so very disappointing

Perfect base layer

I ordered these pants as the closest product to Wintersilks, which I wore every winter when Iived on the East Coast. They have an oddly long rise, and being 5’, I am folding the waistband over until I decide whether it’s worth paying for alteration. Otherwise, they’re an ideal thickness for an underlayer, and I appreciate their availability in petite.

Light layer works perfectly!

I have bought three or four pairs of these over the year as I wear them constantly throughout the winter and into spring. They are comfortable, true to size and fit nicely under tight jeans or dress pants. It is important to follow the care instructions.

The leggings are great - thank you! They fit well everywhere, but I had to take the waist in a little, but that's not a problem.

Overall decent

The fabric quality is pretty good. The M runs large on me, but it is so difficult to fit women as we come in such size mixes. The legs should be a little longer. The sewing seems to be good. I have not used yet so cannot comment. I did hand wash and hang dry and they did well .

Do not like new style.

I do not like the thick elastic waistband. This is a new, these pants never had that thick of a band.

Thin, so works under tighter clothing

Fit is fine, but the material is very thin compared to years ago. But apparently no one makes mid-weight or heavy weight silk underwear anymore. If you need more warmth, options are wool or synthetic. Would ONLY buy this on sale. Not worth the regular price. Also, oddly full of static cling, no matter what you do...

The waist band is too wide

There is one big flaw in the design of these silk pants and that is the waistband. It is very wide and rolls up. It just doesn't sit right. I have other silk pants with a normal elastic waist and it is a much better fit and feel. I would not recommend these pants.

Wonderful Silk Interlock Pants

I have worn Land's End Silk Interlock long johns for years. This pair was purchased to replace a pair that finally wore out. The fit is as good as ever. I expect this pair will last for many years as the old ones did! I highly recommend them to anyone dealing with cold weather.

Real silk is hard to find these days

I wanted to give 3.5 starts but don't know how. I agree with those who say these need a re-design, as the very thick waistband comes up way too high (can be folded down). I miss Winter Silks, where multiple waist styles were available, and all styles had cuffs.That said, these fit true to size and they're silk, which is exactly what I need and it's gotten hard to find! I don't find they ride up, as some suggest. I where mine over my liner socks and under my wool socks, and they keep my legs warm w/out adding bulk. Does the job.
