Good fit, very comfortable.
Bought 3 pairs to try and have ended up buying another 6.... So comfortable
Interested to see how long they last but so far seem very good value and lovely and soft. Quick delivery after ordering and no plastic packaging.
Great quality, great price and great service. Quality is much better than I thought it would be for the price! Quick delivery too and fitting through postbox is ideal 👍 would definitely recommend.
Great product and quality .
Great value and comfortable to wear.
Too loose for medium
Bought these bamboo pants for my husband. He tells me they are very comfortable and sizing was spot on. Been washed quite a few times and seem to be good quality as holding the shape and colour well. Would buy again.
First impressions are good, much more comfortable than cotton pants I am used to wearing.
