Son very happy with his birthday pants!! Nice soft fabric. Obviously I didn’t get to see them on!
I suffer from chaffing on legs so went for these pants that are a lot less expensive than equivalents . So far so good
Absolutely great comfortable washes great turn out the ten
Great fit, super soft and really comfortable to wear all day. Will be buying more!
Great fit, well made, soft, comfortable and airy. Excellent price too.
Thought I would give Spairs a try when I came across their trunks on the internet and pleased I did. For the money they are decent underwear, in fact the cost is very good considering they are Bamboo trunks. Would definitely buy again.
