These are a great product at a great price. This is my second purchase and I expect to purchase more in the future.
Great fit and so comfortable. Delivered as promised and at such a great price. I am replacing bamboo trunks from a major manufacturer which cost so much more than the Spairs which I can 100% recommend. Indeed I am just about to order some more as I am so delighted with them.
Great price, great service, great product
Excellent quality do not ride up really soft Really good service only draw back they do not fit through letterbox as stated box needs to be slightly smaller but apart from that they are great will definitely be ordering again
Very good and comfortable
Great price and first rate product, fitting very comfortably.
Excellent value
Very comfy, great price and free delivery 👍 I have purchased 6 pairs already and no doubt will purchase more in future.
Very Comfortable and unbelievable for the price - very pleased with my purchase and also good sizing - I’m a XXL
Lovely and comfortable with plenty of ballroom.
Would have preferred longer leg, that said these are comfortable and soft, nice colours, good value for the money.
Good product, rapid delivery
Good fit, but material feels quite thin
Boxer legs don’t stay in place, crease up to the groin. Very uncomfortable. Sent compliant but no response. Terrible customer service.
Not large enough not even close
