Not used it yet, but looks good quality, I like the one way drink valve. Would of been nice to of had a frothy head on top of the bottle😊 Also brought a pair of your grundies, very comfortable,good seams and shape hold. If you took the ventilation holes off the legs perhaps they could make a nice pair of budget cycling shorts? Just a thought, on a pension don’t you know. One last thing, would be good to see some branded frame chain stay guards, motivational stickers maybe with the odd fat lad in the broom wagon. ‘Rite good ‘ol company Ma! All the best Perry Isle of Wight (no it’s not flat ‘ere!).
