The Ex-Demo wetsuit grading from A to C is based on the aesthetic standard of the wetsuit. It will not affect its actual performance. Ex-Demo products have a 30 day warranty. Grade A1 - Like a new wetsuit. May arrive without original packaging. Grade A - Almost as good as new. Some may have been used for sizing purposes and may or may not still have the labels attached. Grade B- Very good condition. These wetsuits will have been used more frequently for sizing than grade A. Will have some fingernail marks or some fading of printing in certain areas. You may get a used ex-rental or pre-owned wetsuit. Some patch repairs may have been made to these suits, all carried out by our specially selected company based here in the UK.  Grade C- You may get a used ex-rental or pre-owned wetsuit. Some larger patch repairs or panel replacements (these could be in a different colour neoprene to the rest of the suit) may have been made to these suits, all carried out by our specially selected company based here in the UK. There may be some fingernail marks from fitting or the printing may show signs of fading or peeling. None of this affects performance in any way. Please note that discount codes are not valid for purchases of any Ex-Demo products. - The Axiom Thermal came about when HUUB were asked to take one of their best selling suits and add a thermal lining designed to be extra warm and smooth to the skin. Designed with a 2:3 buoyancy combination and glide skin neoprene, the HUUB Axiom wetsuit works to improve your body positioning for maximum drag reduction so you can move quickly in the water. This comes from extensive research in the field, collaborations with the likes of the Brownlee Brothers alongside other triathletes and extensive scientific testing. Specific panel placements and 1.5mm underarm thickness allow you to flex and move with ease so you can perform at your best and make the most of every stroke, while speed cut ankles and smooth skin cuffs ensure a fast transition.
