  • Specially formulated to restore the water-repellent finish found on outdoor clothing.

Grangers Xtreme Repel is a spray-on product designed to restore the water-repellent finish found on all outdoor and technical clothing.

All water-repellent clothing and equipment needs regular maintenance if it’s to continue working at its best. Unfortunately, time, dirt, and even regular wear can all inhibit a garment’s ability to repel water, leaving you wet, cold, and uncomfortable. Washing garments regularly with a specialist detergent – such as Grangers Performance Wash – can help, but even the cleanest fabric will eventually need a fresh water-repellent treatment.

Based on the same technology used by clothing manufacturers to waterproof garments in the factory, Grangers Xtreme Repel restores the water-repellent finish to your garments, leaving you fully protected outdoors. Ideal for treating an entire garment, this product can nonetheless be used to ‘top up’ high wear areas, including collars, cuffs, and sleeves. Heat activation via a tumble dryer, iron, or hairdryer is required.

Grangers Xtreme Repel is suitable for use on all outdoor and technical fabrics, and is perfect for restoring the water-repellent finishes found on all Gore-Tex® and eVent clothing.

"excellent product "

used this spray on my haglofs roc high jacket and it done a fantastic job. I gave the jacket which is a size large a good even covered. I focused on high wear areas where your package or harness sits and had plenty left in the bottle for future re-proofing. this product really dose live up to what grangers say. original performance restored!


"Jacket feels like 'New'"

Sprayed on soft shell coat and tumbled dried as per instructions, it feels like a brand new jacket again. Only down side is the volume it's just on the small side 275 ml/9.3 fl oz and just about got jacket done, would of liked to be able to repeat certain spots. Any chance of just buying a refill bottle (without sprayer) hopefully at at cheaper price.
