2015 Model. 2 Year Guarantee. The Dearg II Hi-Vis BackPack cover from CÀRN has been designed with one purpose in mind - SAFETY! For walkers, runners, cyclists and motor-cyclists. Made from a Lightweight Water-Resistant 210T Nylon material. Taped sealed seams and waterproof threads used throughout the cover. Fits a range of packs from approximately 10 to 25 litres in capacity. The pack used in the images is our 25L BackPack (dimensions = h48 x w30 x d17 approx). 2015 Update: Based on the Dearg 1 feedback we have revised down the cover size range from the original 10 to 30 litre. Unique top cross velcro fastener for easy adjustment/fitting/removal. 2015 Update: The new model now comes with stronger Velcro and increases to the contact areas. The cross strap is now also constructed of a firm polyester material which aids handling/fitting. Day visibility comes from the Hi-Vis Fluro Green material. Night visibility comes from the reflective print and vertical reflective bands. 2015 Update: The new model has been designed with additional reflective print details for improved visibility. 2 horizontal webbing bands for clip-on rear facing lights. Webbing Opening = 40mm. Webbing Height = 25mm. 2015 Update: We have now changed the band material to a 2mm Rubber which helps to support the weight of the rear facing lights and keep them at the correct angle(s). Elasticated edging with bottom pull toggle system to ensure that the cover fits snugly to a range of pack sizes. Weight - 100 grams. Rear light(not included) attachment. Hand Wash/Wipe Clean only and reproof outer material. When fitting firmly press the hook & loop(Velcro) together and tighten the pull toggle.
