I really dont notice im even wearing my pack. And i would venture to say it is heavier than most with all the stuff i carry in it. Some sleds dont have room for storage unless you add racks and frames to add the bags too. Like my polaris pro-ride chassis. I may go back to a traditional tunnel sled simply for on sled storage options. I carry a tool kit, shovel, spare gloves, spare goggles, spare socks, spare balaclava, water, food, and other emergency items. Sometimes theow a sno bunje in there also. Its heavy but as long as a pack is designed for riders, with waist and sternum straps, is adjusted and worn properly then its usually
Not noticeable. Atleast not to me.
