It depends how much you can fit in the sled without making it top heavy.  Typical winter camping gear can be bulky.  The pulk systems can handle 100s of pounds of weight but you’ll want to pack your gear efficiently and keep your heavier items towards the bottom of the sled and lighter, bulkier items on top. Also, note which harness you are using. For heavier loads (80lbs+) you’ll want to use our heavy duty Expedition harness.
