REVIEWS


Just thought I’d drop a note saying what an incredible product you’ve made. I bought a Fatboy 400 for a winter camp with my Scout troop. Got to camp and realized I’d forgotten my sleeping mat. So all I had was my old wool army blanket to put between me and the snow. I’ll admit it took about an hour, but it slept the night almost too warm for the -20C night. The ground was hard, no mistake, but I was warmer than I can remember being sleeping on what was basically a wool-covered sheet of ice.
As a fan of winter camping, I look forward to many warm and comfortable nights in the bush. Thank you for making such a great product.

Travel size products, best sunscreen out there.

Great as always but picture is misleading a bit, this is the small travel size bottle not the full size. I should have read better, still like the set nonetheless of course. Heres a picture for comparison.

Sun Bum kit a saver!!

Great little bag full of sunscreen for my grandson. Glad we had it to take it everywhere with us. A little pricey but he needs it so instead of taking bunches of bottles we had this.
