Several years ago my wife and I replaced our two-zippered-together-mummy-bags sleeping bag setup with a Feathered Friends Spoonbill double bag. This was a game changer for our frequent backpacking trips, reducing our sleeping bag weight from over 4 pounds down to an incredible 2.5 lbs with the same or even better warmth. How was this possible? The secret is the false bottom. Since down insulation is mostly compressed (and thus useless) when you’re laying on top of it, you might as well just get rid of it altogether on the bottom! This is what Feathered Friends did with the Spoonbill – the top and sides are full of high loft 950-fill down, while the bottom is simply a thin fabric sheet. The result is a massive weight savings without hardly any warmth penalty (assuming you have a decently warm mattress).
Recently while rethinking my solo backpacking setup, I wondered if I could cut some significant weight with a similar false bottom solo bag, instead of the normal standard mummy bag design I’ve been using for years. After extensive research I stumbled upon the Timmermade Wren false bottom sleeping bag. The specs boasted a 19oz weight for a 20º rated bag – impressive considering my 15º bag weighs 33oz! Plus the pricing was competitive with comparable high end sleeping bag brands – also impressive considering that the Timmermades are custom tailored bags. After discussing some questions and options with the owner/maker Dan Timmerman we got the order rolling. What you see here are the results: the Timmermade Wren False Bottom sleeping bag, 20º rated, 950 fill down, 19oz (1lb 3oz), $420, with custom printed fabric.
