User Review: Sierra Designs Wicked Fast
Fill: Heavenly 800 Down
Temperature Rating: 30
Weight: 1 lb 8 oz
Price Paid: $199
This is a great sleeping bag, and I am surprised there aren't more reviews on the internet about it. Here are the positives: It is incredibly light. SD makes the claim that other manufacturers have used less durable fabrics to create light sleeping bags, and having shopped around this seems to be the case. The fabric used by SD is light, but feels plenty durable. It does not stick to my skin, and warms up real quick. The down is heavenly, and seems to be warmer than the rating would suggest.
The hood is a nice feature and does decrease the volume of space that needs to be heated...so it does seem more efficient. It is very compact and comes with a nice stuff bag, though I think it could be compressed much smaller with a compression bag. The foot vent is a nice feature as it does create enough of a draft to slightly cool down if needed. And personally I like the half zip... it doesn't continue to zip down till I finally role out. It is roomier than I expected, and rolling around in the night is done with ease. Finally, the weight is fantastic. There are slightly lighter bags, but I feel like this bag will meet my needs and last a long time.
As for the negatives: The foot vent is both a positive and a negative. The only negativity is that it could have zipped open even more and it seems too delicate to have both feet stick out. So I just stick one out and pull the other leg up...which works quite nicely. SD also claims there is a draft tube, and I don't know what their definition of draft tube is, but there isn't one in the classical sense. That being said, I haven't had a problem with that one bit...especially since I typically use a tent (so no wind) and I am a warm sleeper (I think I could take it down to 20).
Hope this helps someone looking at this bag. I really like it and couldn't find much info when I was researching it. Also, some have stated that it doesn't have insulation on the bottom...this isn't true. I think that was an old model and they have since insulated the bottom of the bag. It is a great ultralight bag!
