Sea to Summit Venture II Women's Sleeping Bag Long
The unique WaveLoft construction uses thick layers of THERMOLITE insulation looped together to gain extra loft and trap pockets of warm air, providing increased warmth in colder conditions. The baffle construction also eliminates the frustration of getting tangled in loose lining as all lining fabrics are attached to the shell fabric. The Venture also features thicker insulation in the footbox, reducing the chance of cold feet interrupting your night’s sleep and a women’s specific tapered rectangular shape that is wider at the hip and narrower at the shoulder. The Free-Flow triple-zip design ensures your sleeping bag retains maximum warmth and efficiency when needed and multiple ventilation options when it’s not. The half zip on the left side of the bag provides freedom of movement for both arms, additional ventilation and means the top third of the bag can be folded down as a mini quilt. The full length, two-way right side zip and separate foot zip transforms the bag into a full quilt for when the mercury climbs higher than expected. ThermoliteThermolite insulation provides lightweight warmth for all activites. Sea to Summit uses Thermolite insulation in many of the sleep system products in different forms. Sleeping bag liners use Thermolite fibre knitted to create the Reactor Thermolite fabric. Sleeping bags use Thermolite insulation that is designed for superior warmth and exceptional softness.

This bag is lightweight and comfy for a synthetic bag. I had lots of room with the long size, which is nice when you're camping and want to be comfy. The zipper looks sturdy as does the rest of the bag's construction. It's definitely worth the price point.

I took this on a trip where the nighttime low was 32F. Unfortunately the bag wasn't warm enough fully zipped up with hood cinched down. Also, it doesn't pack down as small as other sleeping bags -- it takes up a LOT of space in my 65L pack. I'm really disappointed because the bag is great in many other ways: comfy material, excellent zipper placement options, cinch-down hood. It's fine for warmer weather, but sadly it didn't live up to its temperature rating or packability. I'll be returning it for a warmer bag.

I returned this and opted for a down alternative to save on weight and space. Hoping I don’t regret that for rainy west coast weather! I do like that this unzips fully to turn into a duvet.

I was cold on 35 to 45 degree nights. This is despite a Therm-a-Rest NeoAir XLite Sleeping Pad - Women's (r value 5.4). I was fully clothed and wore gloves, hat and a nano puff jacket. I think part of the problem was it was too tight and also drafty along the zipper. If I slept flat on my back all night it may have been better. I toss a bit and am a side sleeper. I am tend to get warm easily when sleeping. I am from Florida so I am not used to the cold. A hot flash would have been nice on this trip.The fabric was soft and comfy and the zipperswere great.
I love this sleeping bag, particularly the foot-end zippers, that allow me to put on my shoes and penguin-walk out to start my stove in the morning, without having to get out of my cozy bag until my hot coffee is ready and I am warmed up. Or at night when I realize at 3 AM I need to close the vent on the top of my tent, which has only outside access. I can slip on my shoes and step outside without having to get out of my bag.
Look, I love Sea to Summit but this is not suitable for -5°C, let alone -12°C. Tried it on a frosty night and had to give up. Used it on a cool, 7°C spring evening and it was fine. Please be realistic about labelling your products, guys. Seriously. Don't waste our time and money.
This bag has a great feel to it, soft on the inside and the outer material feels quite durable. The zipper(s) have a good design that allows for multi vent options, or open it right up for a quilt. There's also an anti-snag runner behind the zipper. The colour, though not important, is very nice. Surprisingly light weight for a synthetic sleeping bag and also packs quite small, though not as compact as down. I purchased the large as I do not like to be restricted and there's plenty of wiggle room for anyone under 5'10".
Really nice bag and love the features. The fact that it zips on both sides and has a zipper at the bottom to cool my feet is amazing. Nice and comfortable and warm bag.
This is so comfortable. It is light and fluffy and like sleeping in a cloud. I like all the zippers, especially the one opposite the main zipper so I can fold over like a blanket.the one at the feet is a nice feature as well. I didn't give it a 5 star because I noticed rather soon after using it a few times, the outer fabric tends to get caught and snag easily. I am not using anything sharp around it's just my hands and the natural way you pull up a sleeping bag. There are a few pulls along the main body of it as well. I'm not being rough with it so the is disappointing. I took a great deal of time to figure out which bag to buy. It's an investment and ultimately worth it.
I actually have the 32f bag, but I thought to pop in here and let people know this series of sleeping bag from sea to summit is top notch!6 zippers give you the ultimate control over the bags temperature, making it comfortable in hot and cold weather. They are a bit finicky though.The 32f feels pretty dang warm, will test it out in a couple of weeks.The compression sack is good quality, and semi-waterproof.This bag on sale is a steal! A bit heavy, but still a great bag. The 32f is light enough for backpacking-for me at least.
