    This is an early review. On unpacking this bivy I was really impressed with the quality, accurate sewing and quality materials used. The two zips worked perfectly, quality, and again were very well sewn in. The design, shape and size could not be better, making it super light for ultralighting. Its got a good length for a tall person, even good area for my ultralight pack which fits in the head end so when the pack sits upright, it also acts as a lifter to keep the netting off your face and angles it down to shoot the rain off well which I really liked, also the elasticated turn buckle to keep the rain flap down, yet still let in air. I personally think The North Face has the ultimate design bivy here. I am very well pleased with it and would most certainly recommend it. I truly love this bivy, I have tried others but none have come anywhere near as good. Thanks! by Graham Clarke (Age 70)

  2. Great Product, Cheaper than Other Online Stores

    Posted by Richard and Susan (WA) on 3rd Jan 2019

    This is a great TNF product - especially as we got them at the sale price. We couldn't see it on the TNF Australia website, but we found it right here in WA - go figure. These are very lightweight (much needed for our minimalist hiking) and pretty cosy. I can see where a heavy set individual may struggle getting into one of these, but we found them roomy enough for our needs. I sweat a fair bit, so while I had some condensation inside, the wife didn't - go figure? Great product - Great price!

  3. Great Product & Excellent Customer Service

    Posted by Stacey & Graham (SA) on 18th Aug 2018

    We agree with most of the other feedback points mentioned on other customer reviews here, we purchased two of these as they were on SALE and they are SUPER lightweight. We also liked the Express Post shipping service - it certainly was worth it - they arrived 2 days later. Yes, we also both got some condensation in this bivy, but you get that in almost every Bivy Sack on the market. This model is very cosy and certainly 'added' some extra warmth on those freezing nights. We also just love the colour and the lightweight design of this TNF bivy. Thanks heaps for a great product!

  4. Excellent light weight bivy

    Posted by Dave on 18th Oct 2017

    Took this bivy snow camping as a light weight alternative to a tent and it worked a treat. Slightly tight to get into as per another reviewer's comments below, but very roomy once inside with enough space to store boot liners and bags. Only some minor condensation in the foot area from the boot liners, but sleeping bag was bone dry. Didn't sleep with the hood zip closed, but wasn't too claustrophobic in quick tests.

  5. Super Lightweight, but You will Have some Condensation

    Posted by John & Sarah (Vic) on 14th Oct 2017

    I purchased two of these as they are SUPER lightweight. The Express Post shipping service is worth it - they arrived in 2 days! Sure, you will get some condensation in this Bivy, however you WILL get that in any Bivy Sack, its the same as any single skin tent.
    Pros: 1. Roomy (I am 6'2") and there is plenty of foot, head, and side room. Neither of us felt closed in. 2. Super lightweight and easy to use.
    Cons: 1. If you are a 'chunky-for-punky' it will be difficult to enter. Sure, the one zipper does makes it lighter, but for fat people, it may prove difficult to enter. Especially inside a small tent, not to mention taking a pee in the middle of the night. 2. There is always condensation on my sleeping bag and on the inside of the bivy in the morning. From what I have learned this is pretty much unavoidable with 'all' bivy sacks. With decent weather, and some space to lay your stuff out, it only takes 15-20 minutes to dry out. We both loved this product's simplicity, ease of use and its lightweight design. What's more to like!

  6. Night Night, Warm & Water Tight!

    Posted by Beldon D. on 14th Oct 2017

    Last Winter/Spring I used the Assault Bivy sack on several cold nights varying in temperature from about 0 to -2 degrees, paired with a sub-zero bag, a sleeping pad and a bag liner, the TNF Bivy kept me warm and dry. The first night, I slept in the bivy without a tent or other shelter. On the colder nights I used the sack inside of a snow shelter. With every use, the bivy effectively shed snow and helped to trap more body heat than a sleeping bag alone. Some condensation did develop on the inside of the sack from my breath (as is to be expected with any bivy sack); however, using the mesh opening eliminated this effect entirely. I had plenty of extra room at both the head and foot of the sack for extra gear. Overall, I was very satisfied with this product. With some work, it does fit back into the small carry sack it comes in. The size and weight of the bivy (very lightweight) make it easy to pack and carry and the warmth and water-shedding benefits of the product make it ideal to use in combination with a tent on colder nights or as a minimalist alternative to a tent.

  7. Excellent Customer Service

    Posted by Gordon P. (NSW) on 13th Oct 2017

    Thank you for the excellent customer service I received recently from your OGA staff. I needed this TNF Bivy for this coming weekend's expedition and these guys were able to send it within two days using their Express Post shipping service (costs minimal extra). Arrived on time and it will work a treat. Thanks heaps! We'll be back for more gear soon.
