Genuine USGI waterproof bivy cover for the Improved Modular Sleep System (IMSS/MSS).

This authentic U.S. Military Issue Modular Sleep System Bivy Cover is designed to provide a waterproof, windproof outer shell around your military sleeping bag while allowing moisture vapor to escape. Made with Gore-Tex waterproof/breathable fabric, the bivy protects your sleep system from rain, snow, wind, ground moisture, and changing field conditions without requiring a traditional tent.

Featuring the UCP/ACU camouflage pattern, these bivy covers were issued as part of the improved U.S. military sleep system and are built for serious field use.

The roomy military design fits over the USGI patrol and intermediate sleeping bags and can also be used with many commercial sleeping bags. A covered zipper provides easy entry and exit, while snap closures allow the upper portion to be secured around the sleeper for additional protection from the elements.

For camping, hunting, bushcraft, preparedness, military collections, or a genuine USGI sleep system, the MSS bivy is an extremely versatile piece of field gear.

Condition

Grade 1 – Very Good Condition: Genuine military surplus in very good, fully serviceable condition. May show minor signs of previous use or storage including light dirt, cosmetic marks, writing, slight fading, or other normal handling wear. No major holes, tears, or damage affecting normal use. Exact appearance will vary.

Because these are genuine military-surplus bivy covers rather than commercial reproductions, minor cosmetic differences between individual covers should be expected.

A Proven Military Sleep-System Component

The bivy cover is what makes the USGI Modular Sleep System substantially more versatile. Rather than carrying a tent solely to keep your sleeping bag out of the weather, the Gore-Tex bivy creates a protective outer layer around the sleep system itself.

Use it with the appropriate USGI sleeping bags for the traditional military configuration, pair it with your existing sleeping bag, or carry it as a compact weather-protection option when minimizing shelter weight and bulk.

This is genuine U.S. Military Issue equipment—not an aftermarket or imported reproduction.

CONDITION:

Grade 1: Very Good Condition to Like New

Grade 2: Good condition, No holes, fully serviceable. May show signs of use to include dirt and discoloration. 

Grade 3: Small pin holes or may need seams re-heated/taped.

Great!

Mone was supposed to be grade 2, but I can't find any evidence that it was ever used. Cheaper than the woodland version because of the horrible ACU but built just as bulletproof.

Grade 3 bivy

I bought the grade 3 bivy expecting to find some damage to it, but there nothing wrong with it that I could find! Absolutely the best price for a ucp bivy anywhere.

Simple & Affordable

**A steal of a deal at OTS, regardless of condition.** I purchased a grade 1 bivy. Basically brand new, the bivy i received was in excellent condition no holes, abrasions, or cuts, it only lacked the original plastic packaging.
** A tarp or poncho, bivy, and a insulated mat is a go to budget shelter system. Easy on the wallet and light on the back! **

New in Bag!

Received new UCP pattern Bivy Cover in NIB condition. First - if you don't have one of these - get one especially at this price! It's a vital part of the modern 'Ranger Roll'. I've bought other bivy covers (woodland) from OTS previously. I haven't done a side by side comparison of the two but it seems this newer UCP bivy cover is 'thinner' in material than the woodland bivy. Could just be mil-spec 'generation' changes by the military or it could just be me. There doesn't seem to be a 'standard' NSN tag in this bivy cover but the NSN number is listed on the tag (doesn't say 'NSN') and is stamped on the material. Again it is likely just a 'newer' gen issue thing. Bivy is well made by 'Tennier Industries' a good quality outdoor products company I'm familiar with. If it's a 'copy' - it's a good one. I did just notice the elastic draw string around the hood to enclose around user's head is only exposed on one side with a plastic 'keeper' while the other side is 'sewn into the stitching' and does not protrude through the 'tunnel' as you'd expect. Could be a minor defect (easily fixed) but doesn't affect the bivy's overall function.

Grade 2
Good condition

I ordered one grade 2 and one grade 3. The grade 2 appears to be in basically new condition. Flawless as far as I can tell. The grade 3 has one small tear on the top panel that will be easily repairable with a cheap gore tex patch and a stain on the bottom. It is otherwise clean and in very good condition. Cheap way to get two people outfitted for winter camping

Great buy

Great deal, great price. Brand new still in the plastic. Never been touched. I liked the first one so much I bought a second before they sell out. Not gonna find these new for long. Soon they'll be nothing but used. I don't care about the pattern. I can put a poncho over it if I want to change the UCP. Besides, it may not work for summer and fall, but, it does well in winter and spring. Can't beat the sale price from One Thief. Great deal guys!!!!

Great customer service

Love the military ECWSS, this is the second set I'm purchasing so that my partner will (perhaps) be persuaded to come winter camping with me! Came in great condition as expected.
Have slept in a car and in a tent in -33°C weather with this system. It's great! Also best emergency sleeping bag for the car in Canadian winter. Loved the hand written note with my purchase <3 Thanks OT!
