I’ve always received the spec sheet and “official” ziploc from Haven along with their own branded baggie. But I’ve only bought from them in person at the store, so can’t comment on their mail order system.
Veilance Field Pants, Black, 34. -- $300 (+fees/ship)
Only wore them a couple of times before putting them away for the summer. Just took them back out but think I'd like something different this season.
